One of several frescoes in what I think was a kind of corridor or outer aisle, numbered 11 on the ground plan.

I have been informed this photo is of the Archangel Gabriel as he is depicted in the icon of the Annunciation.

Byzantine fresco from the 12th century.

The icon of the ‘Annuciation’ refers to the Gospel (Luke 1:26-39): the announcement by the angel Gabriel to the Virgin Mary that she would conceive and become the mother of Jesus, the Son of God.
