In ancient Greek religion Artemis Caryatis was an epithet of Artemis that was derived from the small polis of Caryae in Laconia; there an archaic open-air temenos was dedicated to Carya, the Lady of the Nut-Tree, whose priestesses were called the caryatidai, represented on the Athenian Acropolis as the marble caryatids supporting the porch of the Erechtheum.
