Calcio fiorentino (also known as calcio storico "historic football") is an early form of football that originated in 16th-century Italy. Once widely played, the sport is thought to have originated in the Piazza Santa Croce in Florence. Here it became known as the giuoco del calcio fiorentino ("Florentine kick game") or simply calcio; which is now also the name for association football in the Italian language. The game may have started as a revival of the Roman sport of harpastum.
The modern version of calcio allows tactics such as head-butting, punching, elbowing, and choking but sucker punches and kicks to the head are banned.[1] It is also prohibited for more than one player to attack an opponent. Any violation leads to being thrown out of the game.
