LUCA, a famous Italian painter, was born at Cortona, in 1440. He was nephew to Lazzaro Vasari, and kinsman to the historian of art, Georgio Vasari. He studied art under the care of Piero della Francesca at Arezzo, where he lived with his maternal uncle Lazzaro. Few of his paintings now remain. His most celebrated work was the fresco of the "Last Judgment," in a chapel at Orvieto, which had been begun in 1447 by Fra Giovanni da Fiesole, and was completed by Signorelli probably about 1503. The execution of the naked figure in these elaborate designs has been very much admired; and Vasari says, that Michael Angelo did not refuse to make use of Signorelli's invention in his delineation of the forms of angels and demons in his grand painting of the "Last Judgment" in the Sistine chapel. He retired to his native place, where he spent the evening of his days in honour and tranquillity. He died in 1521, aged eighty-two.
