Suetonius includes Julius, and therefore his Twelve Caesars end with Domitian, the last of the Flavian family. With Nerva the “five good emperors” (so called) begin, but the “good Aurelius” was a persecutor. St. John, surviving the cruelty of Domitian, lived and died under Trajan.
The “vision of Constantine” is dated, at Treves, A.D. 312.
The Labarum became the Roman standard thenceforth.
The Dominical ordinance dates from Milan, June 2, A.D. 321.
He founds the city of Constantinople A.D. 324, convokes the Council of Nicaea A.D. 325.
