External witness

Who Emperor Constans was

Constantine's youngest son and the Nicene party's imperial shield: it was Constans who forced the Council of Serdica, threatened his brother Constantius with war unless Athanasius was restored, and — with his brothers — wrote to the hermit Antony 'as to a father.' Killed in Magnentius's coup of 350, and mourned by the exiles he had protected; the assassination handed the whole empire, and the church, to Constantius II.

Also listed in non-christian witnesses and roman emperors.
