The humorous side of Dutch culture of the 17th century is obscured by a change that took place around 1670. Religious treatises and books of manners warning against laughter contributed to a new image, that of the humorless Calvinist Dutch. Based on a manuscript containing some 2000 jokes, the lost laughter of the Golden Age is reconstructed and analyzed. Most jokes are crude and obscene, and they throw a new light on attitudes towards sexuality, religion, and other aspects of life.
