La Main Chaude was a parlour game of forfeits fashionable in the 17th century, and a popular subject for Dutch genre painters of the time (handjeklap in Dutch). Translated it means "Hot Cockles" or the "Hot Hand", also known as the "Red Hand" and "Slaps". The game is believed to have originated in the Middle Ages, and can be seen on ivories and miniatures of the period.
One player, the "penitent," hides his face in the lap of a second (called the "confessor," a referee who monitors the game) and places his hand flat behind his back. In turn, other players slap the penitent on the hand or the bottom, and he tries to identify who hit him. The player who lets himself be discovered then becomes the penitent.
This amusing Female-led painting titled Ladies and Gentlemen Playing La Main Chaude was thought to be by Hieronymus or Jeroom Janssens (1624 - 93), nicknamed Den danser, a Flemish genre painter, but is now considered to be the work of a follower of the artist. It can probably be dated by the clothes to about 1655.
