History of Fishing and Sailing Communities in the Western Indian Ocean
Archaeologically, the presence of fishing groups is attested in the coastal areas of the western Indian Ocean as early as the seventh millennium bce. A history of these groups shows that they diversified into sailing, trading, pearling, and other occupations over time. By the third and second millennium bce, there is evidence for the use of certain varieties of fish for ornamentation and religious offerings, especially in the Harappan culture of the Indus valley. By the early centuries of the Common Era, a complex relationship developed between several occupational groups involved in fishing and sailing, such as shipbuilders, sailors, merchants, fishermen, and religious personnel, and this is evident from the connections that these coastal groups forged with those located inland as well as those based across the seas. Sailing across the seas involved sharing of knowledge not only of wind systems and navigation but also of boatbuilding and means of identifying different regions of the coast. In this, coastal shrines played a dual role. They functioned as markers to orient sailing vessels, but more importantly were centers of worship that brought together both inland and coastal communities.
