11 Let the Vestal Virgins, he says, retain their privileges. Let those speak thus, who are unable to believe that virginity can exist without reward, let those who do not trust virtue, encourage by gain. But how many virgins have the promised rewards gained for them? Hardly are seven Vestal Virgins received. See the whole number whom the fillets and chaplets for the head, the dye of the purple robes, the pomp of the litter surrounded by a company of attendants, the greatest privileges, immense profits, and a prescribed time of virginity have gathered together.
