Focus on this artwork and explain the abstract.
The Painting of the Six Kings is a fresco found on the wall of Qasr Amra, a desert castle of the Umayyad Caliphate located in modern-day Jordan. It depicts six rulers standing in two rows of three. Four of the six have inscriptions in Arabic and Greek identifying them as the Byzantine emperor, King Roderic of Spain, the Sasanian emperor, and the King of Aksum. The painting, now substantially damaged, is thought to be from between 710 and 750, commissioned by the Umayyad caliph or someone in his family. It is one of the most famous frescoes in the Qasr Amra complex.
