Quick Revision: Underwater archaeological explorations off Poompuhar have yielded a torpedo jar fragment and ring wells, providing evidence of early historic maritime trade and palaeochannel hydrology in the region.

Why is this in the news?

The discovery of a torpedo jar fragment and ancient ring wells during the third phase of underwater archaeological exploration off the Poompuhar coast in Mayiladuthurai district, Tamil Nadu, provides significant evidence of early historic maritime trade and coastal hydrological patterns. This finding is noteworthy as it represents the first instance of such artefacts being recovered underwater in Tamil Nadu, offering insights into the region’s ancient port city, Kaveripoompattinam, and its connections with West Asian trade routes.

Background

• Poompuhar, historically known as Kaveripoompattinam, was a prominent port city during the Sangam period (300 BCE–300 CE) and served as a key hub for maritime trade between South India and regions such as Rome, Egypt, and West Asia.
• The Tamil Nadu State Department of Archaeology (TNSDA) has been conducting systematic archaeological surveys in the region to document and preserve underwater cultural heritage, particularly in light of coastal erosion and sea-level changes.
• Torpedo jars, also known as amphorae in Mediterranean contexts, were utilised for transporting liquids such as wine, oil, and perfumes due to their shape, which minimised spillage during transit.
• Ring wells, circular structures typically used for water storage or drainage, are commonly found in archaeological sites from the early historic period and provide clues about settlement patterns and hydrological conditions.
• The Poompuhar coast has been subjected to significant environmental changes, including erosion and sediment deposition, which have necessitated systematic underwater explorations to recover and document submerged cultural artefacts.

Key Aspects of the Underwater Archaeological Discoveries

• Torpedo Jar Fragment: A broken piece of a torpedo jar was recovered at a depth of 10 metres and 2 km from the Poompuhar coast. The estimated diameter of the complete torpedo jar was 30–35 cm. The fragment is made of fine ceramic and is believed to have originated from West Asia, indicating long-distance maritime trade during the early historic period.
• Maritime Trade: Torpedo jars were primarily used for transporting liquid commodities such as wine, oil, or perfumes. Their presence in Poompuhar underscores the city’s role as a major port in the Indian Ocean trade network, connecting South India with West Asia and the Mediterranean.
• Ring Wells: Four ancient ring wells, with diameters ranging from 60 cm to 65 cm, were discovered during the exploration. These structures are typically associated with water management systems and may indicate the presence of a palaeochannel, a former river or stream channel now submerged or altered by coastal processes.
• Palaeochannel Hypothesis: The discovery of ring wells suggests that a palaeochannel might have existed at the site, providing insights into the historical hydrology of the region. Such channels are often linked to the shifting courses of rivers like the Kaveri, which historically flowed through Poompuhar.
• Ceramic Assemblage: Over 250 ceramic fragments, including glazed ware, were recovered during the survey, expanding the corpus of material culture associated with Poompuhar’s maritime heritage. These artefacts contribute to the understanding of trade networks, craft production, and cultural exchanges in the region.
• Environmental Context: The findings are situated within the broader context of coastal erosion and sea-floor changes affecting Poompuhar. Systematic underwater archaeology is crucial for documenting submerged heritage before it is lost to natural processes.
• Methodology: The underwater exploration utilised advanced archaeological techniques, including systematic grid surveys and depth-based sampling, to recover artefacts while minimising disturbance to the underwater environment.
• Significance for Heritage Conservation: The discoveries highlight the importance of preserving underwater cultural heritage, particularly in regions prone to environmental degradation. Further investigations by the TNSDA are planned to contextualise these findings within the broader history of Poompuhar.

Why it Matters

Maritime Trade and Economy

• The discovery of a torpedo jar fragment, likely from West Asia, underscores Tamil Nadu’s integration into global trade networks during the early historic period (c. 300 BCE–300 CE).
• Torpedo jars were designed for efficient transport of liquids, suggesting the trade of high-value commodities like wine, oil, or perfumes, which were in demand in ancient Tamilakam.
• The presence of glazed ware among the ceramic fragments indicates advanced ceramic technology and the import of specialised goods, reflecting economic prosperity.

Historical and Archaeological Insights

• The findings corroborate historical accounts of Poompuhar (Kaveripoompattinam) as a thriving port city, mentioned in Sangam literature and early Tamil inscriptions.
• Ring wells provide evidence of ancient water management systems, suggesting organised settlements and agricultural practices near the coast.
• The palaeochannel hypothesis aligns with geological and hydrological studies of the region, offering clues to past river courses and coastal evolution.

Cultural and Technological Exchange

• The torpedo jar’s origin from West Asia highlights cross-cultural exchanges in material culture, technology, and trade practices during antiquity.
• The discovery of similar artefacts at sites like Alagankulam, Korkai, and Porpanaikottai reinforces the interconnectedness of Tamil Nadu’s port cities in the past.

Environmental and Geological Context

• The underwater exploration addresses the impact of coastal erosion and sea-level changes on submerged heritage, a critical concern for preserving India’s maritime archaeology.
• The findings contribute to understanding the dynamic relationship between human settlements and coastal geomorphology in the Bay of Bengal region.

Challenges

1. Underwater Archaeology Challenges

• Conducting archaeological surveys in submerged environments requires advanced equipment, technical expertise, and significant financial resources.
• Preservation of artefacts recovered from saline underwater conditions demands specialised conservation techniques to prevent degradation.
• Logistical challenges, including limited visibility and depth constraints, complicate the documentation and retrieval of artefacts.
