There were several versions of the life and adventures of Hercules. However, it remained constant in various storytellers that the father of Hercules was Zeus, who was also the supreme god. Although he was mighty and powerful he was also a famous womanizer, and one of the mortal women he impregnated was Alceme, the wife of Amphytrion.
When Hera, Zeus’ wife, learned about this, she became enraged and was determined to harm the unborn child. Nevertheless, Alcmene was able to protect the child and gave birth to a boy, but she was so afraid of Hera's wrath that she abandoned the baby in the woods. The goddess Athena came to the rescue of the infant.
Athena decided to play a trick on Hera and took the baby to the queen of the gods to be breastfed. Hera, not knowing who the baby was, agreed, and ironically, little Hercules, whom Hera hated, was made extra strong by her divine breast milk. But the baby either sucked too hard or bit Hera’s nipple (depending on who you talk to). As the furious Hera yanked her breast away, her milk sprayed into the sky and created the Milky Way. Ironically, the baby whom Hera hated, was made extra strong by her super-charged breast milk.
Hera decided to send snakes into the child’s crib to kill him. However, the baby was amazingly strong that he was able to strangle and kill the snakes before they could hurt him.
It's at this point, that Hercules actually earned the name we know him by. (Alcmene and her husbnd Amphytrion first named the baby Alcaeus.) Since part of the reason he was so strong was because of Hera's super-powered breast milk, everybody around started calling him Hercules, which basically means glory by the aid of Hera. Which must have been the final affront to the already profoundly insulted queen of the gods.
In the second picture, Hercules is fighting Centaur Nessos, who eventually killed Hercules with a poisoned tunic.
Once, the centaur Nessus abducted her wife Deinaria and Hercules shot him with a poisoned arrow. Nessus gave Deinaria a vial of his blood, stating it was a love potion, but the two didn’t know it was now poisoned with the snake venom from Hercules’ arrow.
