This Brancacci Chapel of the Carmine plays the same part in the history of painting as the bronze gates of the Baptistery in that of sculpture. It was in that same eventful year, 1401, of the famous competition between Ghiberti and Brunelleschi, that the new Giotto was born--Tommaso, the son of a notary in Castello San Giovanni di Valdarno. With him, as we saw in chapter iii., the second great epoch of Italian painting, the Quattrocento, or Epoch of Character, opens. His was a rare and piquant personality; _persona astrattissima e molto a caso_, says Vasari, "an absent-minded fellow and very casual." Intent upon his art, he took no care of himself and thought nothing of the ordinary needs and affairs of the world, though always ready to do others a good turn. From his general negligence and untidiness, he was nicknamed _Masaccio_--"hulking Tom"--which has become one of the most honourable names in the history of art. The little chapel in which we now stand and survey his handiwork, or what remains of it, is nothing less than the birthplace of modern painting. Sculpture had indeed preceded painting in its return to nature and in its direct study of the human form, and the influence of Donatello lies as strongly over all the painters of the Quattrocento. Vasari even states that Masolino da Panicale (Masolino = "dear little Tom"), Masaccio's master, had been one of Ghiberti's assistants in the casting of the bronze gates, but this is questionable; it is possible that he had been Ghiberti's pupil, though he learned the principles of painting from Gherardo Starnina, one of the last artists of the Trecento. It was shortly after 1422 that Masolino commenced this great series of frescoes setting forth the life of St. Peter; within the next few years Masaccio continued his work; and, more than half a century later, in 1484, Filippino Lippi took it up where Masaccio had left off, and completed the series.
