Then 'gan he strait unvail the mirrour bright,
The which fair Una gave him heretofore,
Ere he as yet, with Paynim foe to fight,
For foreign land had left his native shore.
This in his careful breast he always bore,
And on it oft would cast his wary eye;
For it by magick framed was of yore,
So that no falshood mote it well abye,
But it was plainly seen, or fearfully did fly.
