In the "Clouds" of Aristophanes, Just Discourse, in prescribing the rules
and proprieties which should in govern the education and conduct of the
healthy young man says:

"You shall rise up from your seat upon your elders' approach; you shall
never be pert to your parents or do any other unseemly act under the
pretence of remodelling the image of Modesty. You will not rush off to
the dancing-girl's house, lest while you gaze upon her charms, some whore
should pelt you with an apple and ruin your reputation."

"This were gracious to me as in the story old to the maiden fleet of foot
was the apple golden fashioned which unloosed her girdle long-time girt."
Catullus ii.

"I send thee these verses recast from Battiades, lest thou shouldst
credit thy words by chance have slipped from my mind, given o'er to the
wandering winds, as it was with that apple, sent as furtive love token by
the wooer, which out-leaped from the virgin's chaste bosom: for, placed
by the hapless girl 'neath her soft vestment, and forgotten--when she
starts at her mother's approach, out 'tis shaken: and down it rolls
headlong to the ground, whilst a tell-tale flush mantles the cheek of the
distressed girl." Catullus 1xv.

"But I know what is going on, and I intend presently to tell my master;
for I do not want to show myself less grateful than the dogs which bark
in defence of those who feed and take care of them. An adulterer is
laying siege to the household--a young man from Elis, one of the Olympian
fascinators; he sends neatly folded notes every day to our master's wife,
together with faded bouquets and half-eaten apples." Alciphron, iii, 62.
