One origin has English shepherds in the Middle Ages bowling or rolling balls of rags or wool at a target, often the sheep paddock's wicket gate. Other shepherds defended it with their crooked staffs. But it is unlikely one single game evolved into modern cricket.
Edward II (1300s) and Oliver Cromwell (1600s) are attributed with wielding a bat, and the first recorded game was in Kent, England, in 1646.
The first written Laws of Cricket in 1744 said the ball must weigh 5 oz. to 6 oz. In the 1770s, the weight became 5 1/2 oz. to 5 3/4 oz., and the circumference was 8 13/16 inches to 9 inches.
Cricket balls have a cork core that is covered with tightly wound string, and two- or four-piece leather case. The slightly raised sewn seam is the most important part of the ball, producing its unpredictable movement off the pitch.
Hand-making cricket balls, even up to first class and test quality, is still a cottage industry in the Indian subcontinent.
