Crapulia is a mythological region attached to hell, a Semi-Primary Land of vice and moral corruption. Its status is referential.
Joseph Horne, father of the figure of the second circle, mentions it as a land of vices and moral corruption. It exists as a semi-primary world attached to hell and forms part of the peripheral infernal geography. It is visible from the periphery of hell during the descent of the figure of the second circle, with desolate and gloomy landscapes. It belongs to the wider cosmology of the cycle, which links primary and secondary worlds to hell.
