Excalibur - Forms and Etymologies

Forms and Etymologies

The name Excalibur apparently derives from the Welsh Caledfwlch which combines the elements caled ("battle, hard"), and bwlch ("breach, gap, notch"). Geoffrey of Monmouth Latinised this to Caliburnus (likely influenced by the medieval Latin spelling calibs of Classical Latin chalybs, from Greek "χάλυψ", "steel"), the name of Arthur's sword in his 12th-century work Historia Regum Britanniae. Caliburnus or Caliburn became Excalibur, Escalibor, and other variations when the Arthurian legend entered into French literature.

Caledfwlch appears in several early Welsh works, including the poem Preiddeu Annwfn and the prose tale Culhwch and Olwen, a work associated with the Mabinogion and written perhaps around 1100. The name was later used in Welsh adaptations of foreign material such as the Bruts, which were based on Geoffrey. It is often considered to be related to the phonetically similar Caladbolg, a sword borne by several figures from Irish mythology, although a borrowing of Caledfwlch from Irish Caladbolg has been considered unlikely by Rachel Bromwich and D. Simon Evans. They suggest instead that both names "may have similarly arisen at a very early date as generic names for a sword"; this sword then became exclusively the property of Arthur in the British tradition. Most Celticists consider Geoffrey's Caliburnus to be derivative of a lost Old Welsh text in which bwlch had not yet been lenited to fwlch. In Old French sources this then became Escalibor, Excalibor and finally the familiar Excalibur.

In Chretien de Troyes's Perceval, Gawain carries Escalibor and it is stated, "for at his belt hung Excalibor, the finest sword that there was, which sliced through iron as through wood" ("Qu'il avoit cainte Escalibor, la meillor espee qui fust, qu'ele trenche fer come fust."). This statement was likely picked up by the author of the Estoire Merlin, or Vulgate Merlin, where the author (who was fond of fanciful folk etymologies) asserts that Escalibor "is a Hebrew name which means in French 'cuts iron, steel, and wood'" ("c'est non Ebrieu qui dist en franchois trenche fer & achier et fust"; note that the word for "steel" here, achier, also means "blade" or "sword" and comes from medieval Latin aciarium, a derivative of acies "sharp", so there is no direct connection with Latin chalybs in this etymology). It is from this fanciful etymological musing that Thomas Malory got the notion that Excalibur meant "cut steel" ("'the name of it,' said the lady, 'is Excalibur, that is as moche to say, as Cut stele.'").
