Russian icon painter Andrei Rublev, a monk at the monastery of Trinity-Sergeyev near Moscow and at the Andronikov monastery in Moscow who began his career as an artist under the influence of Theophanes the Greek, develops his craft during a time of growing confidence and optimism in Moscow.

Although trained by Theophanes in the Eastern Roman (Byzantine) tradition, Rublev imparts to his icons a softer, more humanistic quality than those of Theophanes or other painters of the time.

His most famous icon, “The Old Testament Trinity,” painted in 1411, in which three angels, rendered in delicate curves, appear against a simple gold background, exemplifies Rublev's graceful, elegant, and singularly spiritual style, characterized by flowing outline and pure, deep color.
