Aegina was one of Zeus' many lovers. Suprisingly, Zeus was able to hide Aegina from the watchful eyes of his wife. Zeus slept with Aegina and she bore him a son named Aeacus. He grew up to a king. However, Hera soon dicovered about Aeacus. As usual Hera was very upset and angry when she knew about this. As an act of vengeance, Hera sent two snakes to poison the entire island's water which ultimately led the death of it's population.
