Drawing of lots was frequently resorted to by the Romans wishing to pry into futurity. The lots were dice, or articles resembling those instruments of chance. They were thrown into an urn filled with water, or cast as dice in the ordinary way. If there was any difficulty in ascertaining the import of the dice throwing, the priests were employed to interpret. Future events were frequently inquired into by an inquisitive person cutting the branch of a tree into small pieces, and distinguishing them by certain marks, and then scattering them at random on a white cloth. The searcher after knowledge having prayed to the gods, took up the slips three times, and interpreted according to the marks. Future events were often inquired into by reading the first line or passage which happened to turn up on opening a book, or by observing the stars. It was supposed to be lucky to be born under a certain star, and unlucky to come into the world under another. Astrologers were consulted regarding one's natal hour. Fortune-tellers and books of fate were consulted on the most trivial occasions; and persons aspiring to the magistracy, after saying their prayers in the open air, had recourse to augury with the view of ascertaining whether the gods favoured their cause. Great attention was paid by the Romans to dreams, and persons of disordered minds were supposed to possess the faculty of presaging future events. Omens of futurity were also drawn from the appearance of the entrails of animals offered in sacrifice to the gods. The flame and smoke from the altar were noticed, and so were the circumstances attending the driving, felling, and bleeding of the victim. Sibylline books were inspected by appointment of the senate at perilous times, as they were supposed to contain the fate of the Roman Empire. There was something mysterious about the origin of the sibylline books. It is reported that a woman called Amalthæa, from a foreign country, came to Tarquin the Proud to sell nine sibylline books. Upon Tarquin refusing to give her the price asked, she went away and burned three of them. Returning soon after, she sought the same price for the remaining six. Still the price was refused, and she went away and burned other three books. She again came to the king, and demanded the same price for the three unconsumed volumes as she had asked for the nine. Tarquin, who first regarded the woman as a senseless old creature, became surprised at her strange behaviour, and inquired at the augurs what he should do. They advised him to give the woman the price she demanded. The woman delivered the books, and, after desiring that they should be carefully kept, disappeared, and was never seen again.
