This goddess was angry when her nymph Callisto was seduced by Zeus, and directly after her birth, she assisted her mother in birthing her brother.  Another story concerning this goddess revolves around her punishing Actaeon for spying on her while bathing by turning him into a stag, after which he was killed by hounds.
