Only around 30 people are allowed to view the Last Supper for 15 minutes in the refectory of the Santa Maria delle Grazie monastery in Milan.
From left (heads): Bartholomew, James the Younger, Andrew, Judas Iscariot, Peter (Simon), John, Jesus Christ, Thomas, James the Older, Philip, Matthew, Judas Thaddeus, Simon Zealotes.
Note: Judas Iscariot leans back so his head is to the left of Peter. Judas, the only disciple facing away from the viewer, carries a bag of money in his hand, while Peter has a knife rather awkwardly in his hand behind Judas’ back.
Note the knot in the tablecloth on the far right. It is a wordplay on Italian for knot — il vincolo — and Da Vinci’s name. Such knots appear in several of Leonardo’s paintings and he might have thought of it as a signature or trade mark.
