Discerning all these things, the ancients had divination in very great use and counted it no parergy, but
would found no cities, invest themselves with no
ramparts, slay no men, wed no women, untill they
had been advised in all particulars by diviners. And
certainly their oracles were not aloof from astrology,
but at Delphi a virgin hath the office of prophet
in token of the celestial Virgin, and a serpent
giveth voice beneath the tripod because a Serpent
giveth light among the stars, and at Didymi also
the oracle of Apollo hath its name, methinks, from
the heavenly Twins. Modern philology soberly rejects the happy thought that Didyma (Dids i) owes its name to the constellation Didymi (Gemini), and explains that the name is Carian, like Idyma, Sidyma, Loryma, etc. (Birchner, in Pauly-Wissowa, 3.v.).
