When was this made?
This green ceramic harpy bowl was made around the year 1250.
Another eastern Mediterranean harpy bowl made around the same time, from the Victoria and Albert Museum, depicts the harpy wearing a crown that seems to be influenced by an early Sasanian traditions. The Sasanians were pre-Islamic rulers or Persia or Iran. This motif of spreading wings was common imagery used to depict crowns on Sasanian rulers.
