I’d venture to say there’s a glutton hiding inside all of us. Some of us are gluttons for food, some for money, and some for that enchanting nectar – alcohol. Alcohol addiction has plagued humankind since we first discovered the joys of that sweet, fermented liquid. The ancient Greeks were no less immune to gluttonous drinking and Pythagoras of Samos cleverly designed a cup that would expose the greedy: the Pythagorean Cup.
A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation. Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. If they fill the cup only to that level, the imbiber may enjoy a drink in peace. If they exhibit gluttony, however, the cup spills its entire contents out of the bottom (onto the lap of the immodest drinker).
