Everybody is acquainted with Excalibur. Everybody who is worth knowing at any rate. The sword that is inextricably fused with peril, legend, myth, grand battles, knights, chivalry, gory warfare and mystical adventure. It bears an illustrious and regal name, befitting of its status and reputation. Excalibur. Poetic, evocative, rolls off the tongue.
It may interest you to know that King Arthur also had a helmet by the name of Goswit, and a shield called Pridwen. Archaic and paganistic titles, exuding a sort of rugged magic. One can well imagine such weapons facing the likes of dragons in order to save damsels in distress.
Probably even less familiar to you will be King Arthur's spear. His spear whose name was Ron.
'The bold Arthur took Ron in his hand, the valiant king advanced the stout shaft'
This is why I took Middle English. As if the idea of naming weaponry wasn't ridiculous and mad enough. Ron the spear. Ingenious.
But, hey, if it does does the job and is plunged into the breasts of the heathen hordes, cleaving their hearts in twain, hacking out guts and entrails, and making the battlefields run red with blood, then what the hell does it matter if it's got a less than resplendent name? It could be worse. It could be called Wayne.
