the name of the Cumean Sibyl, who offered to Tarquinius Superbus nine books, containing the Roman deities, and demanded 300 pieces of gold for them. He derided her; whereupon she threw three of them into the fire; and returning, asked the same price for the other six; which being denied, she burnt three more; and returned, still demanding the same price. Upon which Tarquin consulting the pontiffs, was advised to buy them. These books were in such esteem, that two magistrates were created to consult them upon extraordinary occasions.
