In honor of our best and greatest rulers, Gaius Aurelius Valerius Diocletian, our pious, lucky, and unconquered emperor, and Marcus Aurelius Valerius Maximian, our pious, lucky, and unconquered emperor, and to Flavius Valerius Constantius and Galerius Valerius Maximianus, our noblest caesars, has Aurelius Asclepiades, praeses of the province of Arabia, ordered to build Castra Praetorium Mobene from its foundations.
So, this would have been a post on the Strata Diocletiana, the military road Diocletian built to defend the Eastern border?
“Flavius Valerius Constantius”
Emperor Constantine’s father?
