Note 605 — INDEX TO THE NOTES.

Harpies and Hydras. The Harpies (lit. ‘spoilers’) were unclean monsters, being birds with the heads of maidens, with long claws and gaunt faces. Hydras, here used as a general name for monstrous water-serpents (Gk. hydōr, water); the name was first given to the nine-headed monster slain by Hercules. See Son. xv. 7, “new rebellions raise Their Hydra heads”; the epithet ‘hydra-headed’ being applied to a rebellion, an epidemic, or other evil that seems to gain strength from every endeavour to repress it.
