Gustave Moreau French, 1826-1898 - Hercules and the Lernaean Hydra (Λερναῖα Ὕδρα https://en.wikipedia.org/wiki/Lernaean_Hydra ) --- After the many-headed monster Hydra in Greek mythology. When its one head was cut off, it sprouted two more. It was ultimately slain by Hercules. From Latin Hydra, from Greek Hudra (water snake). Ultimately from the Indo-European root wed- (water, wet), which also gave us water, wash, winter, hydrant, redundant, otter, and vodka.
