Court musician. Al-Mansur Al-Yahudi was court musician for the Umayyad Caliph Al-Hakam I in Cordoba, Spain in the early ninth century. An historical source from the 17th century suggests that he was instrumental in bringing the famous musician Ziryab to Cordoba in 822, thus helping to initiate 'the splendid era of Arab music in Spain inaugurated by Ziryab.'*
