In the 18th century the medallion was thought to depict a portrait of Galla Placidia with her children. However modern scholars have firmly rejected this identification. https://www.jstor.org/pss/3046553.
Inscriptions on the medallion are not personal names; they have instead been identified as words in the Greek dialect of Alexandria, Egypt, which was then a Roman province.
