Illuminated Manuscript, Maritime atlas, Walters Art Museum Ms. W.660, fol.3a

This is an illuminated and illustrated maritime atlas, referred to as the Walters Deniz atlası. It is an early Ottoman atlas, perhaps dating to the tenth century AH / sixteenth CE. The work contains eight double-page charts executed on parchment. Four of the maps show the Mediterranean, Aegean, and Black seas. There is also a world map and a chart of the Indian Ocean. The various geographical names are written in black nastaʿlīq script. A distinguishing feature of this atlas is the detailed approach to representing such features as city vignettes. East Africa and the Arabian Peninsula.
