For all his tresoun and trayn,   als I am trew lord!
Today Clarent and Caliburn   shall kithe them togeders
Whilk is keener of carfe   or harder of edge!
Fraist shall we fine steel upon fine weedes.
It was my darling dainteous   and full dere holden,
Keeped for encrownmentes   of kinges annointed;
On dayes when I dubbed   dukes and erles
It was burlich borne   by the bright hiltes;
I durst never dere it   in deedes of armes
But ever keeped clene   because of myselven.
For I see Clarent uncledde   that crown is of swordes,
My wardrope at Walingford   I wot is destroyed.

Alliterative Morte Arthur
