Brabantio questioning Othello as to the whereabouts of Desdemona...

“Damn'd as thou art, thou hast enchanted her; 
For I'll refer me to all things of sense, 
If she in chains of magic were not bound, Whether a maid so tender, fair and happy, 
So opposite to marriage that she shunn'd
 The wealthy curled darlings of our nation, 
Would ever have, to incur a general mock, 
Run from her guardage to the sooty bosom. Of such a thing as thou.”
