Domenico Zampieri (, ; October 21, 1581 – April 6, 1641), known by the diminutive Domenichino (, ) after his shortness, was an Italian Baroque painter of the Bolognese School of painters. Life Domenichino was born in Bologna, son of a shoemaker, and there initially studied under Denis Calvaert. After quarreling with Calvaert, he left to work in the Accademia degli Incamminati of the Carracci where, because of his small stature, he was nicknamed Domenichino, meaning "little Domenico" in Italian. He left Bologna for Rome in 1602 and became one of the most talented apprentices to emerge from Annibale Carracci's supervision. As a young artist in Rome he lived with his slightly older Bolognese colleagues Albani and Guido Reni, and worked alongside Lanfranco, who later would become a chief rival. In addition to assisting Annibale with completion of his frescoes in the Galleria Farnese, including A Virgin with a Unicorn (c. 1604–05), he painted three of his own frescoes in the Loggia del Giardino of the Palazzo Farnese c. 1603–04. With the support of Monsignor Giovanni Battista Agucchi, the maggiordomo to Cardinal Aldobrandini and later Gregory XV, and Giovanni's brother Cardinal Girolamo Agucchi, Domenichino obtained further commissions in Rome. His most important project of the first decade was decoration of the Cappella dei Santissimi Fondatori in the medieval basilica of the Abbey of Grottaferrata (1608–1610), some 20 kilometers outside Rome, where Odoardo Farnese was the titular abbot. Meanwhile, he had completed frescoes c. 1604–05 in the church of Sant'Onofrio, feigned stucco decoration of 1606–07 in the Palazzo Mattei, a large scene of The Flagellation of St. Andrew at San Gregorio Magno, painted in competition with a fresco by Reni that faces it, and a ceiling with Scenes from the Life of Diana, 1609, in the Villa Odescalchi at Bassano di Sutri (today Bassano Romano). Following Annibale Carracci's death in 1609, the pupils who had followed Annibale's Roman style, including Domenichino and Francesco Albani, were not as successful at gaining the most prestigious commissions as Guido Reni. As Donald Posner stated in his influential thesis, The Roman Style of Annibale Carracci and His School, ‘...it should be stressed that the severe classicism of Annibale’s late style had an immediate life in Rome of only about a lustrum [five years].’ In turn, the Bolognese biographer Malvasia states that 'only Guido [Reni] was put ahead of everyone else, Guido alone proclaimed and well
