an Italian painter, was born at Rome in 1598. From his father, a mediocre artist, he received his first ideas of art, and by studying the works of Albani he became one of the best artists of the Roman school. His works show great care in execution, though they have been criticized by Raphael Mengs as lacking in detail. In the Vatican are four of his paintings, which are reproduced in Mosaic in the crypt of St. Peter's. Among his best paintings are the Miracle of St. Gregory the Great, Noah and his Sons, and portraits of Albani and of the artist himself. He died in 1661. His tomb is in the church of St. John Lateran at Rome.
