In 1154, Muhammad al-Idrisi completed a collection of maps of the lands known to medieval Arabic and European scholars. This collection was titled Al-Kitāb al-Rujārī (The Book of Roger), after the Norman king Roger II who hired him to create it. To create the collection, al-Idrisi consulted Arabic and Greek maps and interviewed travelers about the lands they visited. He included these travelers’ stories alongside the map illustrations.
