A comic subject will not be handled in tragic verse: in like manner the banquet of Thyestes will not bear to be held in familiar verses, and such as almost suit the sock. Let each peculiar species[ of writing] fill with decorum its proper place. Nevertheless sometimes even comedy exalts her voice, and passionate Chremes rails in a tumid strain: and a tragic writer generally expresses grief in a prosaic style. Telephus and Peleus, when they are both in poverty and exile, throw aside their rants and gigantic expressions if they have a mind to move the heart of the spectator with their complaint.
