550. Verse 9. And that great dragon was cast out, that old serpent, called the Devil, and Satan, signifies that they who are meant by "the dragon" turned from the Lord to themselves, and from heaven to the world, and thence became sensual from the corporeal, who could not but be in the evils of their lusts and thence in falsities, and by separation from the Lord and heaven became devils and satans. Who are meant by "the dragon," may be seen (n. 537); these, inasmuch as they make God three, and the Lord two, and because they place the commandments of the Decalogue among works by which there is not any salvation, are called "the old serpent, the Devil, and Satan;" and by "a serpent" is signified a man sensual from the corporeal (n. 424), who turns from the Lord to himself, and from heaven to the world; and by "the Devil" are signified they who are in the evils of lusts; and by "Satan," they who are thence in falsities (n. 97, 153 at the end, 856, 857). Such, also, was the serpent which seduced Eve and Adam, as appears from his description and the curse pronounced upon him (Gen. 3:1-5, 14-15). "The dragon" is here called "the Devil and Satan," but he is so called, because all in hell are devils and satans; and thence hell in the aggregate is so called.
