Revelation 12:16

The dragon is unexpectedly baffled by the earth, as the woman's ally, which swallows the persecutors like Korah, Dathan, and Abiram (Numbers 16:30-32). This enigmatic detail has not yet been paralleled from Jewish or early Christian literature, for Protev. Jacobi, 22 (cited by Selwyn, 7 9) is even more remote than 4 Esd. 13:44. Probably it was retained from the astrological setting of the original myth: Cetos, the aquatic dragon of the southern heavens, which astrologically is a watery region, casts forth the river of Êridanos, which is swallowed up in the zodiac as it flows down the heavens into the underworld.
