English, old - sh.itjust.works

Whan that Aprille with his shoures soote, The droghte of March hath perced to the roote, And bathed every veyne in swich licóur Of which vertú engendred is the flour;
Is that Beowulf era English?

hwonne þæs esode eac swéoran hrūmas

(I used an online translator for the first line so probably horribly bastardized)
