Umayyad or Abbasid Ivory Plaque, mid-8th century AD, Humaymah, Jordan

A partially burned ivory plaque, found in the ruins of the early Islamic settlement at Humaymah in southern Jordan, dates from the mid-8th century AD. It was probably made in eastern Iran. Humaymah was inhabited by members of the 'Abbasid family before their supporters rose in revolt against the ruling Umayyad Caliphs in the eastern Iranian region of Khurasan. (J. P. Oleson photograph)
