2. Κούπα Πυθαγόρα

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). All these Pythagorean Cups exist at all the types of works-shading of Ifigeneia Ceramis,(IF1,IF2,IF3. . .IF17)
