BOOK II. ch. 16.--_Dragon in Lavinium.
There is a peculiar divination of the dragon, for in Lavinium, a town of the Latins but in Lavinium, there is a large and dense sacred grove, and near it the shrine of the Argolic Juno. Within the grove is a cave and deep den, the lair of a dragon.
Sacred virgins enter this grove on stated days, who carry a barley cake in their hands, with bandaged eyes. A certain divine afflatus leads them accurately to the den, and gently, and step by step, they proceed without hindrance, and as if their eyes were uncovered. If they are virgins, the dragon admits the food as pure and fit for a deity. If otherwise, it does not touch it, perceiving and divining them to be impure.
Ants, for the sake of cleansing the place, carry from the grove the cake left by the vitiated virgin, broken into little pieces, so that they may easily carry it. When this happens, it is perceived by the inhabitants, and those who have entered are pointed out and examined, and whoever proves to have forfeited her virginity is punished with the penalties appointed by the laws.
"The masculine sex also seems to be privileged by nature among brutes, inasmuch as the male dragon is distinguished by a crest and hairs, with a beard."
