From this family Tiberius Caesar is descended; indeed both by the father and mother's side; by the former from Tiberius Nero, and by the latter from Appius Pulcher, who were both sons of Appius Caecus. He likewise belonged to the family of the Livii, by the adoption of his mother's grandfather into it; which family although plebeian, made a distinguished figure, having had the honour of eight consulships, two censorships, three triumphs, one dictatorship, and the office of master of the horse; and was famous for eminent men, particularly, Salinator and the Drusi. Salinator, in his censorship,A.U.C. 550 branded all the tribes, for their inconstancy in having made him consul a second time, as well as censor, although they had condemned him to a heavy fine after his first consulship. Drusus procured for himself and his posterity a new surname, by killing in single combat Drausus, the enemy's chief. He is likewise said to have recovered, when pro-praetor in the province of Gaul, the gold which was formerly given to the Senones, at the siege of the capitol, and had not, as is reported, been forced from them by Camillus. His great-great-grandson, who, for his extraordinary services against the Gracchi, was styled the "Patron of the Senate," left a son, who, while plotting in a sedition of the same description, was treacherously murdered by the opposite party.A.U.C. 663

But the father of Tiberius Caesar, being quaestor to Caius Caesar, and commander of his fleet in the war of Alexandria, contributed greatly to its success. He was therefore made one of the high-priests in the room of Publius Scipio;A.U.C. 707 and was sent to settle some colonies in Gaul, and amongst the rest, those of Narbonne and Arles. These, and other towns in the south of France, became, and long continued, the chief seats of Roman civilization among the Gauls; which is marked by the magnificent remains of ancient art still to be seen. Aries, in particular, is a place of great interest. After the assassination of Caesar, however, when the rest of the senators, for fear of public disturbances, were for having the affair buried in oblivion, he proposed a resolution for rewarding those who had killed the tyrant. Having filled the office of praetor,A.U.C. 710 and at the end of the year a disturbance breaking out amongst the triumviri, he kept the badges of his office beyond the legal time; and following Lucius Antonius the consul, brother of the triumvir, to Perusia,A.U.C. 713 though the rest submitted, yet he himself continued firm to the party, and escaped first to Praeneste, and then to Naples; whence, having in vain invited the slaves to liberty, he fled over to Sicily. But resenting his not being immediately admitted into the presence of Sextus Pompey, and being also prohibited the use of the fasces, he went over into Achaia to Mark Antony; with whom, upon a reconciliation soon after brought about amongst the several contending parties, he returned to Rome; and, at the request of Augustus, gave up to him his wife Livia Drusilla, although she was then big with child, and had before borne him a son. He died not long after; leaving behind him two sons, Tiberius and Drusus Nero.

Some have imagined that Tiberius was born at Fundi, but there is only this trifling foundation for the conjecture, that his mother's grandmother was of Fundi, and that the image of Good Fortune was, by a decree of the senate, erected in a public place in that town. But according to the greatest number of writers, and those too of the best authority, he was born at Rome, in the Palatine quarter, upon the sixteenth of the calends of December [16th Nov.], when Marcus AEmilius Lepidus was second time consul, with Lucius Munatius Plancus,A.U.C. 712. Before Christ about 39. after the battle of Philippi; for so it is registered in the calendar, and the public acts. According to some, however, he was born in the preceding year, in the consulship of Hirtius and Pansa; and others say, in the year following, during the consulship of Servilius Isauricus and Antony.

His infancy and childhood were spent in the midst of danger and trouble; for he accompanied his parents everywhere in their flight, and twice at Naples nearly betrayed them by his crying, when they were privately hastening to a ship, as the enemy rushed into the town; once, when he was snatched from his nurse's breast, and again, from his mother's bosom, by some of the company, who on the sudden emergency wished to relieve the women of their burden. Being carried through Sicily and Achaia, and entrusted for some time to the care of the Lacedaemonians, who were under the protection of the Claudian family, upon his departure thence when travelling by night, he ran the hazard of his life, by a fire which, suddenly bursting out of a wood on all sides, surrounded the whole party so closely, that part of Livia's dress and hair was burnt. The presents which were made him by Pompeia, sister to Sextus Pompey, in Sicily, namely, a cloak, with a clasp, and bullae of gold, are still in existence, and shewn at Baiae to this day. After his return to the city, being adopted by Marcus Gallius, a senator, in his will, he took possession of the estate; but soon afterwards declined the use of his name, because Gallius had been of the party opposed to Augustus. When only nine years of age, he pronounced a funeral oration in praise of his father upon the rostra; and afterwards, when he had nearly attained the age of manhood, he attended the chariot of Augustus, in his triumph for the victory at Actium, riding on the left-hand horse, whilst Marcellus, Octavia's son, rode that on the right. He likewise presided at the games celebrated on account of that victory; and in the Trojan games intermixed with the Circensian, he commanded a troop of the biggest boys.

After assuming the manly habit, he spent his youth, and the rest of his life until he succeeded to the government, in the following manner: he gave the people an entertainment of gladiators, in memory of his father, and another for his grandfather Drusus, at different times and in different places: the first in the forum, the second in the amphitheatre; some gladiators who had been honourably discharged, being induced to engage again, by a reward of a hundred thousand sesterces. He likewise exhibited public sports, at which he was not present himself. All these he performed with great magnificence, at the expense of his mother and father-in-law. He married Agrippina, the daughter of Marcus Agrippa, and granddaughter of Caecilius Atticus, a Roman knight, the same person to whom Cicero has addressed so many epistles. After having by her his son Drusus, he was obliged to part with her,A.U.C. 744 though she retained his affection, and was again pregnant, to make way for marrying Augustus's daughter Julia. But this he did with extreme reluctance; for, besides having the warmest attachment to Agrippina, he was disgusted with the conduct of Julia, who had made indecent advances to him during the lifetime of her former husband; and that she was a woman of loose character, was the general opinion. At divorcing Agrippina he felt the deepest regret; and upon meeting her afterwards, he looked after her with eyes so passionately expressive of affection, that care was taken she should never again come in his sight. At first, however, he lived quietly and happily with Julia; but a rupture soon ensued, which became so violent, that after the loss of their son, the pledge of their union, who was born at Aquileia and died in infancy,A.U.C. 735 he never would sleep with her more. He lost his brother Drusus in Germany, and brought his body to Rome, travelling all the way on foot before it.
