The great myths of Ancient Greece have inspired mankind for centuries. Each of the heroes has to undergo trials of strength and courage to prove his valor against a host of monsters - the Minotaur, half man, half bull; Hydra, the many-headed serpent; Medusa the Gorgon. Meanwhile, the gods, lead by Zeus the Thunderer from his seat on Mount Olympus, watch, encourage, help - and sometimes hinder.
