Grocott & Ward, comps. Grocott’s Familiar Quotations, 6th ed. 189-?.
Potent
Most potent, grave, and reverend signiors,
My very noble and approved good masters,
That I have ta’en away this old man’s daughter,
It is most true; true, I have married her;
The very head and front of my offending
Hath this extent, no more.
Shakespeare.—Othello, Act I. Scene 3. (To the Senate.)
