This collection is made up of reports on the work of Andrei Rublev and the art of his time, which were read by the authors on September 16-17, 1960 at a scientific session at the USSR Academy of Arts dedicated to the work of the great master on the occasion of his 600th birthday. Some reports published in special journals were not included in this collection. On the other hand, it included several articles that could not be heard at the session, as they were presented later.
