the information about al idrisi
Answers
Al-Idrisi was born in Ceuta in Morocco, a descendant of the sharifian Hammudid dynasty, which had ruled over Málaga until 1057 and over Ceuta and Tangier until 1084. He studied at Cordova, the center of scholarship in Moslem Spain. In his youth he traveled widely, visiting Asia Minor, North Africa, Spain, France, and probably the English coast. At the invitation of Roger II, Norman king of Sicily, he went, not later than 1144, to live at the latter's court in Palermo. Roger's motives in inviting him may have been partly political. Al-Idrisi, as a descendant of a dynasty ruling in Moslem Spain and North Africa, and having an intimate knowledge of these regions, must have seemed a useful tool in Roger's designs on establishing his hegemony over the western Mediterranean.
Roger also had, however, a keen theoretical interest in geography. Since 1139 he had sponsored an ambitious project for a world geography to be based on the Greek, Latin, and Arabic geographical literature as well as on contemporary reports and research. He appointed a commission to gather and sift the material. Al-Idrisi soon became its leading member and in this function developed into one of the great Arab geographers.
