In the recent works Alexey Komech and Oleg Ioannisian consider the architecture of Pereyaslavl’ (Juzhny/Southern, or Russian), dated from the late 11th to the mid-12th century, as the continuous process and even an architectural school. Earlier in 1980s, Pavel Rappoport in his latest works firmly divided the Pereyaslavl’ buildings into two groups, erected separately by metropolitan Efrem and Prince Vladimir Monomach in the late 11th century, and by the Kievan builders in the mid-12th century. Th is concept was based on the considerable differences in the constructional and stylistic features of the monuments. The research on the bricks carried out by
the author has provided new evidence for Rappoport’s concept. After the latter, the Pereyaslavl’ builders workshop had been consolidated under the direction of a Byzantine architect in the course of the building program of the metropolitan Efrem and existed no longer than 3 decades, exerting almost no infl uence on the architecture of the neighboring Russian principalities. The author calls in question the validity of the concept of “architectural school” in this specific case.
