In 1498, when he saw Florence's convent of San Marco stormed and its strict, charismatic prior Savonarola dragged to prison, Baccio vowed to become a monk ; he became Fra Bartolommeo in 1500. Fra Bartolommeo, Bartolommeo also spelled Bartolomeo, also called Bartolomeo della Porta or Baccio della Porta, (born March 28, 1472, Florence [Italy]—died Oct. 31, 1517, Florence), painter who was a prominent exponent in early 16th-century Florence of the High Renaissance style. Fra Bartolomeo or Bartolommeo OP (28 March 1472 – 31 October 1517), also known as Bartolommeo di Pagholo, Bartolommeo di S. Marco, and his original name Baccio della Porta, was an Italian Renaissance painter of religious subjects. A mule driver's son, the young artist born as Baccio della Porta studied with a local painter, then worked with Ghirlandaio's conservative workshop.
