The concept of "life on Mars" and "Martian Fever" was not incited in the pages of the tabloid magazine Weekly World News—but actually reaches much further back to 1877—with Italian astronomer Giovanni Schiaparelli. The astronomer himself was not to blame: a single word in his report—canali, which is Italian for “channels”—was misinterpreted to mean "canal" once translated into English. In Schiaparelli’s time, telescopes became more advanced and powerful, allowing him to make detailed maps of the planet’s surface. At the time of this mapping, Mars was in “opposition,” bringing the planet into close alignment with Earth for easier observation. While creating his maps, however, Schiaparelli fell victim to an optical illusion. He perceived straight lines crisscrossing the surface of the planet, which he included in his records, assigning them the names of rivers on Earth. These were the canali—and the source of a misunderstanding which morphed into a self-perpetuating legend about intelligent, ancient, canal-building Martian lifeforms.
