(Aww, it didn't keep the formatting)
A tale of Beowulf, Bairn of Ecgthew
aethling of the Geats, firey focus of fable.
Victories many, bought with bounty of blood.
Twin monsters, Grendel's mother and child
in the Scylding's land, brought low by sin
Time's riverbed, flows fleetingly fast
Until old king Beowulf, Bairn of Ecgthew
starcross'd lord, dreaded day of his death
faced a dragon, and greatest of god's geats
slew it quickly, protecting his land.
Ancient tale, fable of forefathers
of ancient prose, dense deep and dire.
Modern readers, ancient knowledge gone
will struggle much, History held in the heorot
cannot help them, since a heorot they lack.
thus unendowed, no strength for sound struggle
Will then fail, no meaning to them.
Knowledge of the past, if that ye seek
so ye desire, long lost lore
read knowing well, a challenging battle
Hazy and difficult, to enlighten yourself
but expect not, golden rings from the lord
facing the challenge, of this ancient tale.
