one of arthur's knights of the round table in Le Morte DeArthur according to thomas Mallory

I think it represents there being no where to rest and an overturn of hierarchy, but it is for you to interpret how you want.
The part of "Morte d'Arthur" that involves an element of the supernatural is when King Arthur is taken to Avalon by the sorceress Morgan le Fay after being wounded in battle. This mystical realm is where Arthur is said to rest until he is needed again.
Sir Mordred stabs Arthur in the head during their battle in "Le Morte D' Arthur". The wound is fatal, and Arthur presumably passes away a short while later.
It was obviously written in he 15th century because Mallory was born in 1405 and died in 1471. What is not so clear is the exact year that it was written in.
