When was this made?
Late Byzantine bowls that utilized sgraffito and were made in the later half of the 13th century, like our bowl to the right, tended to parallel early Sasanian Persian design.
Another eastern Mediterranean harpy bowl made in the year 1250, from the Victoria and Albert Museum, depicts the harpy wearing a crown that seems to be influenced by an early Sasanian motif. This motif of spreading wings was common imagery used to depict crowns on Sasanian Rulers.
