In the narthex there is a series of frescoes.
I have been informed this is probably an icon of the oecemenical council of Nicea, the man with the crown being St. Constantine the Great
Fresco with bishops and emperor in Ecumenical Council. Possibly an evocation of the First Council of Nicaea (325 AD), which St.Nicolas attended to. In that case, the emperor depicted is Constantine I (the Great); the representation corresponds to the usual Byzantine iconography of the saint emperor.
The frescos must be dated around the 12th century, since this part of the church was built in the mid-11th century, and the city of Myra was completely deserted by the early 14th century.
