Ladon

Greek The dragon who guarded the garden where the apples of the Hesperides were kept. In this garden, on Mount Atlas, there was a tree that bore golden fruit. The tree was a present from Gaia to Hera on her marriage to Zeus. No mortals knew the whereabouts of this sacred tree. It was the last task of the hero Heracles to find and collect some of the apples. This Heracles did with the help of Atlas, a Titan. Heracles then killed the dragon, incurring the wrath of Hera.
