Abstract

By the fourth/tenth century, Egypt's Nile Delta had just two major Delta branches debouching directly into the Mediterranean – the Dumyā (Damietta) and Rashīd (Rosetta). Navigational conditions at these branches’ mouths were treacherous because of a combination of currents, winds, wave-fields and shifting sandbanks. These conditions were a danger to shipping, and so had a formative effect on the navigational landscape of the Delta. Despite its remoteness from the Nile, Alexandria remained Egypt's chief Mediterranean port, but only because river connections were maintained that avoided the Rashīd mouth. In contrast, the port of Rashīd was relatively insignificant. Similar conditions at the Dumyā mouth prompted navigators to adopt routes via Lake Tinnīs, modern Lake Manzala, which linked to the sea through its calmer sea mouths. This article brings together material from multiple disciplines to offer a new understanding of the navigational context of Egypt's medieval Mediterranean ports.
