The canals of Mars
A translation slip gave Mars its canal-building Martians

Giovanni Schiaparelli mapped a network of dark lines on Mars and called them canali, 'channels'. English readers took it as 'canals', something built, and for decades the public believed in Martian engineers. The lines turned out to be an optical illusion.
