 for five years. Upon his return, she decided to share some of her secrets with him. She explained that her instructor had been a demon who dwelt on the Moon. During a Solar Eclipse, the lunar demons were able to travel between the Earth and the Moon via a bridge of darkness. The son decided he wanted to make this journey, and so he was transported to the Moon by demons.

To ease his journey he was given a drowsing draught and moist sponges to hold under his nose. He was carried to the point of neutral gravity between the Earth and Moon, then allowed to drift down to the lunar surface. Thus the author understood some of the effects of gravity and the need for environmental protection above the atmosphere.

Nearly 20 years later, Kepler added the dream framework, and after another decade, he drafted a series of explanatory notes reflecting upon his turbulent career and the stages of his intellectual development. The book was edited by his heirs, including Jacob Bartsch, after Kepler's death in 1630.

Publication

It was published posthumously in 1634 by his son, Ludwig Kepler. Similarities with real life led to Kepler's own mother being arrested on charges of witchcraft.
