Leo Africanus

Johannes Leo Africanus (born al-Hasan Muhammad al-Wazzan al-Fasi, ; – ) was an Andalusi diplomat and author who is best known for his 1526 book ''Cosmographia et geographia de Affrica'', later published by Giovanni Battista Ramusio as ''Descrittione dell'Africa'' (''Description of Africa'') in 1550, centered on the geography of the Maghreb and Nile Valley. The book was regarded among his scholarly peers in Europe as the most authoritative treatise on the subject until the modern exploration of Africa. For this work, Leo became a household name among European geographers. He converted from Islam to Christianity and changed his name to Johannes Leo de Medicis (). Leo possibly returned to North Africa in 1528, reverting back to Islam. Provided by Wikipedia
