The Hydra is a water beast, a many headed serpent, from Greek mythology. Be very careful. Don’t get in a fight with Hydra, for every time you cut off a head, two grow back!
The Centaur is a mythical creature composed of horse and man. The idea may first have come from seeing a man riding a horse. Centaurs are wild, untamed creatures.
The fabled Unicorn is a horned animal symbolizing purity and grace. Only a pure virgin could catch a Unicorn. You’d think there would be more Unicorns around today.
Sirens originated in Greek mythology, dangerous femme fatales luring sailors to their deaths through song. Helen called them “winged maidens, daughters of the earth.” Pass the bee’s wax.
