The scene is inspired by a visionary text written by an Irish monk that was widely disseminated throughout Europe, telling the story of a journey into the Afterlife undertaken by the sinful knight Tundale, who, after falling into a long, deep sleep, is guided through the next world by an angel. The infernal geography, reminiscent of a danse macabre, is dominated by a colossal mountain in the shape of a human head. Each of the micro-scenes illustrates the torments and symbols connected to the seven deadly sins: the black rat represents lust; the monkey, lies; the coins, avarice; the wine vat with bobbing nuns and friars, lust. Depicted on the right, in a huge helmet, are the punishments reserved for the slothful, wrathful, and gluttonous.
