Argive Heraion

The Heraion of Argos is an ancient sanctuary in the Argolid, Greece, dedicated to Hera, whose epithet "Argive Hera" appears in Homer's works. Hera herself claims to be the protector of Argos in Iliad IV, 50–52): "The three towns I love best are Argos, Sparta and Mycenae of the broad streets". The memory was preserved at Argos of an archaic, aniconic pillar representation of the Great Goddess. The site, which might mark the introduction of the cult of Hera in mainland Greece, lies northeast of Argos between the sites of Mycenae and Midea, two important Mycenaean cities. The traveller Pausanias, visiting the site in the 2nd century CE, referred to the area as Prosymna.
