It is a fault, as I have already observed, to represent John as asleep on the breast or the shoulder of our Saviour.
Though countenanced by the highest authorities in Art, I believe it must be considered as a fault, or at least a mistake, to represent our Saviour and his apostles as seated, instead of reclining round the table. It is a fault, not merely because the use of the triclinium or couch at all social meals was general in the antique times,—for the custom of sitting upright was not so entirely extinct among the Jews but that it might on any other occasion have been admissible,—but, from peculiar circumstances, it became in this instance an impropriety. We know that when the Passover was first instituted the Jews were enjoined to eat it standing, as men in haste, with girded loins and sandalled feet: but afterwards it was made imperative that they should eat it in an attitude of repose, lying upon couches, and as men at ease; and the reason for this was, that all the circumstances of the meal, and particularly the attitude in which it was eaten, should indicate the condition of security and freedom which the Israelites enjoyed after their deliverance from the Egyptian bondage. In the then imperfect state of Biblical criticism, this fact seems to have been unknown to the earlier artists, or disregarded by those who employed and directed them. Among modern artists, Poussin and Le Sueur have scrupulously attended to it, even when the moment chosen is the mystical distribution of the bread and wine which succeeded the Paschal Supper. Commentators have remarked, that if Christ and his disciples reclined at table, then, supposing Christ to have the central place of honour, the head of John would have been near to the bosom of Christ: but under these circumstances, if Judas were sufficiently near to receive the sop from the hand of Christ, then he must have reclined next to him on the other side, and have taken precedence of Peter. This supposed a propinquity which the early Christian artists deemed offensive and inadmissible.
In the composition by Stradano the arrangement of the table and figures is particularly well managed: all recline on couches; in the centre of the table is a dish, to which Christ extends his hand, and Judas, who is here rather handsome than otherwise, at the same time stretches forth his; the moment is evidently, ‘He that dippeth with me in the dish, the same shall betray me.’ Two circumstances spoil this picture, and bring it down to the level of the vulgar and the commonplace. In the background is seen a kitchen and the cooking of the supper. Under Judas crouches a hideous demon, with horns, hoof, and tail, visible only to the spectator.
When the Cenacolo represents the Eucharist, it is, perhaps, allowable to introduce angels, because it was, and I believe is, an established belief, that, visible or invisible, they are always present at the Sacrament. The Holy Ghost descending from above is unsanctioned by Scripture, but may serve to mark the mystical and peculiar solemnity of the moment chosen for representation. It may signify, ‘He that receiveth me, receiveth Him that sent me.’ But where angels attend, or where the Spiritual Comforter comes floating down from above, then the presence of Judas, or of any superfluous figures as spectators or servitors, or of dogs or other animals, becomes a manifest impropriety.
The introduction of the Devil in person as tempting Judas is rendered pardonable by the naïveté of the early painters: in the later schools of art it is offensive and ridiculous.
The Cenacolo of Baroccio, painted by order of Clement VIII. (1594), for his family chapel in the Santa Maria-sopra-Minerva, is remarkable for an anecdote relating to it. Baroccio, who was not eminent for a correct taste, had in his first sketch reverted to the ancient fashion of placing Satan close behind Judas, whispering in his ear, and tempting him to betray his Master. The Pope expressed his dissatisfaction,—‘che non gli piaceva il demonio si dimesticasse tanto con Gesù Cristo,’—and ordered him to remove the offensive figure. This is not the last example of the ancient manner of treatment. In the Cenacolo of Franceschini, painted nearly a century later, two angels are attending on the sacred repast, while Judas is in the act of leaving the room, conducted by Satan in person.
