About this source

What it is

The Raphael Rooms are a set of papal reception rooms in the Vatican, decorated with frescoes by Raphael and his workshop beginning in 1508. One room, the Sala di Costantino, was painted after Raphael's death by his assistants and tells the story of Constantine's life: his vision of the cross, his victory at the Milvian Bridge, his baptism by Pope Sylvester I, and his legendary 'Donation' granting lands to the papacy.

Why it matters

These frescoes were commissioned by Popes Julius II, Leo X and Clement VII to show Christianity triumphing over paganism, using Constantine's story to support the authority and prestige of the papacy. The figures of Sylvester were even given the face of the reigning pope, Clement VII, showing how history was used to flatter living rulers.

Look closer

  • Why would popes want to decorate their own palace with scenes from Constantine's life?
  • What does it mean that the painters gave Pope Sylvester the face of a later, living pope?
  • How reliable is a painted story like this as evidence of what actually happened to Constantine?
