Another symbol of the Saviour which is frequently found in the works of the first three centuries, and which soon afterwards seems to have fallen almost entirely into disuse, is that of the Fish. It is not derived, like that of the Good Shepherd, immediately from the words of Scripture; though its use undoubtedly recalled several familiar narratives. It seems to have been early associated with the well-known Greek formula, [Greek: iaesous christos theon uios sotaer], Jesus Christ the Saviour Son of God, arranged acrostically, so that the first letters of its words formed the word [Greek: ichthus], fish. The first association that its use would suggest was that of Christ's call to Peter and Andrew, "Follow me, and I will make you fishers of men,"--and thus we find, among the early Christian writers, the name of "little fish," _pisciculi_, applied to the Christian disciples of their times. But it would serve also to bring to memory the miracle that the multitude had witnessed, of the multiplication of the fishes; and it would recall that last solemn and tender farewell meeting between the Apostles and their Lord on the shore of the Sea of Tiberias, in the early morning, when their nets were filled with fish,--and "Jesus then cometh, and taketh bread, and giveth them, and fish likewise." And with this association was connected, as we learn from the pictures in the catacombs, a still deeper symbolic meaning, in which it represented the body of our Lord as given to his apostles at the Last Supper. In the Cemetery of Callixtus, very near the recently discovered crypt of Pope Cornelius, are two square sepulchral chambers, adorned with pictures of an early date. Those of the first chamber have almost utterly perished, but on the wall of the second may be seen the image of a fish swimming in the water, and bearing on his back a basket filled with loaves of the peculiar shape and color used by the Jews as an offering of the first fruits to their priests; beneath the bread appears a vessel which shows a red color, like a cup filled with wine. "As soon as I saw this picture," says the Cavaliere de Rossi, in his account of the discovery, "the words of St. Jerome came to my mind,-- 'None is richer than he who bears the body of the Lord in an osier basket and his blood in a glass.'"
