The only work authenticated as entirely his is the icon of the Trinity, ca. 1410, currently in the Tretyakov Gallery, Moscow. It is based upon an earlier icon known as the "Hospitality of Abraham". Rublyov removed the figures of Abraham and Sarah from the scene, and through a subtle use of composition and symbolism changed the subject to focus on the Mystery of the Trinity.
Andrei Rublyov was canonized a saint in 1988 by the Russian Orthodox Church. The church celebrates his feast day on January 29.
In 1966, Andrei Tarkovsky made his celebrated film "Andrei Rublyov" loosely based on the artist's life, which shows him as "a world-historic figure" and "Christianity as an axiom of Russia's historical identity" during a turbulent period in the history of Russia.
