Isis went to look for them in a boat made of papyrus, and buried each part in a separate place. After this the soul of Osiris returned out of Hades to train up his son. Then came a battle between Horus and Typhon, in which Typhon was vanquished, but Isis allowed him to escape. There are other less important incidents in the story, among them that Isis had another son by the soul of Osiris after his death, who is the god called Harpocrates, represented as lame and with his finger on his mouth.[192] Plutarch declares that this story is symbolical, and mentions various explanations of the allegory. He rejects, at once, the rationalistic explanation, which turns these gods into eminent men,--sea-captains, etc. "I fear," says he, "this would be to stir things that are not to be stirred, and to declare war (as Simonides says), not only against length of time, but also against many nations and families of mankind, whom a religious reverence towards these gods holds fast bound like men astonished and amazed, and would be no other than going about to remove so great and venerable names from heaven to earth, and thereby shaking and dissolving that worship and persuasion that hath entered almost all men's constitutions from their very birth, and opening vast doors to the atheists' faction, who convert all divine matters into human." "Others," he says, "consider these beings as demons intermediate between gods and men. And Osiris afterwards became Serapis, the Pluto of the under-world." Other explanations of the myth are given by Plutarch. First, the geographical explanation. According to this, Osiris is Water, especially the Nile. Isis is Earth, especially the land of Egypt adjoining the Nile, and overflowed by it. Horus, their son, is the Air, especially the moist, mild air of Egypt. Typhon is Fire, especially the summer heat which dries up the Nile and parches the land. His seventy-two associates are the seventy-two days of greatest heat, according to the Egyptian opinion. Nepthys, his wife, sister of Isis, is the Desert outside of Egypt, but which in a higher inundation of the Nile being sometimes overflowed, becomes productive, and has a child by Osiris, named Anubis. When Typhon shuts Osiris into the ark, it is the summer heat drying up the Nile and confining it to its channel. This ark, entangled in a tree, is where the Nile divides into many mouths at the Delta and is overhung by the wood. Isis, nursing the child of the king, the fragrance, etc., represent the earth nourishing plants and animals. The body of Osiris, torn by Typhon into fourteen parts, signifies either the division of the Nile at its mouths or the pools of water left after the drying up of the inundation.
