Plutarch Quaestiones Convivales 5.8.2

[2] This discourse we liked indifferently well. But whereas Empedocles has thus written, I understand well (said I) the epithet given to pomegranates, because that at the end of autumn, and when the heats begin to decrease, they ripen the fruit; for the sun will not suffer the weak and thin moisture to thicken into a consistence until the air begins to wax colder; therefore, says Theophrastus, this only tree ripens its fruit best and soonest in the shade. But in what sense the philosopher gives the epithet ὑπέρφλοια to apples, I much question, since it is not his custom to strive to adorn his verses with varieties of epithets, as with gay and florid colors. But in every verse he gives some dilucidation of the substance and virtue of the subject upon which he treats; as when he calls the body encircling the soul the mortal-encompassing earth; as also when he calls the air cloud-gathering, and the liver full of blood.
