I've never seen this one before.
It was entitled "Love".
It could be misleading to the casual onlooker, who doesn't know to read the letters identifying the Theotokos.
It is a copy of a triptych panel by the early Renaissance master Cimabue, and it represents the assumption of the Virgin. Other painters of the era painted similar compositions, with some showing both Christ and the Virgin seated on the same heavenly throne.
Here is Cimabue's work:
In reply to Liza's comment, even if an observer could identify the woman as the Mother of God, this image is still, erm, problematic from the Orthodox POV. The bodily assumption of the Mother of God after her death is accepted and mentioned, but not elaborated upon, in hymns and teachings. It is a mystery, and one which iconography has never portrayed, unlike non-Orthodox religious art.
What Orthodox iconography does show, and rightly so, is Christ mystically appearing at His Mother's dormition. He is surrounded by a mandorla of uncreated light in which are numerous seraphim, and He is holding the soul of His Mother, as a babe in swaddling-clothes. This beautifully and eloquently expresses the incomparable honor of the Virgin - as she gave birth and nurtured her Son and God, the Life of all, so He received her soul to escort it to heaven Himself, she being more honorable and more glorious than the hosts on high
, as the hymn says. Allowing a "mere" angel to take her soul just would not do. The hymns of the Dormition must surely be the loveliest and most evocative of all the feasts of the Mother of God.
In Cimabue's painting, and its variants, while the Virgin is in a supplicatory posture, she is still seated at the same level as Christ. In iconographic deesis (supplicatory) panels which show Christ enthroned at the center, flanked by the Virgin and St John the Baptist (and others, in many cases), only Christ is enthroned. The Mother of God is indeed the most powerful of intercessors, but she is not, and never can be, equal to God. She was graced with divinity in the fullest sense, but she is not divine herself.
