Holy Grail: from legend to quest

The story or discovery

Chrétien de Troyes presents the Grail as a serving vessel; medieval narratives give it different forms.

What the sources establish

Robert de Boron connects the Grail with the Last Supper and Joseph of Arimathea.

What needs distinguishing

These sources document literary history, not the archaeological identification of a cup. Matthew 26 describes a shared cup at a meal; it does not narrate a knightly quest. Reading the accounts alongside each other shows how a tradition makes new connections. An artwork records that reception without proving the provenance of the object it depicts.

A question to explore

What changes when a mysterious object in a romance becomes a relic in a tradition?
