January 314 - December 335
His entire Pontificate took place during the reign of the Roman Emporer Constantine the Great, beginning within a year of the signing of the Edict of Milan (February 313) through which Christianity went from being a persecuted fatih to the official religion of the Roman Empire. Great new churches built in Rome during this time, endowed with splendid gifts by the Emperor and consecrated by Pope Sylvester, include the basilica and the baptistery of Saint John Lateran, Saint Peter’s, Saint Laurence-outside-the-walls and Santa Croce in Gerusalemme. Contrary to popular legend, he did not baptise Constantine. Buried originally in a cemetery-church he had built over the catacomb of Priscilla.
May 254 - 2 August 257

22 July 260 - 26 December 268
Probably of Greek origin, he was the immediate successor of the martyred Pope Sixtus II.
