Similarly, the archaeological findings from Harappa, Mohenjo-Daro and Lothal suggest that maritime trade existed between the Mesopotamian and Indus Valley Civilisations. “Undoubtedly, people of the Indus Valley Civilisation sailed across the Arabian Sea,” according to Tripati.The Harappan seal recovered from excavations depicts a ship with mast and sail, while a seal and a terracotta amulet from Mohenjo-Daro depict a ship with cabin and birds. Clay model boats have been found from Lothal excavations.
