The frescoes in the old cathedral, dated to the 16th and 17th centuries, are mainly works of the artist Antonios and the monk Theofanis, while the dome and triangular spheres were painted in the 19th century. Furthermore, a small section of the original painting of the central nave dated to about 1280 has survived, while an important place on the north side is occupied by the fresco of St Georgios, with his rare designation as ‘Dysuritis’. According to Monastery tradition, this attribution is connected with his relationship (described below) with the therapy for that condition.
