It is well known that the oldest representations of the Redeemer are purely ideal. He appears as a young man, with no beard, his hair arranged in the Roman style, wearing a short tunic, and showing the amiable countenance of the Good Shepherd. I give here a characteristic specimen of this type, a statue of the first quarter of the third century, now in the Lateran Museum.[166] Whether performing one of the miracles which prove his divinity, or teaching the new doctrine to the disciples, the type never varies. It is evident that the Christian painters or sculptors of the first three centuries, in drawing or modelling the head of Jesus, had no intention of making a likeness, but only a conventional type, noble and classic, and suggestive of the eternal youth of the Word. A new tendency appears in Christian art towards the middle of the fourth century, the attempt to reproduce the genuine portrait of Christ, or what was regarded as such by the Orientals. The change was a consequence of the peace and freedom given to the Church, and of the cessation of that overbearing contempt in which the Gentiles had held a religion which they believed to be that of the vile followers of a crucified Jew. It had been considered prudent, at the outset, to present the Redeemer to the neophytes, who were not yet entirely free from pagan ideas, in a type which was familiar and pleasing to the Roman eye, rather than with the characteristics of a despised race. The triumph of the Church made these precautions unnecessary, and then arose the desire of exhibiting a truer portraiture of Christ. The first addition to the conventional type was that of the beard, and probably of the hair parted in the middle.
