Sir Hruodland and Durandal :
Sir Hruodland (or Roland) was the chief paladin of Charlemagne.
His sword, Durandal is said to contain within its golden hilt one tooth of Saint Peter, blood of Saint Basil, hair of Saint Denis, and a piece of the raiment of the Blessed Virgin Mary.
Local folklore claims Durendal still exists, preserved in Rocamadour, France.
