The prayers of priests, nor times of sacrifice,

Embarquements all of fury, shall lift up

Their rotten privilege and custom ’gainst

My hate to Marcius: where I find him, were it

At home, upon my brother’s guard, even there,

Against the hospitable canon, would I

Wash my fierce hand in’s blood.

(i. x. 17.)

On this passage Coleridge comments:

I have such deep faith in Shakespeare’s heart-lore, that I take for granted that this is in nature, and not as a mere anomaly; although I cannot in myself discover any germ of possible feeling, which could wax and unfold itself into such a sentiment as this.
