Discovery of a 1,500-Year-Old Stepped Reservoir

  • The Archaeological Survey of India (ASI) has uncovered a T-shaped stepped reservoir on Elephanta Island, located off the coast of Mumbai.
  • The structure dates back approximately 1,500 years (circa 6th century CE) and was built to efficiently capture and store monsoon runoff in the island’s rocky terrain.
  • It features 20 precisely aligned stone steps made from stone blocks transported from the mainland, indicating advanced engineering and planning in ancient water conservation.

Numismatic Evidence and Political Context

  • Around 60 coins were recovered, including those made of copper, lead, and silver.
  • Several copper coins belong to Krishnaraja of the Kalachuri dynasty (6th century CE), identified by:
  • Obverse: Seated bull motif
  • Reverse: Temple symbol with the legend Sri Krishnaraja
  • These findings help establish the political and chronological context of the site during the Early Medieval period.

Evidence of Long-Distance Maritime Trade

  • Excavations revealed about 3,000 amphorae sherds of Mediterranean origin, used for transporting wine, oil, and other goods.
  • Also found were torpedo jars originating from West Asia, including regions like Mesopotamia.
  • These artifacts confirm that Elephanta Island was part of active maritime trade networks connecting India with Rome and West Asia as early as the 2nd century CE.
  • The island likely served as a transit point in the Indian Ocean trade routes.

Industrial and Cultural Artifacts

  • A brick structure believed to be a dyeing vat was discovered, suggesting textile processing as an economic activity.
  • Other finds include:
  • Terracotta figurines
  • Glass and stone bangles
  • Carnelian and quartz beads
  • These reflect craft production, cultural practices, and aesthetic sensibilities of the time.

Historical Geography of Elephanta Island

  • Historically, the island had three port localities:
  1. Morabandar
  2. Rajbandar
  3. Shethbandar
  • This highlights its role as a major maritime trading hub during the Early Historic period.

Existing Heritage Significance

  • Elephanta Island is already a UNESCO World Heritage Site due to the Elephanta Caves.
  • The caves, dating to the 5th century CE, are rock-cut temples dedicated to Lord Shiva, featuring monumental sculptures like the Trimurti.
  • The new discoveries add a socio-economic and infrastructural dimension to the site, showing it was not just a religious center but also a thriving trade and industrial node.

Significance for Indian Heritage and Archaeology

  • The findings underscore the integration of religious, economic, and technological aspects in ancient Indian urban centers.
  • They highlight the sophisticated water management systems used in rocky island environments.
  • Reinforces the importance of coastal archaeology in understanding India’s maritime history.
  • Supports historical accounts of India’s extensive trade links with the Roman Empire and West Asia.
