Hera and Herakles

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