This article discusses the map of the Tigris and Euphrates in the private collection of Shaikh Hassan bin Muhammad al-Thani of Qatar. Through a detailed comparison of the map with the text of Evliya Celebi's (1611-c.1685) Seyahatname (Book of Travels), this study demonstrates that the map in question was drawn up either by Evliya himself or else by someone in his retinue and under his supervision.
