A quiet, ongoing debate and battle goes on over Glastonbury's history, and it has done so for a long time.
The key issue concerns what is accepted as admissible historical evidence, and how traditions are interpreted. There is some propaganda too, with excessive claims made both on historians' and mystics' sides. Also evidence has been destroyed, not available, covered over, unresearched or kept quiet.
On this site we use the word 'traditions' to indicate legendary aspects of history which cannot conclusively be verified. Two of Glastonbury's biggest traditions concern Joseph of Arimathaea and King Arthur. We use the word 'history' to refer to evidentially sound and accepted events.
