Tacitus (Annals 1, 14-15 A.D., Paragraph 4)  "Tiberius indeed had arrived at fulness of years, and was a distinguished captain, but possessed the inveterate pride entailed upon the Claudian race; and many indications of a cruel nature escaped him, in spite of all his arts to disguise it; besides that from his early infancy he was trained up in a reigning house, and even in his youth inured to an accumulation of power and honours, consulships and triumphs: nor during the several years of his abode at Rhodes, where, under the plausible name of retirement, a real banishment was covered, did he exercise other occupation than that of meditating future vengeance, studying the arts of treachery, and practising secret, abominable sensualities: add to these considerations, that of his mother, a woman inspired with all the tyranny of her sex; yes, the Romans must be under bondage to a woman, and moreover enthralled by two youths, who would first combine to oppress the State, and then falling into dissension, rend it piecemeal."

Josephus (Wars of the Jews, Book 2, 8.2) "They do not absolutely deny the fitness of marriage, and the succession of mankind thereby continued; but they guard against the lascivious behavior of women, and are persuaded that none of them preserve their fidelity to one man."
