Hermes, the son of Zeus and Maia. As a messenger God there are many stamps of Hermes. The first Greek stamps, the “Hermes Heads”, were issued in October 1861 but they were produced in France. The engraver was Albert Barre. Hermes was the only figure for around 30 years although many versions were produced. Among other things Hermes is also a protector of the Thieves. The Greek post office has Hermes as its symbol.
A Herma is a rectangular pillar with the head of Hermes on the top and the genitals near the base. They were used as markers or boundaries and roads. In 451 BC one night many were destroyed maybe as a protest for the expedition of the Athenians against Syracuse.

Hermes with the Caduceus, a rod entwined with a pair of snakes, a symbol of healing and of peace. Asclepius' snakes tied to a stick symbol, the caduceus of medical art, has been suggested to represent a way of inoculating patients with non-lethal doses of snake venom, a primitive hypodermic injection device. Snake venom is chemically similar to bee venom and seems to be an important material in treating various kinds of arthritis. The caduceus was originally only an olive branch with the stemmata which were afterward formed into snakes (Müller, Archäologie der Kunst, p504). Hyginus provides another explanation: Mercury once found two snakes fighting, and divided them with his wand; from which circumstance they were used as an emblem of peace.
