17. Vopiscus in Hist. August. p. 230. [Tacit. c. 13.] Zosimus, l. i. [c. 63] p. 57. Zonaras, 1. xii. [c. 28] p. 637 [ed. Paris; p. 608, ed. Bonn]. Two passages in the Life of Probus (p. 236, 238 [Vopisc. Probus, c. 8 and 12]) convince me that these Scythian invaders of Pontus were Alani. If we may believe Zosimus (1. i. [c. 64] p. 58), Florianus pursued them as far as the Cimmerian Bosphorus. But he had scarcely time for so long and difficult an expedition.
