Pathosformel: stored formulas of intense emotion
Antiquity coined fixed visual formulas for extreme states such as the maenad's frenzy, the nymph's windblown drapery and the lament over a dead hero, and these formulas keep the emotional charge of the moment they were created. Later artists who need to show intense feeling reach for these ready-made gestures instead of inventing new ones, so the ancient emotion returns through the borrowed form.
