The Nicene Age
Who Sylvester I of Rome was
Bishop of Rome for over two decades (314–335) spanning Constantine’s whole Christian reign — the great basilicas of the Lateran, St Peter’s, and St Paul’s rose during his episcopate. Too aged or too cautious to travel, he was represented at Nicaea by two presbyters, Vitus and Vincentius, who signed before most bishops. His quiet historical record was later buried under the most consequential forgery of the Middle Ages — the ‘Donation of Constantine,’ with its legend of his baptizing the emperor — which this archive marks plainly as fiction. The real Sylvester governed the transition it fantasized.
Also listed in the bishops of Rome.
