There is a common thread
In the garter of shame
Worn by the knight Gawain
And Dante’s hem of guilt
On purgatory’s mount
Same thread weaved Portia plies
Envy spun in her eyes
Still displayed most monstrous
When Othello is found jealous
This thread supplants its root
Grace seen in every shoot
The color of blessing
Borrowed for condemning
Mercy’s hue intensifies
When its truth man defies
