Depiction of “stoolball” in the Ghistelles Calendar (Flemish, ca. 1301).
Stoolball, a game played by both men and women, dates to at least the 11th century, and seems to have been a forerunner of cricket and baseball. The “stool” referred to a wooden stool set up behind the batsman, which he defended from a ball lobbed by an opposing player.
