Cosmas Indicopleustes, Christian Topography

An Alexandrian merchant-turned-monk's flat-earth cosmology, with first-hand notes on the Indian Ocean trade: Christians in Taprobane, Male (Malabar), Kalliana and Socotra; the pepper vine and coconut; Indian animals (rhinoceros, musk deer); and Sielediba (Sri Lanka) as the hub between China and the West, with the story of the Roman coin shown to its king.
