Geoffrey Chaucer - The Love Unfeigned

O YONGE fresshe folkes, he or she,
In which that love up groweth with your age,
Repeyreth hoom from worldly vanitee,
And of your herte up-casteth the visage
To thilke god that after his image
Yow made, and thinketh al nis but a fayre
This world, that passeth sone as floures fayre.

And loveth him, the which that right for love
Upon a cros, our soules for to beye,
First starf, and roos, and sit in hevene a-bove;
For he nil falsen no wight, dar I seye,
That wol his herte al hoolly on him leye.
And sin he best to love is, and most meke,
What nedeth feyned loves for to seke?

Geoffrey Chaucer
