Plutarch Comparationis Aristophanis et Menandri compendium 2

[2] But now Menander’s phrase is so well turned and contempered with itself, and so everywhere conspiring, that, while it traverses many passions and humors and is accommodated to all sorts of persons, it still shows the same, and even retains its semblance in trite, familiar, and every-day expressions. And if his master do now and then require something of rant and noise, he doth but (like a skilful flutist) set open all the holes of his pipe, and then presently stop them again with good decorum and restore the tune to its natural state. And though there be a great number of excellent artists of all professions, yet never did any shoemaker make the same sort of shoe, or tireman the same sort of visor, or tailor the same sort of garment, to fit a man, a woman, a child, an old man, and a slave. But Menander hath so addressed his style, as to proportion it to every sex, condition, and age; and this, though he took the business in hand when he was very young, and died in the vigor of his composition and action, when, as Aristotle tells us, authors receive most and greatest improvement in their styles. If a man shall then compare the middle and last with the first of Menander’s plays, he will by them easily conceive what others he would have added to them, had he had but longer life.
