A jester was a historical entertainer either employed to entertain a ruler or other nobility in medieval or Tudor times or was an itinerant performer who entertained common folk at fairs and markets. Jesters in medieval times are often thought to have worn brightly coloured clothes and eccentric hats in a motley pattern and their modern counterparts usually mimic this costume. In medieval times jesters entertained with a wide variety of skills, which could include songs, music, storytelling, acrobatics, juggling, and magic. Much of the entertainment was performed in a comic style and many jesters made contemporary jokes in word or song about people or events well known to their audiences.
