Hera and Herakles

Zeus fell in love with the mortal woman Alkmene. She had Zeus' child and he was called Herakles. Hera was so jealous of the child, she stopped him becoming a king by delaying the day of his birth so that a different woman's child became king. She also placed two snakes in the baby Herakles' cot. Herakles survived by strangling the two serpents. Even at such a young age Herakles had superhuman strength.
