Alas, I can take no credit for this ancient poetry, I had it sent to me, but this seemed like a proper Yuletide venue:

Incipit gestis Rudolphi rangifer tarandus
>
> Hwæt, Hrodulf readnosa hrandeor --
> Næfde þæt nieten unsciende næsðyrlas!
> Glitenode and gladode godlice nosgrisele.
> Ða hofberendas mid huscwordum hine gehefigodon;
> Nolden þa geneatas Hrodulf næftig
> To gomene hraniscum geador ætsomne.
> Þa in Cristesmæsseæfne stormigum clommum,
> Halga Claus þæt gemunde to him maðelode:
> "Neahfreond nihteage nosubeorhtende!
> Min hroden hrædwæn gelæd ðu, Hrodulf!"
> Ða gelufodon hira laddeor þa lyftflogan --
> Wæs glædnes and gliwdream; hornede sum gegieddode
> "Hwæt, Hrodulf readnosa hrandeor,
> Brad springð þin blæd: breme eart þu!"
>
>
> And the modern English translation:
>
> Here begins the deeds of Rudolph, Tundra-Wanderer
>
> Lo, Hrodulf the red-nosed reindeer --
> That beast didn't have unshiny nostrils!
> The goodly nose-cartilage glittered and glowed.
> The hoof-bearers taunted him with proud words;
> The comrades wouldn't allow wretched Hrodulf
> To join the reindeer games.
> Then, on Christmas Eve bound in storms
> Santa Claus remembered that, spoke formally to him:
> "Dear night-sighted friend, nose-bright one!
> You, Hrodulf, shall lead my adorned rapid-wagon!"
> Then the sky-flyers praised their lead-deer --
> There was gladness and music; one of the horned ones sang
> "Lo, Hrodulf the red-nosed reindeer,
> Your fame spreads broadly, you are renowned!"
