A jester, court jester, or fool was historically an entertainer during the medieval and Renaissance eras who was a member of the household of a nobleman employed to entertain him and his guests. A jester was also an itinerant performer who entertained common folk at fairs and markets. Jesters are also modern day entertainers who resemble their historical counterparts. 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: principal ones included songs, music, and storytelling; additional ones included acrobatics, juggling, telling jokes, 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.
