In the print, "Temptation of the Idler" (also called "The Dream of the Doctor"), Dürer depicts a man, a doctor, sleeping next to a large ceramic stove. The doctor, dressed in his robes, leans against a pillow and seems comfortable, asleep, and at ease. Next to his head, floats some sort of demonic figure, which blows air into the doctor’s ear with a bellows – a tool normally used to stoke the flames of a fire. Beside the sleeping doctor stands a nude woman, gesturing toward the doctor with her right hand while holding a ring in her left. The ring, together with the companionship of Eros, gives away her identity: this is Venus, the Roman goddess of love, beauty, sex and fertility. 

In the scene, the activating agent for the dream seems to be the demon with the bellows, which is blowing air into the doctor’s ear. The notion of demonic infiltration of the mind through the ear is a fairly common one in this era. Here we see a couple of examples in the works of contemporaries Lucas Cranach and Hans Holbein.
