Herculean
adjective
ˌhər-ˈkyü-lē-
Did you know?
The hero Hercules, son of the god Zeus by a human mother, was famous for his superhuman strength. As penance for a madness-induced murder spree (the victims were his family), he was forced to perform twelve enormously difficult tasks, or “labors.” These ranged from descending into the underworld to bring back the terrifying dog that guarded its entrance to destroying the many-headed monster called the Hydra. The feats he accomplished explain how Herculean in the 16th century came to be used for any job or task that’s extremely difficult or calls for enormous strength.
