As has been well said, Leonardo broke up the old formality and immobility of the earlier painters and brought life and action into the scene. For the first time the personages are deprived of their halos and there is nothing to make the group of men anything more than human beings deeply interested in a great purpose and disturbed to the depths of their beings by the suggestion from the Master Himself that now that purpose was to be thwarted by the treason of one of their number. This conception seems all the more natural when we recall that none of them had as yet been confirmed in grace, that one was to deny, another betray and all were to be hesitant and cowardly in a great moment of trial.
With all this of thought in Leonardo's picture it might be expected that all of his attention would be given to the faces and little to the composition itself and to the setting of the picture. The exact contrary is what happens. The composition is probably the most wonderful ever done. The room itself is so arranged that everything leads the eye toward the centre of the picture where the Master sits, while behind Him the middle one of three windows, with an arched casement, frames Him apart from the Apostles. Through these three windows at the back can be seen one of the varied mountainous landscapes that Leonardo delighted in. The extent of the landscape which can be seen shows that the supper was held in an "upper room." The bare beams of the ceiling in that coffered arrangement common in Italy, the walls ornamented with large panel spaces filled in with a damasked pattern are all worked over with artistic completeness of detail. It is details of this kind one might expect the painter of the Last Supper to have overlooked in his intentness on the sublime moment and the characters. The tablecloth, moreover, is beautifully worked and the linen and the pattern of it and the folds are done with as meticulous care as one might expect from a _genre_ painter of tissues. The glasses and table service are very carefully drawn and every detail was executed with { 20} an artistic conscience and eye to perfection, even of trifles, that reveals the thoroughness and all-embracing skill of the artist.
