Recent Developments in the Archaeology of Long-Distance Connections Across the Ancient Indian Ocean

Open access
Abraham, Shinu Anna·2023·Annual Review of Anthropology

Abstract

Scholarship on the ancient Indian Ocean, which stretches deep into the previous century, is available from an array of academic disciplines including but not limited to history, archaeology, epigraphy, numismatics, art history, and materials science. It spans from prehistory to the present era and includes evidence ranging from the Mediterranean to East Asia. What binds together the world of Indian Ocean research is an enduring interest in the complex maritime-based links crosscutting this space and—for archaeologists—the movements of cultural elements (objects, ideas, people, etc.) that have left behind some material trace. Recent field projects and materials science studies have greatly expanded this material database, refining (and sometimes challenging) traditional interpretations about Indian Ocean maritime relations. This review presents a streamlined perspective, focusing on recent archaeological contributions about long-distance interregional connections across the Indian Ocean from 500 bce to 1000 ce.

TL;DR

This review synthesizes recent archaeological and archaeometric research on long-distance maritime connections across the ancient Indian Ocean from roughly 500 BCE to 1000 CE, organized by four chronological periods and four overlapping regions centered on South Asia. It argues that new field projects and materials-science studies have expanded and sometimes overturned traditional interpretations, while anthropological theory remains largely absent from the synthesis of this material.

Key findings

  • Long-distance maritime links predate Indo-Roman trade: stratified data from Tissamaharama push Rouletted Ware (and Wheeler Types 10 and 18, grouped as Fine Gray Pottery) back to the third–second centuries BCE, supported by Rouletted Ware and Wheeler Type 18 in the earliest layers at Khor Rori (Oman) prior to the first century BCE.
  • At Berenike (Egypt), finds include a large Indian ceramic jar filled with 7.5 kg of south Indian pepper, a second-century CE 2-foot-tall Buddha statue (the first ever west of Afghanistan), two more second-century CE Satavahana coins, and a third-century CE Sanskrit inscription, alongside evidence for a settled South Asian population.
  • Pattanam (south India) has amphora sherds surpassing even Arikamedu in quantity and the largest known Indian Ocean archaeological glass bead corpus; Khao Sam Kaeo (Thailand) yielded Indian pulses (horse gram, mung), possibly South Asian cotton, and Brahmi inscriptions dated to the third–first centuries BCE.
  • South Indian/Sri Lankan Indo-Pacific glass beads circulated from the third century BCE to the tenth century CE, reaching western Europe (fifth–sixth-century CE Merovingian burials) and East Asia; Zhizo glass beads dominate the southern African assemblage until the tenth century CE and are found at more than 25 sites in Zimbabwe, Botswana, and South Africa.

Methods

  • Narrative literature review and synthesis of archaeological, archaeometric, epigraphic, numismatic, and materials-science scholarship; no new primary data are presented.
  • Scope is deliberately delimited to sites (primarily ports, transshipment points, settlements, and mortuary sites) with archaeologically visible nonlocal materials, emphasizing long-distance interregional rather than intraregional connections.
  • Organized across four chronological periods from roughly 500 BCE to 1000 CE and four overlapping regions: the South Asian subcontinent, the eastern Indian Ocean, the western Indian Ocean, and the southern Indian Ocean.

Limitations

  • The paper states that the South Asian material corpus "tends to be uneven across the subcontinent and not always systematically published," that South Asia's early medieval period is "archaeologically murky," and that southern Indian Ocean material evidence is sparse in the earlier phases.
  • The author states that the review is deliberately delimited, foregrounding fresh contributions on material connectivities and minimizing historiography, and focusing on long-distance rather than subregional links.
  • The paper itself notes a "cleavage" between gains in data and methodology and the scholarship that theorizes early Indian Ocean maritime relations, observing that anthropological theories are often engaged through "the uncritical adoption of outdated concepts and models" — a limitation of the field the review identifies rather than of the review's own method.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
