or Durindana. Orlando's sword, given him by his cousin Malagigi. It once belonged to Hector, and was made by the fairies. It could cleave the Pyrenees at a blow. N. B.—In French romance Orlando is called Roland, Malagigi Mangis, and the sword durandal or durindal (See Sword.)
Nor plaited shield, nor tempered casque defends, Where Durindana's trenchant edge descends.
