[37] As, according to Tacitus, _Ann._ xv. 25 (comp. Dio, lxii. 22), Nero dismissed graciously the envoys of Vologasus, and allowed them to see the possibility of an understanding if Tiridates appeared in person, Corbulo may in this case have acted according to his instructions; but this was rather perhaps one of the turns added in the interest of Corbulo. That these events were brought under discussion in the trial to which he was subjected some years after, is probable from the statement that one of the officers of the Armenian campaign became his accuser. The identity of the cohort-prefect, Arrius Varus, in Tacitus, _Ann._ xiii. 9, and of the primipilus, _Hist._ iii. 6, has been without reason disputed; comp. on _C. I. L._ v. 867. [38] In Ziata (Charput) there have been found two inscriptions of a fort, which one of the legions led by Corbulo over the Euphrates, the 3d Gallica, constructed there by Corbulo’s orders in the year 64 (_Eph. epigr._ v. p. 25). [39] Nero intended _inter reliqua bella_, an Ethiopian one (Plin. vi. 29, comp. 184). To this the sending of troops to Alexandria (Tacitus, _Hist._ i. 31, 70) had reference. [40] As the aim of the expedition both Tacitus, _Hist._ i. 6, and Suetonius, _Ner._ 19, indicate the Caspian gates, _i.e._ the pass of the Caucasus between Tiflis and Vladi-Kavkas at Darial, which, according to the legend, Alexander closed with iron gates (Plin. _H. N._ vi. 11, 30; Josephus, _Bell. Jud._ vii. 7, 4; Procopius, _Pers._ i. 10). Both from this locality and from the whole scheme of the expedition it cannot possibly have been directed against the Albani on the western shore of the Caspian Sea; here, as well as at another passage (_Ann._ ii. 68, _ad Armenios, inde Albanos Heniochosque_), only the Alani can be meant, who in Josephus, _l. c._ and elsewhere appear just at this spot and are frequently confounded with the Caucasian Albani. No doubt the account of Josephus is also confused. If here the Albani, with consent of the king of the Hyrcanians, invade Media and then Armenia through the Caspian gates, the writer has been thinking of the other Caspian gate eastward from Rhagae; but this must be his mistake, since the latter pass, situated in the heart of the Parthian kingdom, cannot possibly have been the aim of the Neronian expedition, and the Alani had their seats not on the eastern shore of the Caspian but to the north of the Caucasus. On account of this expedition the best of the Roman legions, the 14th, was recalled from Britain, although it went only as far as Pannonia (Tacitus, _Hist._ ii. 11, comp. 27, 66), and a new legion, the 1st Italic, was formed by Nero (Suetonius, _Ner._ 19). One sees from this what was the scale on which the project was conceived.
