Edrisi

Edrisi (1100-1180), a great Moorish geographer, who traced his descent from Mahomet. He is thought to have studied at Cordova, and travelled in Spain, Barbary, and Asia Minor, and visited the court of Roger II., king of Sicily, who employed him in geography and on a description of the earth from the reports and statistics of many travellers who were sent out to make observations. This book was completed in 1154, and has been partially and often inaccurately translated. Edrisi made a map and a celestial sphere. He also wrote upon herbs, and another work upon geography, which has disappeared.
