The Last Supper is like a snapshot. Something has just triggered the vast array of emotions shown by the disciples. Jesus remains calm and composed, his arms open before him. What is happening?
The instant painted by Leonardo da Vinci corresponds to verse 24 from the thirteenth chapter of John’s gospel. The disciples are reacting violently to what their master has just announced to them: ‘Truly, truly, I say to you, one of you will betray me’ (John 13:21).
Peter, leaning behind Judas, gets John’s attention and whispers in his ear, ‘Tell us who it is of whom he speaks.’
