Somnium
Johannes Kepler
 The story is the tale of Duracotus, who was the son of an Icelandic witch named Fiolxhilda. During his youth she banished Duracotus to Denmark 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 Lagrangian point 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.
