ille multum de clementia principis praefatus aqua atque igni Silano interdicendum censuit ipsumque in insulam Gyarum relegandum. eadem ceteri, nisi quod Cn. Lentulus separanda Silani materna bona, quippe Atia parente geniti, reddendaque filio dixit, adnuente Tiberio. [...] atque ille prudens moderandi, si propria ira non impelleretur, addidit insulam Gyarum immitem et sine cultu hominum esse: darent Iuniae familiae et viro quondam ordinis eiusdem ut Cythnum potius concederet.
Translation :
After a long preliminary eulogy on the prince's clemency, Piso pronounced that Silanus ought to be outlawed and banished to the island of Gyarus. The rest concurred, with the exception of Cneius Lentulus, who, with the assent of Tiberius, proposed that the property of Silanus's mother, as she was very different from him, should be exempted from confiscation, and given to the son. [...] Knowing, as he did, how to be forbearing, when he was not under the stimulus of personal resentment, he further said that Gyarus was a dreary and uninhabited island, and that, as a concession to the Junian family and to a man of the same order as themselves, they might let him retire by preference to Cythnus.
