SUETONIUS, Life of Tiberius
[L] Odium aduersus necessitudines in Druso primum fratre detexit, prodita eius epistula, qua secum de cogendo ad restituendam libertatem Augusto agebat, deinde et in reliquis. Iuliae uxori tantum afuit ut relegatae, quod minimum est, offici aut humanitatis aliquid impertiret, ut ex constitutione patris uno oppido clausam domo quoque egredi et commercio hominum frui uetuerit; sed et peculio concesso a patre praebitisque annuis fraudauit, per speciem publici iuris, quod nihil de his Augustus testamento cauisset. Matrem Liuiam grauatus uelut partes sibi aequas potentiae uindicantem, et congressum eius assiduum uitauit etlongiores secretioresque sermones, ne consiliis, quibus tamen interdum et egere et uti solebat, regi uideretur. Tulit etiam perindigne actum in senatu, ut titulis suis quasi Augusti, ita et "Liuiae filius" adiceretur. Quare non "parentem patriae" appellari, non ullum insignem honorem recipere publice passus est; sed et frequenter admonuit, maioribus nec feminae conuenientibus negotiis abstineret, praecipue ut animaduertit incendio iuxta aedem Vestae et ipsam interuenisse populumque et milites, quo enixius opem ferrent, adhortatam, sicut sub marito solita esset.
50. He first manifested hatred towards his own relations in the case of his brother Drusus, betraying him by the production of a letter to himself, in which Drusus proposed that Augustus should be forced to restore the public liberty. In course of time, he showed the same disposition with regard to the rest of his family. So far was he from performing any office of kindness or humanity to his wife, when she was banished, and, by her father's order, confined to one town, that he forbad her to stir out of the house, or converse with any men. He even wronged her of the dowry given her by her father, and of her yearly allowance, by a quibble of law, because Augustus had made no provision for them on her behalf in his will. Being harassed by his mother, Livia, who claimed an equal share in the government with him, he frequently avoided seeing her, and all long and private conferences with her, lest it should be thought that he was governed by her counsel, which, notwithstanding, he sometimes sought, and was in the habit of adopting. He was much offended at the senate, when they proposed to add to his other titles that of the Son of Livia, as well as Augustus. He, therefore, would not allow her to be called " the Mother of her Country," nor to receive any extraordinary public distinction. Nay, he frequently admonished her "not to meddle with weighty affairs, and such as did not suit her sex;" especially when he found her present at a fire which broke out near the Temple of Vesta,' and encouraging the people and soldiers to use their utmost exertions, as she had been used to do in the time of her husband.
