“The Last Supper”, fresco (453 × 975 cm) by Andrea del Castagno, about 1447, preserved on the west wall of the refectory of the monastery of Sant'Apollonia in Florence, now the museum of the Cenacle of Sant'Apollonia. Detail with Jesus in the centre and Saint John, sitting at his side, bending his head towards his chest and leaning on the table, visibly asleep. From behind is Judas Iscariot, sitting on a stool which rests (not by chance) below the platform, he is the only one to occupy the opposite side of the table and is alone in front of Jesus. The positioning of Judas separated from the rest of the apostles it is typical of this iconographic theme (although it is usually found on the right rather than the left of Christ). His figure, without a halo, with black hair, a dark beard, a penetrating gaze and a hooked nose, resembles that of a satyr from Roman mythology, from which the Christians had borrowed many of the physical characteristics of the devil.
