to litel, weylaway the whyle,
Lasteth swich Ioye, y-thonked be Fortune!
That semeth trewest, whan she wol bygyle,
And can to foles so hir song entune,
That she hem hent and blent, traytour comune; 5
And whan a wight is from hir wheel y-throwe,
Than laugheth she, and maketh him the mowe.

From Troilus she gan hir brighte face
Awey to wrythe, and took of him non hede,
But caste him clene out of his lady grace, 10
And on hir wheel she sette up Diomede;
For which right now myn herte ginneth blede,
And now my penne, allas! With which I wryte,
Quaketh for drede of that I moot endyte.

For how Criseyde Troilus forsook, 15
Or at the leste, how that she was unkinde,
Mot hennes-forth ben matere of my book,
As wryten folk through which it is in minde.
Allas! That they sholde ever cause finde
To speke hir harm; and if they on hir lye, 20
Y-wis, hem-self sholde han the vilanye.

O ye Herines, Nightes doughtren three,
That endelees compleynen ever in pyne,
Megera, Alete, and eek Thesiphone;
Thou cruel Mars eek, fader to Quiryne, 25
This ilke ferthe book me helpeth fyne,
So that the los of lyf and love y-fere
Of Troilus be fully shewed here.

Incipit Quartus Liber.

Ligginge in ost, as I have seyd er this,
The Grekes stronge, aboute Troye toun, 30
Bifel that, whan that Phebus shyning is
Up-on the brest of Hercules Lyoun,
That Ector, with ful many a bold baroun,
Caste on a day with Grekes for to fighte,
As he was wont to greve hem what he mighte. 35

Not I how longe or short it was bitwene
This purpos and that day they fighte mente;
But on a day wel armed, bright and shene,
Ector, and many a worthy wight out wente,
With spere in hond and bigge bowes bente; 40
And in the herd,
