Albertinelli, Mariotto, an Italian painter, was born at Florence in 1475. He is said to have been the disciple and friend of Fra Bartolomeo di San Marco, whose style he followed, and whose merit he nearly approached. He was of a very jealous and unhappy disposition. Once, upon hearing an unfavorable criticism on his work, he abandoned the art for some time, but returned to it some years after. His works are almost wholly upon sacred subjects. Several of them are in the churches and convents of Rome, Florence, and Viterbo. In the Church of San Silvestro a Monte Cavallo is a picture by him of The Virgin and Infant on the Throne, with S. Domenico and S. Catterina da Siena. lie died in 1520.
