There is a consensus of expert opinion that cricket may have been invented during Saxon or Norman times by children living in the Weald, an area of dense woodlands and clearings in southeast England. The first reference to cricket being played as an adult sport was in 1611, and in the same year, a dictionary defined cricket as a boys' game. There is also the thought that cricket may have derived from bowls, by the intervention of a batsman trying to stop the ball from reaching its target by hitting it away. Village cricket had developed by the middle of the 17th century and the first English "county teams" were formed in the second half of the century, as "local experts" from village cricket were employed as the earliest professionals. The first known game in which the teams use county names is in 1709.
