Rainbow Mars is a 1999 science fiction short story collection by American writer Larry Niven. It contains six stories of Hanville Svetz, five previously published and the longest, "Rainbow Mars", written for the collection. The setting of the Svetz stories is Earth in the distant future. The hereditary leader of the Earth, known as the Secretary General, is an inbred imbecile. In order to maintain the interest of the Secretary, different factions in the capitol use their advanced science to amuse him. Svetz's section uses time travel in an attempt to bring back long extinct animals from Earth's past. Unbeknownst to Svetz and his team, they are actually travelling back into fictional pasts, and returning with mythical creatures.

Contents

• "Rainbow Mars". With a new Secretary General who is interested more in space travel than animals, Svetz uses his time machine to visit Mars, which he finds populated by the creations of Edgar Rice Burroughs, Ray Bradbury, C. S. Lewis, H. G. Wells, and Stanley G. Weinbaum. The story began as a collaboration with Terry Pratchett; a number of his ideas remain in the final draft, mainly the use of Yggdrasil.^[1]
• "Get a Horse!", first published in The Magazine of Fantasy and Science Fiction, October 1969. Svetz is sent back in time to capture a horse, but brings back a unicorn instead.
• "Bird in the Hand", first published in The Magazine of Fantasy and Science Fiction, October 1970. Svetz is sent to get a roc, but returns with an ostrich, which he reverse engineers into a roc.
