[2] Procopius (Jones, et al., pp. 742-743) led a rebellion against Valens, Roman emperor (364-378 CE); OCD(4) s.v., omicron 764.
[3] A central-western region of Asia Minor (present-day Turkey); though its boundaries are fluid, in general it is bounded by Lydia (lambda 783) on the west, Bithynia to the north, by Pisidia (pi 1643) and Lycaonia (lambda 796) to the south, and by the Tuz Gölü (Salt Lake) to the east. See OCD(4) s.v. Phrygia; tau 555 (gloss).
[4] Eunapius fr.32 FHG (4.26); Blockley, Procopius fr. 34.5. The quotation appears to be interrelated with epsilon 936 (so Bernhardy), mu 1048, and pi 380 (Blockley, p. 138); cf. mu 1056. Niebuhr suggested replacing sunh/pteto with sunhpei/geto, was pressing down upon together.
