Another version of soccer, called "calcio," was played in Florence since at least 1410. No less than 27 men on each team played the game on a huge sandpit, trying to send the ball towards designated goals. In doing so, players were allowed to use their hands, making the game a mixture of violent rugby and soccer.
In 1580 Giovanni de' Bardi, A Florentine count, published the official rules of calcio. Several of these rules, such as the halfway line, the wearing of team colors, referees and referee assistants and specific playing positions, match those of modern soccer.
