Palla (Italian for ball) is a traditional Tuscan ball game played in villages between Siena and Grosseto. It is also called palla EH! (or pallaeh!) because players call out eh! before serving. Small handmade balls contain a lead pellet wrapped in rubber and wool with a leather cover. The game is played by facing teams who strike (not catch) the ball with either a bare or gloved hand. Courts are marked out with painted lines on town streets, but there is no net, and players can move between sides. Adjacent buildings, objects, and sometimes spectators, are considered "in play." Play does stop for oncoming automobiles. Similar to real tennis, a second bounce can result in a "chase" rather than an outright point, marked in chalk where the ball stops rolling. Scoring is identical to that of tennis (15-30-40-game). In the variant called pallaventuno (or palla 21) each game counts as 7, and a set is won with three games (7 for the first, 14 for the second, and 21 for the third, hence the name given to the game). In the other variant, games are simply counted in progression (game 1, game 2). Pallacorda (or palla della corda) is an extinct form of the game where a cord was strung across the street. Pisa, Prato, Rome, Siena, and various Tuscan towns still have streets named via Pallacorda or via Della Corda. Historical significance Palla is of interest to those who study the history of tennis, as it provides some insight into the development of the more contemporarily popular sport. Given the similarities of scoring and the use of chases, it is highly likely palla and tennis share a common sporting ancestor, the various games of palla being more primal in form. The fact that real tennis was originally played without racquets is well documented. The name of the sport in French is jeu de paume, or game of the palm (of the hand). However, the development of the net is documented less well. In real tennis the net is also referred to sometimes as "the line." Palla eh! uses only a line painted on the ground to mark territory, and this is probably all it was originally. The cord was added for pallacorda probably just to keep the players on their respective sides of the court, and a ball that went under the cord, yet across the line, was probably
