Did you know according to Greek mythology the Milky Way arose from breast milk. The divine hero Heracles was born to Zeus and Alcmene. Alcmene was a mortal human so Zeus gave Heracles to his other wife Hera to feed him with goddess milk to make him immortal. But baby Heracles bit Hera into her nipple so she let go and her milk poured down the sky and formed the Milky Way. The picture is painted by Peter Paul Ruben.
