24 But, my opponent says, these are not the rites of our state. Who, pray, says this, or who repeats it? is he Roman, Gaul, Spaniard, African, German, or Sicilian? And what does it avail your cause if these stories are not yours, while those who compose them are on your side? Or of what importance is it whether you approve of them or not, since what you yourselves say are found to be either just as foul, or of even greater baseness? For do you wish that we should consider the mysteries and those ceremonies which are named by the Greeks Thesmophoria, in which those holy vigils and solemn watchings were consecrated to the goddess by the Athenians?
Do you wish us, I say, to see what beginnings they have, what causes, that we may prove that Athens itself also, distinguished in the arts and pursuits of civilization, says things as insulting to the gods as others, and that stories are there publicly related under the mask of religion just as disgraceful as are thrown in our way by the rest of you? Once, they say, when Proserpine, not yet a woman and still a maiden, was gathering purple flowers in the meadows of Sicily, and when her eagerness to gather them was leading her here and there in all directions, the king of the shades, springing forth through an opening of unknown depth, seizes and bears away with him the maiden, and conceals himself again in the bowels of the earth.
Now when Ceres did not know what had happened, and had no idea where in the world her daughter was, she set herself to seek the lost one all over the world. She snatches up two torches lit at the fires of Aetna; and giving herself light by means of these, goes on her quest in all parts of the earth.
