I am unlikely to write much if any more poetry for a while. Anyway, here's an old english roses are red-type poem I wrote (I was a bit loose with the metre for it to properly be OE-alliterative-verse but that's really hard).
rōsan ond appellēaf, rēade ond hæwen bēoþ
gelīce wīcingum blōd, on bryme gespiled
sigle ic feohtan, mid mē scule þū cuman
Approximate translation:
Roses are red,
Violets are blue
Vikings' blood
Spilt on the sea too
I'm sailing to fight
with me you should come
(there wasn't a good way to make that last line fit the rhyme in modern english, oh well)
