the island of Levania," which is Earth's Moon. According to the daemon, there is a pathway between the island of Levania and Earth. When the pathway is open, daemons can take humans to the island in four hours. The journey is a shock to humans, so they are sedated for the trip. Extreme cold is also a concern on the trip, but the daemons use their powers to ward it off. Another concern is the air, so humans have to have damp sponges placed in their nostrils in order to breathe. The trip is made with the daemons pushing the humans toward Levania with great force. At the Lagrangian point between the Earth and the Moon, the daemons have to slow the humans down lest they hurtle with great force into the Moon. After describing the trip to Levania, the daemon notes that daemons are overpowered by the Sun. They dwell in the shadows of the Earth, called Volva by the inhabitants of Levania. The daemons can rush to Volva during a solar eclipse, otherwise they remain hidden in shadows on Levania. After the daemon describes other daemons' behavior, she goes on to describe Levania. Levania is divided into two hemispheres called Privolva and Subvolva. The two hemispheres are divided by the divisor. Privolva never sees Earth (Volva), Subvolva sees Volva as their moon. Volva goes throughout the same phases as the actual Moon. The daemon continues the descriptions of Subvolva and Privolva. Some of these details are scientific in nature such as: how eclipses would look from the Moon, the size of the planets varying in size due to the Moon's distance from the Earth, an idea about the size of the Moon and more. Some details of Levania are science fiction such as: descriptions of the creatures that inhabit Subvolva and Privolva, plant growth on each side, and the life and death cycle of Levania. The dream is cut short in the middle of the description of the creatures of Privolva. Kepler wakes up from the dream because of a storm outside. He then realizes that his head is covered and he is wrapped in blankets just like the characters in his story. Publication history Development Somnium began as a student dissertation in which Kepler defended the Copernican doctrine of the motion of the Earth, suggesting that an observer on the Moon would find the planet's movements as
