A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup which forces its user to imbibe only in moderation. Credited to Pythagoras cup, it allows the user to fill the cup with wine up to a certain level. If the user fills the cup only to that level, the imbiber may enjoy a drink in peace. If the imbiber exhibits gluttony, however, the cup spills its entire contents out the bottom (onto the lap of the immodest drinker).
