Hekate was referred to on more than one occasion in connection with serpents and oak leaves. Sophocles described her in The Root-Cutters “she who is crowned with oak-leaves And the coils of wild serpents.” There is also an oak tree in the center of her garden in the Orphic Argonautica, on which hung the Golden Fleece 87.
