The headword is illustrated by both of the quotations given.
[1] Menander Protector fr. 9.1 Blockley (102-103), on John (Justin's envoy to the Persians in 567; cf. PLRE IIIa s.v. Ioannes(81)) broaching to Chosroes the idea of transferring Suania to the Romans. On emperor Justin II see iota 449 generally. On the Persian king Chosroes II see chi 418. On Suania see alpha 2811 note. Suania was strategically important to the Romans, because the Persians could use it as the base for an attack on Lazike (cf. kappa 1979), establish a naval presence on the Black Sea, and threaten Byzantion itself; cf. Blockley (255 note 43).
[2] Menander Protector fr. 5.3 Blockley (50-51), on the Antae leader and envoy to the Avars, Mezamer (cf. PLRE IIIb s.v. Mezamerus), assassinated (ca. 558/560) forthwith by his hosts. On the Antae (Antes, Antai), a warrior tribe of controversial ethnicity living in the area northwest of the Black Sea, see Louth (110, map) and Oxford Dictionary of Byzantium s.v. Antae. On the Avars see alpha 18 generally.
