Bocce's origins date back to 5000 BC, where evidence of Egyptian cave paintings depict Nile Delta boys playing something that resembles bocce (although who's to say it wasn't soccer, rugby, or something entirely different?). The game caught on with the Romans and Greeks during those early days, with the resourceful players substituting coconuts, melons, carved wood, and bound rags for bocce balls. At one time, bocce was popular with the social elite, the game of Emperors and Senators— like something you'd picture the Windsors wearing their plaids and letting loose (with the exception of Prince Harry, who sheds the plaid altogether when doing his take on letting loose). As Roman rule spread far and wide, bocce turned up in ancient Britain, France, Germany, Spain, and as far east as Persia.
