"The Prologue is well--the Epilogue worth the whole--such is my criticism--read--stare--and conclude your friend mad--tho' a more Christian supposition would be--(what's true at the same time) that my ideas are frozen, much more frigid than the play;--but allowing that--and although I confess myself exceeding cold, yet I have warmth enough to declare myself yours sincerely."
— Sancho, Charles Ignatius (1729-1780)
(I.xl, pp. 107-8; p. 79 in Carretta)
