If you have time, after looking at the scenes I have suggested, notice 2 other
images in the LAST DAYS OF CHRIST cycle on the lowest tier of the Arena
chapel walls (1303-06).
Firstly on the left wall as you face the Last Judgment:
1st image: KISS OF JUDAS
Judas purses his lips to kiss Christ to identify him to the soldiers who were worried about grabbing the wrong man because one of the apostles, James the Minor, resembled Christ. (Probably Italians to this day kiss on both cheeks so that they will not be associated with Judas' single kiss.) The intensity of the expressions of Christ and Judas just adds to the powerful surge of the crowds painted into the scenes. Judas can't quite look at him, as he knows how horrible it is to be a rat; he looks slightly up so as not to face his truth.
2nd image: LAMENTATION (on right wall as you face the Last Judgment)
The Lamentation, sometimes also called The Deposition, is the scene of Christ's body being taken down from the cross after his death.
Mary is convulsed with pain and sorrow as she reaches to touch her child's body and see him one more time, even if his lifeless eyes cannot return her gaze. Giotto makes the corners of her mouth tremble and he stretches the eyebrow lines and eyelines to extend her abject wretchedness.
The artist allows the viewer into the scene by painting two mourning figures seated on the ground with their backs to us; when we then take on their viewpoint, we enter the scene as mourners, too.
Even the angels are wracked with sadness and pain. Giotto is a master of the art of painting feelings and this scene is where he best expresses the nadir of human grief.
