Four old women, left behind inside, are they who dispatch the cow. Whichever gets the chance cuts the throat of the cow with a sickle. Afterwards the doors are opened, and those who are appointed drive up a second cow, and a third after that, and yet a fourth. All are dispatched in the same way by the old women, and the sacrifice has yet another strange feature. On whichever of her sides the first cow falls, all the others must fall on the same.
Such is the manner in which the sacrifice is performed by the Hermionians. Before the temple stand a few statues of the women who have served Demeter as her priestess, and on passing inside you see seats on which the old women wait for the cows to be driven in one by one, and images, of no great age, of Athena and Demeter. But the thing itself that they worship more than all else, I never saw, nor yet has any other man, whether stranger or Hermionian. The old women may keep their knowledge of its nature to themselves.
