ABSTRACT
We have documented a boat-building procedure that is unique in Bengal (India). The typological name of the
boat is chhot. A smooth-skinned, rabbeted, and stapled boat of Bengal with a 'v'-shaped cross section and
prominent keel. The project took place in Dihimondalghat of Haora district on the bank of river Rupnarayan.
Digitization of the entire process of boat building was undertaken on this EMKP, UK project. Panchanan
Mandal and his four sons created a full-scale boat measuring 35 feet in length and 9.5 feet in the cross beam.
Documentation of chhot is important as the boat type is no longer used on the river. The crafting skill of chhot
boat building will disappear shortly. It is the first project on the digitization of a boat in India. The presentation
is through still photography and videography along with narratives.
Keywords: stapled, chhot, Namasudra, jolui, shell built

UNDERWATER CULTURAL HERITAGE AND MARITIME MUSEUMS
This part of the world (Bengal, India) is not landlocked but rather riverine. Though we have a rich
maritime culture, underwater cultural heritage was not documented. Riverine culture has been
documented through various ethnographic studies but maritime and riverine culture has not been
studied in depth. Maritime ethnography has been a key tool to document Underwater Cultural
Heritage through the study of present boats. Hence this study is an exemplary study on the
documentation of Underwater Cultural Heritage.
Documentation of a boat and the way of making that boat is the prime focus of the present study. The
technology, which it follows, is meticulously documented. A boat has been commissioned for the
entire research work. Traditional boat builders built that boat using their traditional tools.
Minute-to-minute documentation through photography, videography, and interview of the entire
process of boat building has been recorded for posterity.
It was felt that immediate documentation of the watercraft is highly important because all traditional
boats as well as skills of boat building are in grave danger. The reasons of course are simple. It is one
of the many cumulative effects of the development of the world we live in. Heavy siltation on the
riverbed is caused by many anthropogenic as well as geographical conditions, of which obstacle in the
natural flow of water is the most important. It is high time to document the watercraft and the process
of the building because already some are lost and some are at stake and thus one of the oldest
technologies is going to be lost altogether, shortly.
The most important source of information other than major finds of the ancient boat is that provided
by the boats of the ancient building traditions, which still exist today. In this context, an important
aspect put forward by McKim Marriott (1955) in the form of the concept of 'Over Developed
Technology' is highly acceptable. According to him, a particular technology forms a cobweb with the
various aspects of the social-cultural domain like belief, ritual, custom, etc., of that particular society
both in time and space. This integral interactional pattern of society carries in it, the traditional
concept of civilization. Therefore, following McKim Marriott's arguments, it can be stated that the
1

�study of a particular traditional technology enfolds the historical background of the community that
practises it and also the ecological conditions and economic requirements of that area at a particular
time. It will, thus, enable the researcher to understand the complex interactional pattern of traditional
material culture and social customs as well as the patterns of belief in a single study.

CASE STUDY
The chhot-builders of West Bengal Project: Documenting the vanishing craft knowledge of a unique
boat-building tradition' is the title of the initiative of a team, in a collaborative project between the
University of Exeter, UK, and Central University of Haryana, India.
Material knowledge— understanding of the resources, skills, technologies, and social values
necessary to create and maintain the material world around us- is endangered. In this precarious
world, the diversity of material knowledge is being lost at an unprecedented rate as mass-produced
goods and industrial technologies subsume or replace local practices. Changes to the environment and
habitat loss—through industrialisation, deforestation, green grabbing, and other factors—jeopardize
local ecologies and raw material sustainability. Meanwhile, shifting socio-political dynamics, such as
large-scale urbanisation and rural depopulation, imperil long-practiced forms of learning,
apprenticeship, and knowledge transfer.
The Endangered Material Knowledge Programme (EMKP) supports knowledge holders, practitioners,
and scholars to conduct new research on critically threatened material knowledge globally, especially
in understudied areas and where local funding opportunities are limited.
About the boat
The chhot, a typological variety of lower Bengal boats, is unique as it can venture into the open sea.
Probably this is the only boat of Bengal (presently State of West Bengal in India) which was used for
maritime activity in the Bay of Bengal. The chhot is a rarity in that its planking is joined using metal
staples, a technique unknown elsewhere in India that echoes sewn-boat construction, while its
keel-less construction echoes traditional watercraft in southeast Asia.
About the boat builders
Panchanan Mondal, a 70 years old boat maker who was a master boat builder at his young age is the
resource person and advisor to his team. The guild of boatmakers comprises his four sons Amol
Mondal, Monimohan Mondal, Dilip Mondal, and Deepak Mondal. Except for Mohimohan all other
sons reside in the same hamlet but they all maintain separate kilns for food. Panchanan Mondal
received his knowledge of boat building from his father at the early age of 14. All four sons of
Panchanan also received training in boat building from their father Panchanan. It has been noticed that
the last five generations are with boat building activity. And they are experts on chhot boats.
Panchanan belongs to the Namasudra community, a caste under the Hindu caste system. As per
Risley, Nama Sudra, a non-Aryan caste of Eastern Bengal termed as Chandal, “engaged for the most
part in boating and cultivation… They are the only Hindus employed in the boats (bajra) hired by
Europeans; they form a large portion of the peasantry." In lower Bengal Namasudra is a predominant
caste group engaged with cultivation as well as fishing.
Area of the project
Dihimondalghat is a village situated on the left bank of River Rupnarayan in the district of Haora,
West Bengal, India. Rupnarayan is the name of a river that confluence with river Ganga a few

2

�kilometres downstream of Dihimondalghat. The origin of the river is in the Chhotonagpur plateau.
Damodar, Silabati, Dwarakeswar, and Mundeswari are the sources of river Rupnarayan.
Boat building technology
Chhot boat, a shell-built boat with a keel, followed a tradition of Bengal to fasten two planks with a
kind of metal pin (staple-like) called jolui. This process of fastening is termed as stapled technique
here which is unique and perhaps only visible in some parts of Odisha, some parts of Bihar and Uttar
Pradesh, and the entire West Bengal, Assam, and Bangladesh.
The process of boatbuilding is described herewith in sequence:
1. Shaping of wood: Selected timbers are sawed under the supervision of the chief boat builder.
The quality of wood and its length is one of the important criteria for this selection procedure.
Planks of different dimensions are sawed in sawmills but hand saws are also occasionally
used. The wood used in the boat construction are Krirish (Samanea saman), Sai Bilati
(Pithecellobium dulce), Arjun (Terminalia arjuna), Babla (Vachellia nilotica). In earlier days
boats were used to build with Sal (Shorea robusta) and Segun (Tectona grandis) timbers.
2. Firing and Bending: A trench of requisite length is used to heat specific planks. Saw dust is
used as fuel. After requisite heat treatment planks are placed on a raised device to bend planks
as per requirement. For twisting certain planks generally, planks are placed on the ground and
paved with pegs.
3. Erection of keel (Figure 1): With the help of support structures keel is laid on the ground with
a proper contour. A string is tied in between two terminal ends of the keel. The string is used
to test the perfection of the alignment of the keel in the same plane.

Figure 1. Entire keel after erection. Various support systems are used to hold the keel in its position.

4. The support structure: A series of coconut logs two feet in length is placed on the ground at
regular intervals and fixed with wooden pegs to act as the support structure of the bottom of
the hull and specially the keel plank. Curved keel planks are joined with the central keel plank
with a complex scarf and wooden pieces are used to support the structure. At the two terminal
ends of the keel plank tripod or diagonal supports are used. Galvanized wires are used to hold
the central plank with the ground.

�5. Planking (Figure 2): Planking starts from the mid-ship portion of the boat on either side.
Planks if needed to be bent are heated first and bent accordingly and then placed on the
position and temporarily clamped. Finer adjustments are marked with a traditional device
called karan (fixed divider) and boa karan (expandable divider). Clamps are removed and
marked portions are chiseled out. Again planks are placed in their actual position and with the
help of karan a scratch line was marked along the seam line on the central keel plank and also
on the outer surface of the garboard plank that will be fitted later. Now the garboard plank is
removed again. A medial line is marked with kursud, a marking device, along the thickness of
the garboard plank as well as on the keel. Based on the marked scratch on the central keel
plank half lap portion of both connecting surfaces is removed. That is termed as ban kata the
rabbet. After doing rabbet on both connecting surfaces planks are now ready to fit in the
marked portion. Various types of clamps are used to keep the plank in position. Then a slot is
made at regular intervals with the help of a chisel. This slot is generally done at a distance of
char angul (four-finger width) (roughly 3 inches).

Figure 2. Hull planking. Planks used in the hull planking are run parallel to the keel.
Smaller planks are used in the stem and stern region.

6. Rabbeting: Rabbet is the half lap. On the thickness of the plank, half of each side is removed
to fit it with the other side. All planks of the hull are attached to this type of joint.
7. Stapling (Figure 3): When the planks are aligned, shallow slots, about one-eighth of an inch
in width, are cut across the seams on the inner side of the boat at intervals of 4 inches. These
intervals depend upon specific positioning in different sections of the boat as also on the
expense to be incurred on the boat. The length of these slots on either side of the seam is of
varying ratios. The jolui are never equally positioned across two planks. Three-quarters of the
length of the slot lies in the plank that has the tongue of the rabbet on the inside. This is
usually the newly added upper plank. The remaining quarter length of the slot lies in the plank
that is already fitted. Jolui, a flat double-pointed staple of galvanized iron, is first driven at an
acute angle into the plank, which is already in position. The pointed end of the jolui is then
driven into the newly added plank in an angular fashion.

�Figure 3. Entire hull structure. Hull planks are run parallel to the keel but the
sheer strake connects stem head to stern head.

8. Clamping: Various types of clamps are used to hold planks in a fixed place. The use of ropes
and bamboo poles is the most important device for clamping called jat bari.
9. Joining: Garboard strake at the mid-ship portion is fitted first then to lengthen the garboard
strake vertical scarf joints are used. All hull planks use scarf joints whereas the topmost
planks and next to sheer strake use a complex scarf like that of the central keel plank.
10. Framing: Before putting sheer strake cross beams are added. The number of crossbeams
depends on the length of the boat. Generally, the distance between two cross beams is three
feet. For fishing boats, cross beams are aligned with the outer surface of the boat but for
cargo, those are protruded out. Cross Beams are joined with the strake with a kind of groove
that is complex. After putting crossbeams, futtocks are added at a regular interval. These
futtocks are curved pieces of logs holding each side planks with the help of specially made
iron nails. After placing all futtocks (baras), floor timbers are also added corresponding to
each pair of futtocks.
11. Hull planking and accessories: After completion of framing now boat builders used to put
some additional support structure like outer stringer, temporary deck, steering oar and paddle.
After doing all those activities the outer surface of the boat needs to be made smooth on all
joints of the plank.
12. Caulking: After completion of all carpentry work caulking takes place on every horizontal as
well as vertical joint of planks. A type of cotton is used to plug on the entire outer surface of
the boat. After that, extract sap from the Gaub fruit (Diospyros malabarica) is painted on the
outer hull as well as on the plugged cotton.
13. Sail: Rectangular sail made of cotton cloth is used on a single mast placed centrally. Sail is
hung on the yard not medially rather than in a 60:40 ratio.
14. Trial run (Figure 4): After completion of the entire boat chhot boat was launched on the river
Rupnarayan after a brief ritual performance and then sailed.

                <text>Ceramics are one of the major artefact types that are found in maritime archaeological excavations. Some of these ceramics have letters written in ink on them. Tthese letters are categorized as “Gang (綱)”. “Gang” is an important historical material to "Gangshou (綱首)", which is the name of a group of leading trade merchants operating during the Song dynasty in the literature records. Gang written on ceramics have several types, such as “gang”, “family name + gang”, “gangsi (綱司)”, and “family name + gangsi”. These “Gang” ceramics have been found in ruins on Hakata (博多)  and in northern Kyushu in Japan, Mado (馬島) underwater ruins in Korea, and Penghu Island (澎湖島) ruins in Taiwan. It was also collected from under the sea near Hong Kong. In mainland China, these are also excavated from the Nanhai I Shipwreck (南海), Shipwreck of Quanzhou(泉州) Bay, Strata of Song Dynasty in the Nanyue (南越) Palace ruin, and in Guangzhou(広州). This study examines merchant excavation locations of "Gang" identified ceramics within the maritime archeological context.</text>

                    <text>“Winged” stem and stern in Southeast Asian lashed-lug vessels: from ethnography to archaeology

Pierre-Yves Manguin (EFEO/French School of Asian Studies, Emeritus Professor)
ABSTRACT

So-called “winged” bows were among the first boat characteristics that were used to identify the expansion of
shipping technologies of the Austronesian speaking people across both the Pacific and the Indian Ocean. Pioneers
Haddon and Hornell were the first to recognize that small outrigger dugouts observed in East Africa shared a
“winged” stem (and stern) construction with comparable boats from Insular Southeast Asia. Starting with the
Butuan archaeological excavations in the 1980s, a number of much larger plank-built vessels of the first and second
millennia CE have been brought to light in Southeast Asian waters that clearly belong to this “winged” technical
tradition. They all belong to the lashed-lug shipbuilding tradition which is specific to Southeast Asia. This
presentation will bring together the presently available evidence on such matters, with detailed observations, and a
first attempt at building up a typology of such vessels.
Keywords: lashed-lug, Southeast Asian archaeology, Southeast Asian ethnography, winged stem

INTRODUCTION
Pioneers Alfred C. Haddon and James Hornell were the first to recognize that small outrigger dugouts
observed in East Africa and Madagascar shared structural characteristics with comparable boats from
Insular Southeast Asia. They thus brought material evidence of early maritime contacts between the two
shores of the Indian Ocean (linguistic and anthropological affinities with Madagascar had by then be
recognised). They first examined the design of outriggers (Haddon 1918; 1920; Hornell 1919). Hornell,
however, soon shifted his attention to what he termed the “winged” stem and stern pieces of these small
boats, a possibly more stable common characteristic of crafts, built thousands of miles apart (Hornell
1920; 1928; 1934; 1944). On such small dugouts with only one or two raised side-planks, both dugout
extremities are raised by attaching to them one or more blocks of wood carved out in the shape of a
“winged“ stem or stern pieces. In such boats, there is no need for a stem post, the extremities of the
planks being fastened to these “winged” blocks of wood —at some distance from the acute-angled ends

�of the hull, and therefore without the need to impose a strong curvature, difficult to achieve, on the
planks.
We know by now that such a design is not limited to small dugout craft but may also be found in larger
plank-built boats in which the dugout has evolved into a true keel piece. Solid ethnographic work by
Nick Burningham (1990) recognised and discussed such features in what he calls the “stemless craft” of
Ende or the “seven- part craft” of the Bajau of Tawi-Tawi (Burningham 1990; 1992; on the Bajau lepa,
see also Nimmo 1990). A close observation of the boats built by the Moken sea nomads living along the
upper northwest coast of the Thai-Malay Peninsula, on the other side of Southeast Asia, show distinct
similarities with those of the Sama Bajau of the Philippines (Ivanoff 1999). It is clear from these
superficial remarks that, on ethnographic evidence alone, a considerable amount of comparative work
remains to be done on such matters.

WINGED STEMS IN SOUTHEAST ASIA
Starting with the Butuan archaeological excavations in the 1980s, several large plank-built vessels of the
first and second millennia CE were brought to light in Southeast Asian waters, which also clearly belong
to this “winged stem and stern” technical tradition. This point was raised in one of the first systematic
descriptions of one of the Butuan boats (Clark, Green, Santiago et al. 1993; see Figure 1), and discussed
in much detail, after additional data was brought to light during further excavations of the Butuan boats
by Ligaya Lacsina (2016).
This raises the possibility of connecting this particular boatbuilding technology with one other design
that has now been firmly associated by nautical archaeologists to Southeast Asian shipbuilding, i.e. the
“lashed-lug” technology. One essential task that nautical archaeologists working in Southeast Asia had
assigned themselves was to identify technical characteristics that defined a local shipbuilding tradition
different from those of neighbouring areas. In the early phases of nautical archaeology in the region, this
was essential as most recoveries of ship timbers were brought to light as broken and dissociated
fragments, after looting or during rescue operations of damaged sites (and this still happens too often).
The “lashed-lug” technique is not exclusive to Southeast Asia, as already noted by Hornell (1935), but it
is unique within Asia, and it has been one key identifier of the Southeast Asian origin of archaeological
finds. If it is proved to be usually associated with winged stem and stern pieces, such identifications of
archaeological finds (or of ambiguous textual sources) of Southeast Asian craft will be more secure, and
a more reliable typology will be built up.
This brief presentation only purports to bring together new evidence presently available on such matters,
mostly from Indonesia, as one assembled and many fragmented ship remains have been found in the past
years, many of which could be studied at leisure. They all clearly belong to the lashed-lug tradition, and
all can be associated with winged designs for stem and/or stern.
One major discovery by Indonesian archaeologists was that in Rembang (north coast of Central Java), on
the beach ridge site of Punjulharjo, of a 16 m long, remarkably well preserved lashed-lug and stitchedplank boat dated to the 7th to 8th century CE (Abbas 2010; Mochtar 2018; Manguin 2019) (Figure 2). The
fastenings with ijok ropes of the planks together and that of lugs to frames, stringers and vertical
stanchions are particularly well preserved, as are the stem and the stern pieces, up to the third strake, as
depicted in the following drawings. The stern and the less well- preserved stem are not symmetrical, but
are clearly built following the same design. The “winged” blocks of wood are fastened not only by
treenails inserted into theirs seams, but also by two kinds of ijok lashings: one passes outside of the hull,
and fastens the extremity of the keel piece and the first block; the other is inside the hull, and must have
been made taught by hammering in a rounded, bevelled wedge.

�Figure 2. The Punjulharjo ship: 3D image (by Ipso Facto and P.-Y. Manguin) Stern (left) and stem of the
Punjulharjo ship (drawing by P.-Y. Manguin).

Such rope fastenings of stemless stem and stern pieces have survived to this day under different guises in
a few small boats (in Lamalera, Lembata, or in Jambi, Sumatra (Figure 3) (Barnes 1985; Dwyer and
Ackerman 1998). Daniel G. Dwyer recently remarked that some boat depictions of Dong Son drums and
of archaeological remains in Vietnam may have also used a comparable fastening (Dwyer 2015a, 2015b).
Such lashings are no longer used in the Butuan boats, in line with the fact that, being younger by a few
centuries, their planks are no longer stitched together with ijok as are those of Punjulharjo. Only treenails
and tenons and mortises have by then remained in use to assemble the hull (Manguin 2022).
One rescue operation carried out in 1989-1990 by Indonesian archaeologists and the present author at
Paya Pasir, which turned up to be the heavily disturbed harbour site of the 11th to 14th century CE
neighbouring site of Kota Cina (North Sumatra). Only broken timbers belonging to a variety of small to
large boats and ships were recovered, all of them of the lashed-lug tradition, and all dated to the period of
activity of the Kota Cina site (Manguin 1989; in press).
One major find belonging to a middle-sized vessel (some 15 to 25 m) was that of a well-preserved
stepped stem or stern (Figure 4, left). Contrary to what we have seen so far, it was elaborately carved out
from one single block of wood that was fastened, as usual, to the extremity of a keel (now broken off).
The end parts of the planks would have been fastened to the stepped wing sides by way of dowels (one or
two dowel holes are still preserved on each step).
Other damaged pieces from different craft may be identified as the tapering extremities of now broken
off keels, to which separate “winged” stem or stern pieces would have been attached. The twin bevelled
surfaces starting after the stem or stern end are bored with dowel holes that would have maintained the
garboard strakes in place (Figure 4, right). It appears that, as in the Butuan boats, no rope lashings were
used to fasten the stem/stern piece to the keel (here again, in line with the late dating of these boats, none
of which were of the earlier “stitched-plank” type).

Burningham) / (bottom): a biduk of the Upper Batang Hari, Jambi (as drawn by van Hasselt 1882, pl. XCIV).

Other sites of Sumatra have in the past years delivered comparable remains of broken off keel pieces, all
unfortunately from disturbed sites, along the shore of the Kota Kapur site (Bangka-Belitung), or at
Margomulyo (Air Sugihan site complex, South Sumatra). All appear to have been fastened to similar
stem/stern pieces. They have not been dated by C14, but both sites were in activity during the 1st
millenium CE.

DISCUSSION
Scholars of the early 20th century, with the limited evidence they had at hand regarding the ancient
shipbuilding traditions of Southeast Asian people, only considered the small boats they could then
observe (dugouts with only a few raised planks). We know by now that large ocean sailing ships were
built by Southeast Asians as early as the first few centuries CE, and that the boat builders of the Maldives
—roughly half way on one possible route between Indonesia and Madagascar— kept building their midsized plank-built fishing craft in ways that clearly derive from former Southeast Asian lashed-lug
technologies (Manguin 2011). It is therefore logical to conclude that those Austronesian speaking people
who settled in Madagascar during the 1st millennium CE has sailed there in large plank- built vessels
(Manguin 2012; 2016). This will have to remain in the realm of informed speculation, pending a
systematic study of textual sources that would tell us if some of the Malagasy larger ships would show

�traces of Southeast Asian shipbuilding traditions, or the discovery of a relevant shipwreck in the Indian
Ocean.
On more secure, if limited grounds, it now appears that the shape and the mode of assemblage stem and
stern pieces following the ubiquitous “winged” design can vary considerably from craft to craft, and in
different periods. It may well also have differed from region to region within Southeast Asian waters, but
boats and ships being essentially mobile, it is rarely possible to ascertain from archaeological finds if the
craft are locally produced of came from overseas).

                <text>So-called “winged” bows were among the first boat characteristics that were used to identify the expansion of&#13;

Haddon and Hornell were the first to recognize that small outrigger dugouts observed in East Africa shared a&#13;

                    <text>15th century carnelian bead cargo of the Indian Ocean World: a conversation starter on
collections-based research in the Asia-Pacific
Jennifer Craig (APConf5 Committee Member, Publication Lead Coordinator)

ABSTRACT
The topic of this abstract fits best within the Collections-based Research Session because existing museum
collections of carnelian beads from two archaeological shipwreck sites were analyzed. The sites include different
ship constructions located at the far ends, to the north and south, of the Philippines; and they carried comparable
artefacts. Both the Pandanan (1460-1487 CE) and Santa Cruz (1488-1505 CE) shipwrecks carried cargoes of
similar ceramics (i.e. Chinese Jingdezhen and Thai Maenam Noi) and black glass beads (i.e. west India soda
alumina); yet these sites also carried dissimilar cargo in both the ceramics and glass beads. Both sites also carried
disproportionate carnelian beads. The resources to conduct the work to study carnelian are the morphological
analysis of measurement and descriptors, technological analysis of SEM and compositional analysis of LA-ICPMS. My research questions ask what geographic patterns these analyses indicate of the carnelian beads: What is
the source of the carnelian? Where were the bead workshops? What sailing routes did the carnelian move over to
ultimately shipwreck off the Philippines? The expected results are that riverine systems that connected interior
Indian carnelian were used to move raw material to west India bead workshops, via the Indian Ocean, Bay of
Bengal into the Straits of Malacca to Southeast Asian entrepôt.

INTRODUCTION
In January 2023 I attended the Society for Historical Archaeology conference. This North American
focused conference included a luncheon on Collections and Curation that invited practitioners of
Collections-based Research. Wondering if I might be an oblivious participant, as someone who had
recently completed a PhD dissertation on shipwreck beads collections stored in the National Museum
of the Philippines, in the luncheon I found that there was a very clear definition of what collection-based
research entailed for the North American Archaeologist/Curator, “using existing collections to pose and
answer scholarly questions/it is a form of archaeological excavation in its own right. Searching through
the contents of boxes and old catalogs found deep in repositories is a process full of
discoveries/collections that can be generated over a period of decades by academic institutions,
museums, volunteer organizations, and cultural resource management firms” (King 2014). This led me
to think that if I was unaware of this definition then perhaps it is because it is not a concept in the Asia
Pacific Region. I was curious to discuss with colleagues in the APConf 2023 of our ideas of collectionsbased research, including how might we like to define our own regional version, and I also wanted to

1

�share what remained to published of my work on the NMPL collection of carnelian beads from two
shipwrecks.
The topic of this paper fits best within this Session 23 on Collections-based Research because my case
studies are museum collections of carnelian beads from two archaeological shipwreck sites in the
Philippines. My research questions and methodologies are grounded in maritime archaeology,
linguistics and museology. I wanted a space to explore what epistemologies I bring to collections-based
research within a session of peers doing work on “collections''. My archaeology epistemology intersects
with maritime-historical –indigenous-material science archaeology. Maritime archaeology in that my
theoretical framework is the maritime cultural landscape, connecting artefacts and places across land
and water. Historical archaeology in that I mostly work with objects made within the second millennia,
with a slant of Art History in that I work across decades. Finally, built out of my exploration of linguistic
methodologies to study cultural concepts and a human worldview, I am guided professionally by
Indigenous-feminist archaeology. I use heart-centered practices: (1) show care for the living and the
dead; (2) recognize we are all emotional and social as well as intellectual beings; (3) act upon our needs
for responsible relationships with each other, with a range of communities, and with archaeological
records, and; (4) emphasize rigor (Supernant, Baxter, Lyons, &amp; Atalay 2020). Archaeometry contributes
to the rigor of my answers to research questions on connectivities across large areas in short periods of
time.

CASE STUDIES
The case studies under consideration are the shipwrecks Pandanan (1460-1487 CE) and Santa Cruz
(1488-1505 CE). The first was a Vietnamese-Chinese barge located in south-west Philippines and the
second a South China Sea Tradition open-ocean vessel located in north-west Philippines. Aside from
the hull design and location, several differences exist between the cargoes. The Pandanan cargo included
Chinese Longquan celadon, Jingdezhen and Guangdong with Burmese Twante, Vietnamese Chu Dau
and Thai Si Satchanalai; High magnesium black glass beads morphologically identical to black west
India soda alumina (in similarities); Small and long red west India soda alumina glass beads; three agates
(one pendant, two rough cornerless cube/pentagon). The Santa Cruz cargo included Minyao Chinese,
blue and white Cham and Go Sanh Cham wares, Sukhothai fish plates; Waxy yellow east India glass
beads; Potash high potassium blue wound glass beads; 54-106 hexagonal prism carnelians/agates; 2684 small lozenge carnelian/agates; one cornerless hexagon quartzite. Despite these differences the
shipwrecks also carried three similar types of cargo: Chinese Jingdezhen and Thai Maenam Noi
ceramics; black glass beads (i.e. west India soda alumina) (Craig 2021; Craig &amp; Dussubieux 2022). I
return to these details later as I consider context and connectivities across vast water bodies of the Indian
Ocean and the seas in the Southeast Asia Region. This paper narrows into the discussion on the carnelian
beads.
Carnelian beads
The range of carnelian/agate quantity comes from the inventory notes at the time of excavation and my
morphology analysis results. The Pandanan excavation report included three agates. My morphological
analysis recorded one pendant, and two rough cornerless cube/pentagon. The Santa Cruz inventory
included 190 carnelians/agates beads. My morphological analysis recorded 54 hexagonal prisms and 26
small lozenge carnelian/agates.

�RESOURCES
The resources available to conduct the work include the National Museum of the Philippines directors
Jeremy Barns and Angel Baptiste, staff in the Archaeology Division Mary Jane Bolunia and Eusebio
Dizon, staff in the Underwater Archaeology Division Clyde Jago-on and Bobby Orillaneda, and staff
from the Records Section Nida Curvas. During fieldwork I appreciated the research assistance by Emil
Bersamira and Bobby Orillaneda. The fieldwork was supported by the Social Science and Research
Council of Canada MCRI, Society for Nautical Research, Brasenose College and Oxford University
Meyerstein. The stone beads were exported for compositional analysis with Laser ablation inductively
coupled plasma mass spectrometry (LA-ICP-MS), this details the elemental “recipe” (periodic table) of
the stone to compare with known geological sources, by Laure Dussubieux (Chicago Field Museum,
Elementary Analysis Laboratory) with funds from the National Science Foundation (BCS 1321731) and
the Bruce and Barbara Trigger Award of the Anthropology Department McGill University; and
statistical analysis and training supported by MITACS Research Training Award (2020). En route a
fortuitous encounter with Dennys Frenez (Università di Bologna, Department of History and Cultures,
Prehistory and Protohistory of Asia), Mark Kenoyer and Randall Law (University of Wisconsin–
Madison, Department of Anthropology) with permission from NMPL colleagues, led to technical
analysis of the bead bore putty impression samples at different magnifications (300X, 100X, 50X, 20X)
with SEM- Hitachi 570 (University of Wisconsin–Madison, Laboratory of Experimental Archaeology).
The technological analysis unanimously pointed to Indian craftsmanship where long faceted hexagonal
beads are generally drilled with larger diameter diamond drills, and the smaller tabular lozenge shaped
faceted beads are generally drilled with thinner diamond drills (Kenoyer pers. comm. 25 April 2017).
Randall used statistical analysis with program SPSS [Table 1] using canonical discriminant analysis
(CDA) to compare the Pandanan and Santa Cruz carnelian compositions to known agate sources (Carter
&amp; Dussubieux, 2016; Law et al., 2013).
Table 1 lists the Santa Cruz and Pandanan carnelian cargo average concentrations and standard deviations for the
elements used in the statistical analysis with samples in parts per million (PPM) converted to log10 values. These are
compared to the four geologic sources Ratanpur, Mardak, Shahr-i-Sokhta and Ban Khao Mogul (reproduced/adapted
from Carter and Dussubieux 2016:327, Table 3). When comparing these tables it is possible to see the difference between
the elements and their ranges to notice how some line up but most are out of range. This indicates possible shared
geography of source material but currently outside these locations. For example, with select elements the bead 1170E
fits within the PPM range for Scandium (Sc) and Uranium (U) but not otherwise.

�FRAMEWORK
My research questions ask what geographic patterns these compositional, morphological, technological
analyses indicate of the carnelian beads: What is the source of the carnelian? Where were the bead
workshops? What sailing routes did the carnelian move over to ultimately shipwreck off the Philippines?
The results indicate the first two questions are well researched and relatively clear routes can be drawn,
while the third question points to gaps in the literature.

RESULTS
The expected results are that riverine systems that connected interior Indian carnelian were used to move
raw material to west India bead workshops, via the Indian Ocean, Bay of Bengal into the Straits of
Malacca to Southeast Asian entrepôt.
My compositional results are that the Santa Cruz carnelian was sourced from an unknown location
(Figure 1/TABLE 2), likely along the Deccan Traps of India (Carter &amp; Dussubieux 2016). Perhaps there
was some overlap with Ratanpur and Shahr-i-Sokhra but that's largely speculative (Figure 2).
Technological analysis results of Indian craftsmanship adds details on the workshop location likelihood.
The bead workshops near Ratanpur were in Limodara during the sixteenth century. The initial process
of drying the stone and changing its colour by heating continued in Limodara (Dames 1918, 143; Lunde
&amp; Craig 2015, 22). Kenoyer, Vidale &amp; Bhanet (1991, 45) show the location of agate bead production
exclusively in Gujarat with raw materials from Ratanpur and Limodra, both situated along the Narmada
River, flowing into the sea downstream of Broach (Lunde &amp; Craig 2015, 27).

�Figure 2 A biplot of the agate/carnelian geologic sources with the agate/carnelian artifacts plotted by their first two
discriminant functions. The four labeled artifacts are outliers from those that have either a primary or secondary PGM
assignment. All four were predicted to belong to one Indian source. Of those four, one had a PGM in the Thai source
and three had PGMs in the Iran source.

The importance of ports in the transport system is significant because the Gujarat area was strategically
placed along the main shipping route. Early 16th century records by Ludovico di Varthema (travelled
from 1503 to 1508), mentions the agate/carnelian trade of Cambay and the wide web of foreign markets,
reached by ‘Mohammedan sea-faring traders’ along the Red Sea, East Coast of Africa, the
Mediterranean and the Far East (Arkell 1936, 299). For the carnelian/agate source Shahr-i-Sokhra the
port of Hormuz was likely. During the years 1325-1622 CE, the bulk of the India trade passed through
Hormuz, and continued to do so even after the Portuguese took the city in 1514 CE (Lunde &amp; Craig
2015, 26). Hormuz had a significant advantage over Aden, its main rival. “Ships out of Hormuz could
sail to Gujarat almost all the year round, hugging the coasts of Makran and Sind, while Yemeni and Red
Sea ships were completely dependent on the monsoon system, with narrow windows of opportunity for
safely crossing the Indian Ocean.” (Lunde &amp; Craig 2015, 26).
Contemporary to the dates of the shipwrecks Pandanan and Santa Cruz, the port Rander (destroyed by
Portuguese in 1530 CE) was described by Duarte Barbosa in 1514 CE as trading with Malacca, Bengal,
Tenasserim, and Pegu. Prior to the silting of the estuary to Rander in the 16th century, stone beads were
shipped out of Cambay by Portuguese and Gujarati merchants along with glass beads from Broach. The
importance of Bharuch from the turn of the millennium through the 18th century, located 25 nautical
miles from the sea on the north bank of the Narmada River (Maqbul Ahmad 1960, 58; Lunde &amp; Craig
2015, 24), indicates the heavy riverine traffic of the Narmada River. Narmada River to Limodara and
6

�on to Bharuch/ Broach on southeast of Cambay’s estuary and Tapi River to Rander share a baseflow
source in the Deccan Plateau grabens (Vanderkluysen et al. 2011). This is to say the mineral content of
the geology is similar (Das, Krishnaswami &amp; Kumar 2006).

CONCLUSION
In conclusion, presumably stone beads exported via Broach were along the river systems or in the
saltwater on shallow lightering-craft. The archaeological and historical text evidence together indicates
that bead production and port location were inextricably linked in Gujarat (Lunde &amp; Craig 2015, 27).
However, large gaps in the literature still remain for the story on how carnelian beads may have moved
through the Bay of Bengal into the Straits of Malacca to Southeast Asian entrepôt.
Returning to my raison d’etre of creating this session for discussion in our APConf 2023, on ideas of
collections-based research, including how we might like to define a version in the Asia Pacific region. I
consider the beads and Rey Santiago as I go into this question. Rey was my bead mentor. He curated the
records and objects of bead collections in the NMPL, cultivated methodology of their study, (and the
part that hooked me onto these small finds) extrapolated the stories of each bead from water and land.
With these intangible and tangible inputs to my collections-based research, I propose that we, “pose and
answer scholarly questions/it is a form of archaeological excavation in its own right. Searching [with
mentors/ghosts/spirits/colleagues] through the contents of boxes and old catalogs found deep in
repositories is a process full of discoveries[/magic/kinship-making/affirming that include] collections
that can be generated over a period of decades by academic institutions, museums, volunteer
organizations, and cultural resource management firms [so as to gather stories and storytell]” (King
2014; Supernant 2020; Supernant, Beisaw, Garrison, &amp; Surface-Evans 2020).

                <text>The topic of this abstract fits best within the Collections-based Research Session because existing museum&#13;
collections of carnelian beads from two archaeological shipwreck sites were analyzed. The sites include different&#13;
ship constructions located at the far ends, to the north and south, of the Philippines; and they carried comparable&#13;
artefacts. Both the Pandanan (1460-1487 CE) and Santa Cruz (1488-1505 CE) shipwrecks carried cargoes of&#13;
similar ceramics (i.e. Chinese Jingdezhen and Thai Maenam Noi) and black glass beads (i.e. west India soda&#13;
alumina); yet these sites also carried dissimilar cargo in both the ceramics and glass beads. Both sites also carried&#13;
disproportionate carnelian beads. The resources to conduct the work to study carnelian are the morphological&#13;
analysis of measurement and descriptors, technological analysis of SEM and compositional analysis of LA-ICPMS. My research questions ask what geographic patterns these analyses indicate of the carnelian beads: What is&#13;
the source of the carnelian? Where were the bead workshops? What sailing routes did the carnelian move over to&#13;
ultimately shipwreck off the Philippines? The expected results are that riverine systems that connected interior&#13;
Indian carnelian were used to move raw material to west India bead workshops, via the Indian Ocean, Bay of&#13;
Bengal into the Straits of Malacca to Southeast Asian entrepôt. </text>

                    <text>2001 Convention and UNESCO’s Capacity Building in Asia-Pacific
Chihiro NISHIKAWA

ABSTRACT
The topic of this paper fits best within this Session 18: Revisiting the UNESCO Foundation and Advanced
Courses for Asia-Pacific: Status, Development, and Challenges because it reviews UNESCO’s capacity
building efforts and activities with an aim to identify challenges and propose future course of action relating to
underwater cultural heritage in the region.

2001 CONVENTION
The Convention on the Protection of the Underwater Cultural Heritage (the 2001 Convention) was
adopted in 2001 by the General Conference of the United Nations Educational, Scientific and
Cultural Organization (UNESCO) to fight against commercial exploitation of underwater cultural
heritage (UCH). According to the Convention, UCH is “an integral part of the cultural heritage of
humanity and a particularly important element in the history of peoples, nations and their relations
with each other concerning their common heritage” (UNESCO 2001: Preamble), and provides vital
evidence and information about human history and the interaction of civilizations with all kinds of
waters, e.g. oceans, lakes, rivers, flooded caves and swamps.
The 2001 Convention aims to assure UCH protection and sustainability at the same level as those
provided to land-based heritage. To this end, the 2001 Convention regulates site protection measures
and obliges its States Parties to impose sanctions in cases of violations of the measures. It also
provides ethical principles such as in situ preservation and the respect of all human remains located
in maritime waters. The 2001 Convention moreover underlines the importance of research,
information and education to the protection and preservation of underwater cultural heritage and
contains, in its Annex, 36 rules for activities directed at UCH, providing practical guidelines for
underwater scientific and archaeological interventions. Today the rules have become internationally
recognized scientific standards for underwater archaeology and research, applied by many
specialized institutions and universities.
UNESCO regional meetings and training workshops
The 2001 Convention entered into force with 20 ratifications in 2009. To promote the principles of
the 2001 Convention and help countries develop capacity in the protection and management of
underwater cultural heritage in line with the objectives of the Convention, UNESCO organized a
series of regional meetings and technical workshops. For Southeast Asia, UNESCO organized,
between 2009 and 2011, extensive training workshops in underwater archaeology to build regional
capacity in identification, research and protection of underwater cultural heritage, owing to the
generous financial contribution from Norway. Five UNESCO training workshops, including three
foundation courses and two advanced training courses, took place at the regional training centre on
UCH in Chanthaburi, Thailand. The workshops all together trained nearly 100 underwater
archaeologists from over 15 countries in Asia (UNESCO 2013b). Building on the training
workshops, UNESCO further published the Training Manual for the Foundation Course on the
Protection and Management of Underwater Cultural Heritage in Asia and the Pacific in 2012, to
facilitate the development of capacity building programmes in underwater archaeology for the region
(UNESCO 2012).
At the same time, UNESCO organized regional policy meetings (Ko Kong, Cambodia in 2012,
Indonesia in 2017 and 2019 in cooperation with ASEAN) to gain support for the 2001 Convention
1

�and enhance its ratification in the region. Several large-scale conferences were also undertaken at
the initiatives of governments, universities and non-governmental stakeholders, including the
Asia-Pacific Conference on Underwater Cultural Heritage (APCONF) in Manilla (2011), Honolulu
(2014), Hong Kong (2017), and Taiwan (2020) which provided a regional platform for academic
exchange and information dissemination regarding underwater archaeology and UCH (Kimura and
McCann 2019).
While the 2001 Convention has progressively gained its influence and recognition as the
international scientific standard and effective legal instrument for UCH protection, its ratification in
Asia-Pacific remains the smallest among all regions, with only four countries1 having ratified the
Convention. In Southeast Asia, only one state, Cambodia, has ratified the Convention in 2007.

In the Pacific, two countries, Federated States of Micronesia (FSM) and Niue, have ratified the
Convention respectively in 2018 and 2019. Moreover, UCH in the Pacific has begun to gain
attention and has been increasingly integrated in the regional policies and initiatives such as the
Small Island Developing States (SIDS) Accelerated Modalities of Action (SAMOA) Pathway,
Climate Change, Disaster Resilience and Environmental Protection of the United Nation Pacific
Strategy 2018–2022, and the Regional Culture Strategy: Investing in Pacific Cultures 2010–2020.
With numerous unexplored submerged sites, ranging from sunken villages, prehistorical dwellings to
the shipwrecks from World War II, UCH is increasingly researched and recognised as a driver for
sustainable development and as an effective means for community engagement and economic
incentive through tourism (UNESCO 2017). In September 2014, UNESCO organized a side event on
Underwater Cultural Heritage and Small Island Developing States (SIDS) during the SIDS
Conference. It published two publications related to UCH in Oceania (2010) and related legislation
and programmes in the five countries in Micronesia (2018) in collaboration with UCH experts from
the region. The recent ratification of FSM and Niue is likely to be followed by other Pacific states,
including Australia currently working toward the ratification3 and potentially the Solomon Islands
and the Republic of the Marshall Islands for which UNESCO carried out studies on the gap analysis
between their national legislations and the 2001 Convention in 2021, the preparatory work towards
the ratification.

�In Asia where a series of trainings and workshops were conducted between 2009 and 2011, no other
states have joined the Convention since Cambodia’s ratification in 2007. To take stock of the
development and progress made to safeguard UCH in the region, UNESCO held a meeting in
Jakarta, Indonesia in 2019 in cooperation with the ASEAN Secretariat inviting the representatives
and experts of eight Southeast Asian countries (Brunei, Cambodia, Indonesia, Laos, Malaysia,
Myanmar, Thailand and Vietnam)4. Most underwater archaeology experts at the meeting, notably
from Cambodia, Indonesia, Malaysia and Thailand, were the beneficiaries of the UNESCO trainings
conducted between 2009 and 2011. During the meeting, the national reports on the status of
safeguarding UCH were presented by the country representatives, which clearly showed that some
progress have been made in the region to fight against commercial exploitation through various
measures, e.g. the adoption of national laws to ban commercial salvage or to reinforce national
capacity building and awareness-raising activities of the submerged cultural heritage (UNESCO
2019c). For example, underwater heritage is part of the policy for integrated coastal zone
management in Indonesia today, and since 2010, the country has stopped UCH salvaging activities
by imposing a moratorium on Ministerial Decree No. 30/200013 which permits commercial salvage
of UCH in the country.5 A marine heritage gallery is permanently held inside the Ministry of Marine
Affairs and Fisheries of Indonesia, open to the public and used for awareness-raising seminars and
activities. In Thailand, the Underwater Archaeology Division of the Fine Arts Department in the
Ministry of Culture, established in 1974, systematically undertakes a series of underwater
archaeological surveys according to proper scientific and archaeological standards. The Southeast
Asian Ministers of Education Organization, with its Regional Centre for Archaeology and the Fine
Arts (SEAMEO-SPAFA) in Bangkok, Thailand, has been actively promoting regional cooperation in
underwater protection and archaeology and organising technical and policy workshops on UCH
issues. Malaysia introduced three legislations affecting UCH, i.e. Merchant Shipping Ordinance
1952, Antiquities Act of 1976 and National Heritage Act 2005. The 2005 National Heritage Act
defines underwater heritage and authorises the Heritage Commissioner to regulate salvage or
excavation activities. In Vietnam where a great number of UCH was commercially salvaged and
most archaeological sites had been seriously damaged and deformed over the years, the government
has established the Department of Underwater Archaeology in 2013, which was later changed to the
Centre of Underwater Archaeology at the Institute of Archaeology in 2016 to enhance its capacity in
underwater archaeology and management of submerged historical sites. The Vietnamese government
officials are more conscious of the historical and cultural value of its UCH (Dissanayake 2014).
While certain positive developments to protect UCH have been observed and the national legislative
measures to halt commercial exploitation have begun to be put in place, there still remains many
challenges to overcome in Southeast Asia. Despite the increasing recognition of the importance and
the potential attached to this heritage in recent years, there is the general absence of political will and
adequate financial support to research and protect UCH in the region. Many countries still lack the
capacity and expertise to undertake systematic research on their own with the exception of a few
countries that have adequately trained national underwater archaeologists such as Thailand,
Indonesia and the Philippines, albeit with limited financial means. Lacking funding and expertise,
certain countries have also chosen to work with commercial salvage companies to carry out
archaeological research and excavation in exchange for a share of recovered artefacts, which are then
distributed to the commercial companies and eventually to auction sales. There are also issues with
legal legislation and law enforcement which are not always strictly applied in practice, leaving room
for unlicensed excavation and commercial exploitation. Even today, 15th century Vietnamese
ceramics from the Hoi An shipwreck or 19th century Chinese porcelain bowls from the Tek Sing
shipwreck can be purchased through commercial websites. In the southern coast of Cambodia, a man
was arrested in 2020 for illegally collecting and possessing some 281 ancient jars recovered from the
sea. In Vietnam, many artefacts were clandestinely recovered from the 7th to 8th century Châu Tân

�shipwreck and kept by a private collector (Kimura 2016). Low visibility of this heritage and the lack
of public awareness and ethical conscience are also factors to overcome while more
awareness-raising efforts are generally necessary at local and national levels to gain public support
to safeguard this heritage for future generations.
Future course of action
During the past decade, Latin America and the Caribbean, which possesses extremely rich
underwater cultural heritage as Asia-Pacific, had continuously suffered from commercial
exploitation and destruction of the heritage by treasure hunters. However, the region today has been
most successful in the ratification and implementation of the 2001 Convention with reinforced
human capacity and infrastructure, owing to growing awareness and efforts made by states to
enhance the regional collaboration and adopt a roadmap to prioritize the protection of underwater
cultural heritage through the ratification of the 2001 Convention (UNESCO 2015).
As such, many courses of action can be envisaged and should be reinforced in line with the
principles and rules contained in the 2001 Convention. To protect and establish a good management
of underwater cultural heritage in Asia, the provision of adequate trained underwater heritage
specialists are prerequisite. It will further help the establishment of competent national authorities,
establishment of national research agenda and national inventories, public awareness raising and
development of solid research and training programmes. To ensure the long-term preservation and
use of this heritage, the elaboration of the national need assessments and capacity building strategies
should be elaborate. In this vein, UNESCO launched a series of new initiatives, including the first
Regional Meeting on the protection of the underwater cultural heritage and the UNESCO 2001
Convention in Central Asia and the Caspian Sea Region. The meeting took place in Almaty,
Kazakhstan, participated by the representatives of 8 countries (Armenia, Azerbaijan, Georgia,
Kazakhstan, Kyrgyzstan, Russian Federation, Tajikistan, and Uzbekistan) which highlighted the
existing potential of the cultural heritage in the region. Following the recommendations of the
meeting, a “Capacity Building Strategy” was developed for the region with an aim to help develop
the necessary skills and knowledge for researching and managing the underwater archaeological
sites found in the region. As a follow-up to the Almaty meeting in 2019, national policy
consultations took place in 2021 with Kazakhstan, Kyrgyzstan, Mongolia, Tajikistan, and Uzbekistan
on the legal framework of the 2001 Convention. In cooperation with the International Centre for
Underwater Archaeology in Zadar, Croatia, technical workshops were organized for the Central
Asian countries in May and September 2023, to help states develop their capacity in underwater
archaeology and conservation and restoration of underwater archaeological finds.
In Southeast Asia, a training workshop on conservation and restoration of underwater archaeological
finds took place in June 2023, attended by heritage experts from ASEAN countries. This workshop
was realized thanks to the first tripartite collaboration among UNESCO, SEAMEO Regional Centre
for Archaeology and the Fine Arts (SEAMEO-SPAFA) and Underwater Archaeological Division
(UAD) of the Fine Arts Department, Thai Ministry of Culture. This model of regional and
international cooperation should be further reinforced to develop capacity and raise experts in
underwater cultural heritage. With huge potential for development with underwater cultural heritage
and as seen in the case of Latin America and the Caribbean, Asia-Pacific states further invest in the
UCH protection, develop regional cooperation and adopt a roadmap to prioritize its protection and
the ratification of the 2001 Convention.
In recent years, the contribution of UCH to sustainable development began to be underlined in the
Development Agenda, such as the 2030 Sustainable Development Goals (SDG), in particular SDG
14 setting up ten targets to conserve and sustainably use the oceans, and the UN Decade of Ocean
Science (2021-2030). To better respond to the emerging global challenges and safeguarding UCH
for future generations, it is about time that UCH protection should be prioritized in the national
agenda of the Asian-Pacific countries with the legal framework provided by the 2001 Convention.
