On a clear night in 1894, Percival Lowell looked through his telescope at his private observatory outside Flagstaff, Arizona, and saw exactly what he expected to see: the canals of Mars. They were not there. But he would spend two decades insisting they were, and in doing so lit a fire of imagination that science fiction is still burning today.
The Original Misunderstanding
The story begins with Italian astronomer Giovanni Schiaparelli, who in 1877 reported observing linear features he called canali — Italian for channels, a neutral geological term. Translated into English as canals, the word implied deliberate construction. Lowell seized on the mistranslation. Using his private fortune, he built the Lowell Observatory specifically to study Mars and spent years mapping what he believed were irrigation canals built by an advanced civilization to transport water from the polar ice caps.
The Legacy of a Beautiful Wrong Idea
Lowell was wrong about virtually everything. The canals were optical illusions — the brain's tendency to connect disconnected features into lines at the limits of resolution. But his romantic vision fired the imagination of a generation: H.G. Wells wrote The War of the Worlds, Edgar Rice Burroughs invented Barsoom, Ray Bradbury's Martian Chronicles traces directly to this vision.
The real Mars, revealed by spacecraft, turned out to be even more interesting than Lowell's fantasy: no canals, but an ancient ocean; no desperate engineers, but the chemistry of past habitability; no civilization, but the genuine possibility of microbial life. Lowell was wrong about Mars. But he was right that it was worth looking.
