The Canterbury Tales: The Knight's Tale
How we cite our quotes:
And whan that Theseus hadde seyn this sighte
Unto the folk that foghten thus echon
He cryde, 'Hoo! namoore, for it is doon.
I wol be trewe juge, and no partie;
Arcite of Thebes shal have Emelie,
That by his fortune hath hir faire ywonne!'
Theseus emphasizes here that he is an impartial judge, "no partie," and is careful to declare the winner of the competition publically to everyone. These concerns, for a public and impartially-refereed competition, were the ones that prompted him to decree the joust in the first place.
