This composition, with three figures seated on the near side of the table, is unusual in fifteenth century Florentine representations of The Last Supper. It was more customary to isolate Judas on the near side, as seen in Castagno's fresco of the same subject in S. Apollonia, Florence. This painting was originally part of a predella panel, a narrow horizontal band below the main panels of an altarpiece usually decorated with small narrative scenes. The scenes form this predella may have been painted by the young Francesco Botticini (1446-1497) in Castagno’s workshop.
