Focus on San Pietro Martire Triptych and discuss the Description.
In the center of the work is a Maestà (Madonna Enthroned with Child) and, at the sides, are the Saints Dominic, John the Baptist, Peter of Verona, and Thomas Aquinas. In the cusps are lobed tondoes with the Annunciation Angel, the Annunciation and, in the center, Blessing Christ. Between the cusps are scenes of the life of St. Peter of Verona (Predication and Martyrdom).
The Madonna sits on a brocaded seat, with the Child standing on her knees. She is holding an ampulla, a reference to Mary Magdalene's ampulla and thus to Jesus' passion. The Child wears a tunic with rich golden decoration. His hand holds a globe, a symbol of his power, while the other hands is raised in a blessing gesture. The relative lack of decoration, compared to Angelico's earlier Fiesole Altarpiece (1424–1425), which was still heavily based on Gentile da Fabriano's style, show the growing influence of Masaccio and a more realistic approach.
