After killing his own children in a fit of madness brought on by the goddess Hera, the Greek hero Heracles (in Latin Hercules) was required to atone with ten near-impossible tasks, including slaying the Lernaean Hydra and capturing the Cretan Bull.  Through a combination of ingenuity, courage and extraordinary strength, he completed all ten labours, but two were discounted.  A further two were added, which he also accomplished.
