- This panel is one of seven predella pictures from an altarpiece commissioned from Sassetta by Siena’s wool merchants’ guild, the Arte della Lana, in 1423. It was probably intended for the church of Santa Maria del Carmine, where Mass was celebrated at the guild’s altar on the feast of Corpus Christi. This altarpiece was dedicated to the theme of the Eucharist; here a heretic has clearly denied the orthodox theology of the true presence of Christ in the materials of the Eucharist.
