The winged messenger of the Olympians, Hermes was the son of Zeus and Maia. As a friend to the mortals, he introduced weights and measures and he also escorts the dead to Hades. He is the giver of good luck and he taught mortals all arts, such as how to make roads and markets. In ancient times, a bust of Hermes was placed at the top of pillars to mark boundaries. His symbols were winged sandals and helmet.
