Yet there are faults, which we should be ready to pardon: for neither does the string [always] form the sound which the hand and conception [of the performer] intends, but very often returns a sharp note when he demands a flat; nor will the bow always hit whatever mark it threatens. But when there is a great majority of beauties in a poem, I will not be offended with a few blemishes, which either inattention has dropped, or human nature has not sufficiently provided against. What therefore [is to be determined in this matter]? As a transcriber, if he still commits the same fault though he has been reproved, is without excuse; and the harper who always blunders on the same string, is sure to be laughed at; so he who is excessively deficient becomes another Choerilus; whom, when I find him tolerable in two or three places, I wonder at with laughter; and at the same time am I grieved whenever honest Homer grows drowsy But it is allowable, that sleep should steal upon [the progress of] a long work.
