Trigon (game)

• 1. Introduction

  ›

  Trigon was a ball game played by the ancient Romans, and it asked something unusual of its players: throw with your right hand, catch with your left, and never stop moving. The name comes from the Greek word trigōnos, meaning three-cornered or triangular, and the game may have arrived in Rome as a version of an older Greek game called trigōn. Three players stood at the points of a triangle, each holding a small, hard ball, and the object was to keep those balls flying between them at high speed without a drop. What did it take to be good at this game? What did it look like when someone played it badly? And who was keeping score, and how?

  ›

  Each player started with somewhere between three and six balls, all small and hard. The throwing arm was always the right, and catching was always done with the left. Players who could catch reliably with their left hand were considered admirable, because the skill involved was genuinely difficult. The point was to keep all the balls circling continuously at high speed, with no interruptions and no drops. The game had two known versions for how failure was judged. In one version, a player lost a point each time they failed to make a catch. Whoever had the fewest points at the end lost the match. In the other version, a single dropped ball ended the game immediately, and the player who missed it was declared the loser.

• 3. The Scorekeepers

  ›

  Alongside the three main players, called trigonali, there were assistants known as pilecripi. Their job was twofold: they tracked the score, and they chased down any ball that escaped the triangle. Keeping score in trigon was not straightforward. The standard method was to count successful passes, which rewarded skill and consistency. But a passage in the Satyricon by the Roman writer Petronius describes a game where the pilecripus counted something different entirely: the number of balls that fell to the ground rather than the number caught. Petronius may have intended this as a pointed joke at the expense of the player in question, or he may have been describing a genuine alternative scoring method. Either reading says something about how seriously Romans could take the game.

• 4. Trimalchio's Game

  ›

  Petronius's Satyricon contains the most detailed surviving description of what is almost certainly trigon in action, even though the text never uses the word. A bald old man named Trimalchio is playing with a pair of young, curly-haired slave boys. Several details mark Trimalchio as someone with no real investment in the game. He plays wearing his sandals, which suggests he is not prepared to move. He never bends down to retrieve a dropped ball. Instead, a servant stands ready with a large sack of fresh balls to replace any that hit the ground. When Trimalchio snapped his fingers mid-game, a slave brought water so he could wash his hands. When he finished, he dried his hands on the long curly hair of the young slave boys playing with him. The scene is rich with social texture: the slaves are there to serve the game and Trimalchio's comfort in equal measure, and Trimalchio's indifference to the rules underlines his status rather than diminishing it.

• 5. Roman and Greek Roots

  ›

  The word trigon points directly to the game's likely origins. Trigōnos in Greek means triangular or three-cornered, and Roman writers may have been describing a game that traveled from Greece into Roman culture and kept much of its structure intact. The Greek game called trigōn appears to be the direct ancestor. Whether the Romans adapted the rules or simply adopted them wholesale is not recorded, but the name itself suggests that the triangular formation of three players was the feature that most defined the game in the minds of both cultures. The ball used was small and hard, which made catching one-handed, especially with the non-dominant left hand, a mark of real ability.
