Tityus.
A son of Zeus and the nymph Elara (or another), Tityus was a giant. To hide the pregnant mother from Hera's jealousy, Zeus concealed her in the depths of the earth, from which Tityus emerged (hence his frequent identification as a son of Gaia). When grown, Tityus was incited by Hera to attack Leto, another of Zeus's conquests. He was either shot by Leto's children, Apollo and Artemis, or struck down by a thunderbolt from Zeus. For his presumption, Tityus was eternally punished in Hades: his body was stretched across nine acres and snakes (or vultures) ate his heart and liver, which were renewed with the phases of the moon.
    Tityus is commonly depicted in the postclassical arts being tortured in Hades by a vulture. Because of the similar nature of the torments, such portrayals are sometimes confused with those of Prometheus bound. Tityus is often grouped with Ixion, Sisyphus, and Tantalus, known collectively as the Four Blasphemers (or Deceivers, Disgracers, Condemned).
