The main event of the last full five-year period of this reign was the Gothic war (Hieron. An. 2347; Idat.; Oros. c. 28; Anon. Vales. p. 476; Eutrop. 10. 7; Vict. Cæs. p. 352; cf. Soz. 1. 26), undertaken in behalf of the Sarmatians (Anon. Vales. l.c.), carried on by Constantine II., and brought to an end April 20, 332 (cf. Clinton). The following year (333) Constans was made consul (Idat.; Hieron.; Prosper has 332; cf. Zos. 2. 35; Vict. Cæs. p. 161, &c.), and in 334 the remarkable (Anon. Vales.) incorporation of 300,000 Sarmatians into the empire (Anon. Vales. p. 476; Idat.; Hieron.; cf. Ammian. 17. 12, 18; 17. 13; 19. 12; V. C. 4. 6). This same year Calocærus revolted in Crete and was defeated (Anon. Vales. p. 476; Vict. Cæs. p. 161; Oros. c. 28; Hieron.). The following year (335) Constantine celebrated his tricennalia, and Dalmatius was made Cæsar (Idat.; Hieron. An. 340; Vict. Cæs. p. 161; Anon. Vales. p. 476; Chron. Pasch. p. 532; Vict. Epit. p. 51; Oros. c. 28), making now four Cæsars and a nondescript (cf. Anon. Vales. p. 476),—Constantine II, Constantius, Constans, Dalmatius, and Hannibalianus, among whom the world was now partitioned (Anon. Vales. p. 476; Zos. 2. 39; Vict. Epit. p. 52).
