He who passes under the litter on which they are borne, is put to death. For their minor offences the virgins are punished with stripes, the Pontifex Maximus sometimes scourging the culprit on her bare flesh, in a dark place, with a curtain interposed. But she that has broken her vow of chastity is buried alive near the Colline gate. Here a little ridge of earth extends for some distance along the inside of the city-wall; the Latin word for it is agger.
Under it a small chamber is constructed, with steps leading down from above. In this are placed a couch with its coverings, a lighted lamp, and very small portions of the necessaries of life, such as bread, a bowl of water, milk, and oil, as though they would thereby absolve themselves from the charge of destroying by hunger a life which had been consecrated to the highest services of religion.
