Византий и Византия: провинциализм столицы и столичность провинции
The question of the origin of the triconch of “Athonite type” — an inscribed cross on 4 free-standing supports with additional apses from the south and north — still causes a heated debate in the scholarship.
The purpose of this article is to draw attention to monuments of this type outside the Balkans. It is very likely that the Triconch hall and the church of the Archangel Michael, built for the Emperor Theophilos by Ioannes Grammatikos and the architect Patrikios, had probably such a plan, possibly following an Arabic model, which, in turn, goes back to the Late Antique examples. The early churches of this type in Asia Minor (Islamköy and Sarıca Kilise), dating to the early 10th century, show its common and “prestigious” character, which led to its spread not only to the Balkans, but also to Russia.
