Annius Of Viterbo, an Italian Dominican, born at Viterbo about 1432, died Nov. 13, 1502. His real name was Giovanni Nanni, which he Latinized into Johannes Annius. He enjoyed the especial favor of Pope Alexander VI. and his family; though his death was believed to have been caused by poison administered by command of Caesar Borgia, who wished to be rid of one whose plainness of speech offended his pride. Annius published in 1498 Anti-quitatum Volumina XVII., purporting to be a collection of works of ancient authors previously supposed to be lost, including Berosus, Marcus Cato, Manetho, and others. It has long since been condemned as spurious.
