Saint Jean Baptiste, saint Antoine de Padoue et le donateur, Bonifazio Lupi

Tommaso del Mazza was a Florentine painter active in the late fourteenth century, known for refined devotional panels influenced by the Cione workshop tradition. This panel depicting Saint John the Baptist, Saint Anthony of Padua, and the donor Bonifazio Lupi is a significant commission, as Lupi was a powerful Paduan condottiere and patron who funded major artistic projects including the Chapel of San Giacomo in the Santo in Padua. The inclusion of the kneeling donor portrait reflects the growing practice of elite self-representation in religious art.

Painted in egg tempera on gold-ground panel, the composition juxtaposes the standing saints at full scale with the smaller kneeling donor figure in the conventional hierarchical arrangement of Gothic donor portraits. Tommaso del Mazza's refined technique shows careful attention to textile patterns and the individualized features of the portrait.
