Through Common Era

Instead of cups, other types of covers can be used, such as bowls or hats. The shell game con is a rogue variant of the cups and balls used as a confidence trick.

History

The effect, also known as acetabula et calculi, was performed by Roman conjurers as far back as two thousand years ago, as referred to in Seneca's 45th Epistle to Lucilius:

Sic ista sine noxa decipiunt quomodo praestigiatorum acetabula et calculi, in quibus me fallacia ipsa delectat. Effice ut quomodo fiat intellegam: perdidi lusum.

Translation:

Such quibbles are just as harmlessly deceptive as the juggler's cup and dice, in which it is the very trickery that pleases me. But show me how the trick is done, and I have lost my interest therein.

One popularly circulated picture, thought to date from 2500 B.C. from the walls of a burial chamber in Beni Hasan, Egypt, shows two men kneeling over four inverted bowls. It was taken by early Egyptologists Wilkinson and Newberry as evidence that the cups and balls effect, or its related deceptive gambling game, thimblerig, possibly dates back to Ancient Egypt. Because of its context, modern Egyptologists regard the image as a game using pots or cups but details of the game are unknown. The illustration is unique in ancient Egyptian art, so whether or not the game utilizes sleight of hand trickery may never be known unless a future discovery produces a similar image in a more explanatory context.
