The ship of fools (Modern German: Das Narrenschiff; Latin: Stultifera Navis) is an allegory, first appearing in Book VI of Plato's Republic, about a ship with a dysfunctional crew. The allegory is intended to represent the problems of governance prevailing in a political system not based on expert knowledge.
Images of the ship became popular, especially in German-speaking lands, especially after the publication of Sebastian Brant's satirical book Ship of Fools (1494), which served as the inspiration for Hieronymus Bosch's painting, Ship of Fools. Normally, the images show a ship crowded with men mostly wearing traditional jester or fool's costume with cloth ears ending in bells, many quarreling, drinking, and fighting. In the book a ship—an entire fleet at first—sets off from Basel, bound for the Paradise of Fools. In it, Brant conceives Saint Grobian, whom he imagines to be the patron saint of vulgar and coarse people. In literary and artistic compositions of the 15th and 16th centuries, the cultural motif of the ship of fools also served to parody the "ark of salvation", as the Catholic Church was styled.
