Italian painter, born at Florence; left an orphan, was brought up in a monastery, where his talent for art was developed and encouraged; went to Ancona, was carried off by pirates, but procured his release by his skill in drawing, and returning to Italy practised his art in Florence and elsewhere, till one day he eloped with a novice in a nunnery who sat to him for a Madonna, by whom he became the father of a son no less famous than himself; he prosecuted his art amid poverty with zeal and success to the last; distinguished by Ruskin (Fors xxiv. 4) as the only monk who ever did good painter's work; he had Botticelli for a pupil (1412-1469).
