Abu Abd Allah Muhammad al-Idrisi (1100–1165 or 1166) was an Arab cartographer, geographer and traveller who lived in Sicily, at the court of King Roger II. Muhammad al-Idrisi was born in Ceuta and died in Sicily, or maybe in Ceuta. Al Idrisi claimed that he was a direct descendant of the prophet Muhammad.
Al-Idrisi's best known work is his map of the world "lawh al-tarsim" (plank of draught), of 1154. He worked on the commentaries and illustrations for eighteen years at the court of King Roger II of Sicily. His map is now known as the 'Tabula Rogeriana', his book as the Geografia. His maps were used extensively during the explorations of the era of the Renaissance like the journeys of Christopher Columbus.
