Miscellany
Observing Mars through his telescope in 1877, Milanese astronomer Giovanni Schiaparelli saw oceans and canali, meaning channels. The latter was mistranslated into English as canals, implying Martian-made waterways, and an amateur astronomer named Percival Lowell soon began publishing books pointing to these as evidence of life on Mars. By 1910 photographic technology had advanced sufficiently to debunk his extrapolated theories.
