Spurning carnal desire and earthly temptations all his life, the mystic Othlo is now in the care of his brother monks including the odious and semen-filled Wolkbart. Despite the spare walls which surround him, he frolics with Holy Dionysius in the Garden of Head-bearers (each carries his own head for eternity), descends from the island of Heaven, visits a brothel patronized by fallen angels, and witnesses the souls of the once gluttoinous wealthy fighting over scraps of rotting crabmeat in a ditch in Hell.

The third and final book in a series about mankind's desire to conquer nature, Visions and Temptations follows Awake and Sublunar. In each novel, a great if imperfect mind facesis failed by the inevitable demise of the body.
