The precursor to tennis first used what instead of rackets?
“Jeu de Paume,” the precursor to tennis, began with the simplest racket imaginable: the human hand. While this old game, originally developed in the 11th and 12th centuries, eventually adopted rackets, the name “Jeu de Paume,” or “Game of the Palm,” stuck around, a handy reference for remembering the game’s roots.
