Based on the interpretations of Solinus and Munster, this Ptolemaic map covers the region roughly of Thailand and Malaysia. An oddly shaped (Malaysian?) peninsula lies to the east of the Ganges River, then the China Sea (Sinus Magnus) and another landmass lies to the east of that. This depiction embodies the legacy of Ptolemy's idea of a landlocked Indian Ocean. This is the fourth edition by Girolamo Ruscelli, published by the heirs of Melchior Sessa, and edited by Giuseppe Rosaccio. Italian text on verso.
