While still a young artist, Trometta moved to Rome, where he trained in the workshop of the Zuccaro brothers. He was particularly influenced by the work of Taddeo Zuccaro (1529-1566) and, along with Cesare Nebbia (c. 1536-1614), rose to become one of the workshop's principal members. He had acquired independence by 1565, when he received the commission to decorate a Chapel in S. Maria della Consolazione. Also in Rome, between 1566 and 1568, he frescoed the vault of the choir of S. Maria in Aracoeli, the centre of which comprises an oval depicting the Virgin and Child with Angels. Around 1570, he returned to his native Pesaro, where he executed numerous large-scale altarpieces that reflect the influence of Federico Barocci (c. 1535-1612). Here he remained for about a decade, before moving back to Rome around 1580. During the first half of the 1590s he decorated two chapels in S. Maria dell'Orto but, thereafter, the standard of his work declined (Turner, N.: From Michelangelo to Annibale Carracci. A century of Italian drawings from the Prado, Art Services International-Museo Nacional del Prado, 2008, p. 134).
