The Bridal of Triermain is a narrative poem in three cantos by Walter Scott, published anonymously in 1813. It is written in a flexible metre of four and three stress lines. Set in Cumberland, it recounts the exploits of a knight as he seeks to rescue a beautiful maiden, Gyneth, the illegitimate daughter of King Arthur, doomed by Merlin 500 years previously to an enchanted sleep inside a magic castle.
