And the same, in the tenth book of the _Republic_, mentions Eros the son of Armenius, who is Zoroaster. Zoroaster, then, writes: “These were composed by Zoroaster, the son of Armenius, a Pamphyllian by birth: having died in battle, and been in Hades, I learned them of the gods.” This Zoroaster, Plato says, having been placed on the funeral pyre, rose again to life in twelve days. He alludes perchance to the resurrection, or perchance to the fact that the path for souls to ascension lies through the twelve signs of the zodiac; and he himself says, that the descending pathway to birth is the same. In the same way we are to understand the twelve labours of Hercules, after which the soul obtains release from this entire world. I do not pass over Empedocles, who speaks thus physically of the renewal of all things, as consisting in a transmutation into the essence of fire, which is to take place. And most plainly of the same opinion is Heraclitus of Ephesus, who considered that there was a world everlasting, and recognised one perishable--that is, in its arrangement, not being different from the former, viewed in a certain aspect. But that he knew the imperishable world which consists of the universal essence to be everlastingly of a certain nature, he makes clear by speaking thus: “The same world of all things, neither any of the gods, nor any one of men, made. But there was, and is, and will be ever-living fire, kindled according to measure,[852] and quenched according to measure.” And that he taught it to be generated and perishable, is shown by what follows: “There are transmutations of fire,--first, the sea; and of the sea the half is land, the half fiery vapour.” For he says that these are the effects of power. For fire is by the Word of God, which governs all things, changed by the air into moisture, which is, as it were, the germ of cosmical change; and this he calls sea. And out of it again is produced earth, and sky, and all that they contain. How, again, they are restored and ignited, he shows clearly in these words: “The sea is diffused and measured according to the same rule which subsisted before it became earth.” Similarly also respecting the other elements, the same is to be understood. The most renowned of the Stoics teach similar doctrines with him, in treating of the conflagration and the government of the world, and both the world and man properly so called, and of the continuance of our souls.
