Colley Cibber, An Apology for the Life of Mr. Colley Cibber…
“ Yet this is but one Light wherein the Excellence of an Actor can shine: But in Othello we may see him in the Variety of Nature: There the Actor is carried through the different Accidents of domestick Happiness and Misery, occasionally torn and tortur'd by the most distracting Passion that can raise Terror or Compassion in the Spectator. Such are the Characters that a Master Actor would delight in; and therefore in Othello I may safely aver that Booth shew'd himself thrice the Actor that he could in Cato. And yet his Merit in acting Cato need not be diminish'd by this Comparison. ”
