The magical
faerie sword wielded by
Arthur, the High King of
Albion (or Britan as it was later known) during his reign. Replaced the
sword drawn from a stone (which proved his parentage) for differing reasons - some tales say the sword shattered, others that
Merlin simply thought he needed a new one. Its scabbard was said to heal any wound, its blade to carve through any foe.
Middle English, Excalibur.
Old French, Escalibor.
Medieval Latin, Caliburnus.
Welsh, Caledvwlch.
Celtic, Kaleto.
