Andrei Rublev (c. 1360–1430) was a celebrated Russian medieval painter of Orthodox Christian icons and frescoes, now revered as a saint with a feast day on 29 January. His career began in 1405 when he decorated Moscow's Cathedral of the Annunciation alongside Theophanes the Greek, and he later painted major works in Vladimir (1408) and the Trinity Lavra (1425–1427). His only authenticated surviving work is the Trinity icon (c. 1410), which masterfully refocused the biblical scene to symbolize the Mystery of the Trinity. Combining strict asceticism with Byzantine harmony, his style became the official model for church painting after 1551 and heavily influenced later artists like Dionisy. Dying between 1427 and 1430, Rublev was canonized by the Russian Orthodox Church in 1988, and his legacy extends to the Andrei Rublev Museum and Andrei Tarkovsky's 1966 biographical film. A notable recent event is the return of the Trinity icon to the Holy Trinity Lavra in June 2024, where it was reinstalled in its original position.
