He rebuilt many noble edifices which had been destroyed by fire, and amongst them the Capitol, which had been burnt down a second time; The Capitol had been burnt, for the third time, in the great fire mentioned TITUS, c. viii. The first fire happened in the Marian war, after which it was rebuilt by Pompey, the second in the reign of Vitellius. but all the inscriptions were in his own name, without the least mention of the original founders. He likewise erected a new temple in the Capitol to Jupiter Custos, and a forum,This forum, commenced by Domitian and completed by Nerva, adjoined the Roman forum and that of Augustus, mentioned in c. xxix. of his life. From its communicating with the two others, it was called Transitorium. Part of the wall which bounded it still remains, of a great height, and 144 paces long. It is composed of square masses of freestone, very large, and without any cement; and it is not carried in a straight line, but makes three or four angles, as if some buildings had interfered with its direction. which is now called Nerva's, as also the temple of the Flavian family,The residence of the Flavian family was converted into a temple. See c. i. of the present book. a stadium, The Stadium was in the shape of a circus, and used for races both of men and hotses. an odeum, The Odeum was a building intended for musical performances. There were four of them at Rome. and a naumachia;See before, c. iv. out of the stone dug from which, the sides of the Circus Maximus, which had been burnt down, were rebuilt.

He undertook several expeditions, some from choice, and some from necessity. That against the CattiSee VESPASIAN, c. xiv. was unprovoked, but that against the Sarmatians was necessary; an entire legion, with its commander, having been cut off by them. He sent two expeditions against the Dacians; the first upon the defeat of Oppius Sabinus. a man of consular rank; and the other, upon that of Cornelius Fuscus, prefect of the pretorian cohorts, to whom he had entrusted the conduct of that war. After several battles with the Catti and Daci, he celebrated a double triumph. But for his successes against the Sarmatians, he only bore in procession the laurel crown to Jupiter Capitolinus. The civil war, begun by Lucius Antonius, governor of Upper Germany, he quelled, without being obliged to be personally present at it, with remarkable good fortune. For, at the very moment of joining battle, the Rhine suddenly thawing. the troops of the barbarians which were ready to join L. Antonius, were prevented from crossing the river. Of this victory he had notice by some presages, before the messengers who brought the news of it arrived. For upon the very day the battle was fought, a splendid eagle spread his wings round his statue at Rome, making most joyful cries. And shortly after, a rumour became common, that Antonius was slain; nay, many positively affirmed, that they saw his head brought to the city.
