The archaeological excavations of the Rusokastro fortress have revealed an extremely rare and elite find. During the excavation was founded a two-sided icon of ivory with a facial image of archangel Gabriel and St. Basil the Great. On the reverse side are depicted two crosses - the crown cross and the procession cross. The images are part of the Annunciation scene.
Essentially, the find is a triptych wing. It was threefold and was used as a traveling altar.
The find was made in the 10th century in Constantinople by order of some one of the Byzantine emperors or of a member of the imperial family.
