The art of hagiography developed in the area of Northern Epirus is also amazing. The most ancient hagiographies date back in the 12th century (Virgin Mary in Boria – Korytsa). The artists follow the Byzantine style. Some of the most significant hagiographers were Onoufrios and his son Nikolaos (16th century), who worked in Temples in Berati and Kastoria. Other significant hagiographers were Onoufrios the Cypriot (17th century) and David from Selenitsa (18th century). At this point, it should be underlined that all inscriptions were written in Greek language. The unity of art in both Southern and Northern Epirus as well as in Western Macedonia proves the relation that existed between these parts of Greece.
