This paper traces the impact of Roman-Byzantine loot on Umayyad art through close analysis of two seventh- and eighth-century tents: one described in al-Tabari’s chronicles of the early Arab-Muslim conquests, and the other painted on the walls of an early eighth-century bathhouse in Jordan. In the aftermath of a battle between Arab-Muslim and Byzantine forces in the year 644, an Arab woman known as Umm Abdallah bint Yazid al-Kalbiyya received a tent as loot. The tent had previously belonged to a Byzantine commander named Maurianos (al-Mawriyan al-Rumi), whom Umm ?Abdall?h had helped defeat. Although Umm Abdallah won her tent almost twenty years before the Umayyad family secured their hold on the caliphate, the anecdote reveals the kind of objects that were acquired as loot during the Arab-Muslim conquests of Roman-Byzantine territories that continued well into the Umayyad era. No depictions of Umm Abdallah’s tent survive, but this textual tent has a visual counterpart in the form of a tent depicted among the murals of a bathhouse decorated for the prince al-Walid ibn Yazid before he ascended to the throne in 743. The use of Roman-Byzantine pictorial conventions throughout the murals, like Umm Abdallah’s tent, indexed the successful Umayyad appropriation of Roman-Byzantine materials and images. When considered in light of early Arabic anecdotes describing Roman-Byzantine imperial tents and other loot acquired during the Arab-Muslim conquests, Umm Abdallah’s prize tent and al-Walid’s painted tent at Qusayr ‘Amra demonstrate the important roles that Roman-Byzantine loot played in the formation of Umayyad imperial visual culture.
