TACITUS, Annales I.5
[I.v] Haec atque talia agitantibus gravescere valetudo Augusti, et quidam scelus uxoris suspectabant. quippe rumor incesserat, paucos ante menses Augustum, electis consciis et comite uno Fabio Maximo, Planasiam vectum ad visendum Agrippam; multas illic utrimque lacrimas et signa caritatis spemque ex eo fore ut iuvenis penatibus avi redderetur: quod Maximum uxori Marciae aperuisse, illam Liviae. gnarum id Caesari; neque multo post extincto Maximo, dubium an quaesita morte, auditos in funere eius Marciae gemitus semet incusantis, quod causa exitii marito fuisset. utcumque se ea res habuit, vixdum ingressus Illyricum Tiberius properis matris litteris accitur; neque satis conpertum est, spirantem adhuc Augustum apud urbem Nolam an exanimem reppererit. acribus namque custodiis domum et vias saepserat Livia, laetique interdum nuntii vulgabantur, donec provisis quae tempus monebat simul excessisse Augustum et rerum potiri Neronem fama eadem tulit.
[1.5] While these and like topics were discussed, the infirmities of Augustus increased, and some suspected guilt on his wife's part. For a rumour had gone abroad that a few months before he had sailed to Planasia on a visit to Agrippa, with the knowledge of some chosen friends, and with one companion, Fabius Maximus; that many tears were shed on both sides, with expressions of affection, and that thus there was a hope of the young man being restored to the home of his grandfather. This, it was said, Maximus had divulged to his wife Marcia, she again to Livia. All was known to Caesar, and when Maximus soon afterwards died, by a death some thought to be self-inflicted, there were heard at his funeral wailings from Marcia, in which she reproached herself for having been the cause of her husband's destruction. Whatever the fact was, Tiberius as he was just entering Illyria was summoned home by an urgent letter from his mother, and it has not been thoroughly ascertained whether at the city of Nola he found Augustus still breathing or quite lifeless. For Livia had surrounded the house and its approaches with a strict watch, and favourable bulletins were published from time to time, till, provision having been made for the demands of the crisis, one and the same report told men that Augustus was dead and that Tiberius Nero was master of the State.
