In reply to Trangia:
I think most of us on here could do a pretty good job with the Canterbury Tales:
" Whilom (once), as olde stories tellen us,
Ther was a duc that highte (if you know German, think laterally for that one) Theseus;
Of Atthenes he was lord and governour,
And in his tyme swich (think of the w as 'double u' and say aloud (no - it's not 'sewage', more Scots 'sich')) a conquerour,
That gretter was ther noon under the sonne.
Ful many a riche contree hadde he wonne,
What with his wysdom and his chivalrie;"
By this time, English was becoming more simplified and codified, although pronunciation was still quite different from today.
Old English, on the other hand, is pretty tough going for us these days:
"Hwæt. We Gardena in geardagum,
þeodcyninga, þrym gefrunon,
hu ða æþelingas ellen fremedon.
Oft Scyld Scefing sceaþena þreatum,
monegum mægþum, meodosetla ofteah,
egsode eorlas."
