Lastly, we come to the religious, or rather superstitious, part played by Fish in the ancient times. That the Egyptians employed Fish as material symbols of Divine attributes we learn from secular writers, such as Herodotus and Strabo.
The Jews, who seem to have had an irrepressible tendency to idolatry, and to have adopted the idols of every people with whom they came in contact, resuscitated the Fish-worship of Egypt as soon as they found themselves among the Philistines. We might naturally imagine that as the Israelites were bitterly opposed to their persistent enemy, who trod them under foot and crushed every attempt at rebellion for more than three hundred years, they would repudiate the worship as well as the rule of their conquerors. But, on the contrary, they adopted the worship of Dagon, the Fish-god, who was the principal deity of the Philistines, and erected temples in his honour.
Their tendency to this Fish-worship is specially noticed in the commandment that they were not to worship "the likeness of anything that creepeth on the ground" (i.e. serpent-worship), "the likeness of any fish that is in the waters beneath the earth" (Deut. iv. 18).
We learn from 1 Sam. v. 4 the form of this idol: "When they arose early on the morrow morning, behold, Dagon was fallen upon his face to the ground before the ark of the Lord; and the head of Dagon and both the palms of his hands were cut off upon the threshold; only the stump of Dagon was left to him."
If the reader will refer to this passage, he will see that the latter part is rendered in the marginal reading as "the fishy part was left to him." The Jewish Bible has nearly the same reading, "only a fish-stump had remained of him."
It is evident, therefore, that Dagon had the head, body, and arms of a man, and that the figure terminated in a Fish's tail. In fact, there is little doubt that to the various figures of this deity is owing the wide-spread belief in mermen. We find the same image among the Assyrians, who not only represented the god as half man and half fish, but who dressed his priest in a garment representing the skin of a Fish, with the head worn as a helmet, and the rest of the skin flowing down the back.
We find precisely the same worship at the present day in Siam, where Dagon has exactly the same form as among the Philistines of old. There is now before me a photograph of a great temple at Ayutia, the entrance to which is guarded by two huge images of the Fish-god. They are about sixty feet in height, and have both legs and feet like man, but in addition the lower part of the body is modified into the tail of a Fish, which, in common with the whole of the body, is covered with gilded scales.
It is conjectured that the Fish was chosen as an emblem of fecundity, on account of the wonderful fertility of the Fish tribes. That the Israelites were familiarly acquainted with this fact is shown by a passage in the benediction of Jacob. In speaking of Joseph, he uses these words: "The Angel which redeemed me from all evil, bless the lads; and let my name be named on them, and the name of my fathers Abraham and Isaac; and let them grow into a multitude" ("as fishes do increase," marg. trans.) "in the midst of the earth" (Gen. xlviii. 16).
In order that the reader may see examples of the typical Fish which are to be found in Egypt and Palestine, I have added three more species, which are represented in the following illustration.
