On January 29, the Episcopal Church celebrates the Feast Day of Andrei Rublev (approx. 1365-1430), a Russian monk and iconographer, generally considered to be the greatest medieval Russian painter of icons and frescoes.
While still very young, Rublev entered Holy Trinity monastery in the town of Sergiyev Posad, near Moscow. Then, according to A Great Cloud of Witnesses, in 1405 he transferred to the Spaso-Andronikov monastery in Moscow, where he began studying iconography.
