Calvin (Admonitio de Reliquiis) gives a long list of places claiming to possess one or more of the thorns which composed the Saviour's crown. To his list may be added Glastonbury Abbey, where was also the spear of Longius or Longinus, and some of the Virgin's milk.
Si l'espine non picque quand nai, A pene que picque jamai.
Proverb in Dauphine.
