It was S. Giovanni Gualberto who founded the Vallombrosan Order and established here an abbey, whose daughter we now see. Born about the year 1000, he was the son of Gualberto dei Visdomini, Signore of Petroio in Val di Pesa, of the great family who lived in St. Peter's Gate in Florence, and were, according to Villani, the patrons of the bishopric.
It shows him as a good pure colourist, the flesh tints being especially tender; the composition is lively, full, and effective. In 1518 he painted a fine altar-piece for the church of S. Michele Visdomini, Florence, by commission of Francesco Pucci. The Madonna, seated, is showing the Child Jesus to S. Joseph, whose face is most expressive and full of smiling admiration.
