William II of Sicily
Ibn Jubayr provides a highly-detailed and graphic description of the places he visited during his travels. The book differs from other contemporary accounts in not being a mere collection of toponyms and descriptions of monuments but containing observation of geographical details as well as cultural, religious and political matters. Particularly interesting are his notes about the declining faith of his fellow Muslims in Palermo after the recent Norman conquest and about what he perceived as the Muslim-influenced customs of King William II of Sicily under the Norman-Arab-Byzantine culture.
