The study investigates the appearance and further development of architectural orders in the major Greek colonies in the North Pontus, especially in the main cities Tyras, Olbia, Chersonesos and Pantikapaion. Special attention is paid to the question of the local architectural schools and the stylistic influences first from southern Ionia, primarily Miletus, later on from Attica as well as Asia Minor and finally from Italian workshops. It is proved that in the first centuries A.D. the North Pontic littoral became closely connected with the imperial marble trade from Prokonnesos Island via the Black Sea, bringing to an end the local architectural tradition.
