Roman Emperors and the \"King\" title

[D B Campbell]

Incidentally, the Excerpta Valesiana may be wrong to name him rex regum; no other source gives him this "Persian" title. (Another source calls him rex regum Ponticarum gentium, which is significantly different: "king of kings of the Pontic people".)

Anyone following this thread might be interested in Karin Mosig-Walburg's theory that Hannibal(l)ianus held a "special position" overseeing the client kingdoms of Sophene, Iberia and the Lazi. Pontus fell within the remit of Constantius (II), who governed Asia.
