About this source
What it is
This is a biographical poem about Thomas Becket, written in Old French verse by Guernes de Pont-Sainte-Maxence, a travelling cleric. He composed it shortly after Becket's death in 1170, drawing on interviews with people who had known him, including his sister, and on an earlier account by Edward Grim, who witnessed the murder.
Why it matters
The poem was meant to be read aloud at Becket's tomb, showing how quickly his story became part of public devotion. It reveals how medieval writers built a saint's reputation using both eyewitness testimony and earlier texts, and how Becket's fame spread in the vernacular language, not just Latin.
Look closer
- Why might Guernes have wanted to interview people who actually knew Becket?
- What does it mean that this poem was read aloud at the tomb rather than just read privately?
- How might using eyewitness accounts shape the story differently than relying only on earlier writings?
