Your two great eyes will slay me suddenly;
Their beauty shakes me who was once serene;
Straight through my heart the wound is quick and keen.

Only your word will heal the injury
To my hurt heart, while yet the wound is clean -
Your two great eyes will slay me suddenly;
Their beauty shakes me who was once serene.

Upon my word, I tell you faithfully
Through life and after death you are my queen;
For with my death the whole truth shall be seen.
Your two great eyes will slay me suddenly;
Their beauty shakes me who was once serene;
Straight through my heart the wound is quick and keen.

Geoffrey Chaucer
