DIO CASSIUS,
Roman History LV.1-2
LV.1
The events related happened in the consulship of Iullus Antonius and Fabius Maximus. In the following year Drusus became consul with Titus Crispinus, and omens occurred that were anything but favorable to him. Many buildings were destroyed by storm and by thunderbolts, among them many temples; even that of Jupiter Capitolinus and the gods worshipped with him was injured. Drusus, however, paid no heed to any of these things, but invaded the country of the Chatti and advanced as far as that of Suebi, conquering with difficulty the territory traversed and defeating the forces that attacked him only after considerable bloodshed. From there he proceeded to the country of the Cherusci, and crossing the Visurgis, advanced as far as the Albis, pillaging everything on his way. The Albis rises in the Vandalic Mountains, and empties, a mighty river, into the northern ocean. Drusus undertook to cross this river, but failing in the attempt, set up trophies and withdrew. For a woman of superhuman size met him and said: “Whither, pray, art thou hastening, insatiable Drusus? It is not fated that thou shalt look upon all these lands. But depart; for the end alike of thy labors and of thy life is already at hand.” It is indeed marvelous that such a voice should have come to any man from the Deity, yet I cannot discredit the tale; for Drusus Immediately departed, and was returning in haste, died on the way of some disease before reaching the Rhine. And I find confirmation of the story in these incidents: wolves were prowling about the camp and howling just before his death; two youths were seen riding through the midst of the camp; a sound as of women lamenting was heard; and there were shooting stars in the sky. So much for these events

LV.2
Augustus, upon learning of Drusus’ illness before it was far advanced (for he was not far off), had sent Tiberius to him in haste. Tiberius found him still breathing, and on his death carried the body to Rome, causing the centurions and military tribunes to carry it over the first stage of the journey,- as far as the winter quarters of the army,- and after that the foremost men of each city. When the body had been laid in state in the Forum, two funeral orations were delivered: Tiberius pronounced one in the Circus Flaminius. The emperor, of course, had been away on a campaign, and it was not lawful for him to omit the customary rites in honor of his exploits at the time of his entrance inside the pomerium. The body was borne to the Campus Martius by the knights, both those who belonged strictly to the equestrian order and those who were of senatorial family; then it was given to the flames and the ashes were deposited in the sepulcher of Augustus. Drusus, together with his sons, received the title of Germanicus, and he was given the further honors of statues, an arch, and a cenotaph on the bank of the Rhine itself.
Tiberius, while Drusus was yet alive, had overcome the Dalmatians and Pannonians, who had once more begun a rebellion, and he had celebrated the equestrian triumph, and had feasted the people, some on the Capitol and the rest in many other places. At the same time Livia, also, with Julia, had given a dinner to the women. And the same festivities were being prepared for Drusus; even the Feriae were to be held a second time on his account, so that he might celebrate his triumph on that occasion. But his untimely death upset these plans. To Livia statues were voted by way of consoling her and she was enrolled among the mothers of three children. For in certain cases, formerly by act of senate, but now by the emperor’s law bestows the privileges which belong to the parents of three children upon men or women to whom Heaven has not granted that number of children. In this way they are not subject to the penalties imposed for childlessness and may receive all but a few of the rewards offered for large families; and not only men but gods also may enjoy these rewards, the object being that, if any one leaves them a bequest at his death, they may receive it.
