Phoenix and dragon motifs were popular during the Ilkhanid period and adorned important monuments such as Takht-i Sulaiman, the summer palace of the Mongol Ilkhan, Abaka, constructed in the 1270s. Such motifs represented new iconographic references to power through their association with luxury textiles and ceramics from China from which they derived.

A star tile with a similar design, featuring a phoenix in full flight, is in the University of Michigan Museum of Art (inv no. 1960/1.132).
