Parts of a panel found at the Kalenderhane Mosque, late 6th, early 7th century. Representing the Hypapanthe. That, I understand, is the meeting (hypapante) of the Christ Child and his Mother with the holy Simeon and Anna in the Temple.
For any use: see my Profile. NOTE: Many of my pictures are in sub-galleries (some within another, their name is in bold print)!
