1286 BCE — Zeus seduces Alcmene

Alcmene was the grand-daughter of Perseus, one of the earliest Greek heroes, and himself a son of Zeus. Perhaps this is why Zeus, in seducing his great grand-daughter, chose to do do by assuming the form of her husband, although it’s likely that Alcmene’s famed fidelity had something to do with that.

Be that as it may, Zeus (in the form of Amphitryon, Alcmene’s husband) lay with her for three nights (in contrast to his usual “wham-bam-thank-me-ma’am” style), and the product of their union was the mighty Herakles (or Hercules, to use the better known Latin spelling), greatest and most-famed of all the heroes of Greece.
