At the centre of Hecate's sphere of influence there stands the moon. What the moon sheds her light on is in its turn highly ambiguous: on the one hand we have motherly solicitude and the growth of all living things, on the other more indecency and deadliness—not in the sense of the bride dying in order to give life, but in the sense of witchcraft and ghosts.
Kerényi defines Hecate's essential character as lunar ambiguity—simultaneously nurturing and death-dealing—and identifies her with witchcraft, the howling dog, and the distorted aspect of Artemis.
