Andrei Rublev was a Russian icon painter. He is considered to be one of the greatest medieval Russian painters of Orthodox Christian icons and frescos. He is canonized as a Saint in the Eastern Orthodox Church, and his feast day is 29 January.

An icon is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, and Catholic churches. They are not simply artworks; "an icon is a sacred image used in religious devotion". The most common subjects include Jesus, Mary, saints, and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most of the religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints.
