Generally acknowledged as Russias greatest iconographer, Andrei Rublev was born around 1365 near Moscow. While very young he entered the monastery of The Holy Trinity and in 1405, with the blessing of his igumen (the Orthodox equivalent of abbot), he transferred to the Spaso-Andronikov monastery where he received the tonsure and studied iconography with Theophanes the Greek and the monk Daniel. Among his most revered works are those in the Dormition Cathedral in Vladimir.
