Heracles when driven mad by the goddess Hera
Murdered
his three children and his wife Megara
The
Delphic oracle punished him for the murders
By
ordering him to perform the Twelve Labors
The
labors were set by king Eurystheus his cousin
His
tenth labor was stealing the cattle of Geryon
The
three headed Geryon owned the herd of cattle
It
was he and two headed Orthrus he had to battle
After
clubbing the hound with just a single blow
Heracles
stole the cattle dispatching Geryon also
