[V. 3. 179.] Warburton says: The players, among their other innumerable absurdities, in the representation of this tragedy, make Richard say instead of ‘O coward conscience,’ ‘O tyrant conscience!’
He refers to Colley Cibber’s adaptation of Shakespeare’s play: ‘The Tragical History of King Richard III. Altered from Shakespear. By Colley Cibber Esq.’
