Conclusion.

Then ende I thus, sith I may do no more.
I yeve hit up for now and evermore,
For I shal never eft putten in balaunce
My sekernes, ne lerne of love the lore.
But as the swan, I have herd seyd ful yore,
Ayeins his deth shal singen his penaunce,
So singe I here my destinee or chaunce,
How that Arcite Anelida so sore
Hath thirled with the poynt of remembraunce.
