The Constitutum Silvestri is one of five fictitious stories known collectively as the Symmachian forgeries, that arose between 501 and 502 at the time of the political battle for the papacy between Pope Symmachus (498-514) and antipope Laurentius. The other four, the first two with similar themes to the Constitutum Silvestri, are: * Gesta synodi Sinuessanae de Marcellino * Gesta de Xysti purgation * Gesta de Polychronii episcopi Hierosolynitani accusation * Gesta Liberii papae
