Jack, also known as Jack o' the Green is a character who appears in May Day celebrations around England. It is thought that the tradition started in the 16th or 17th century when people made garlands to celebrate the arrival of May. These garlands became more elaborate and the practice arose of covering a person in leaves.
In certain areas, such as Cheltenham, Jack became associated with chimney sweeps!
