Drawings of Mars showing its 'canals' and polar ice caps, 1907. 
Drawings of Mars showing its 'canals' and polar ice caps, 1907. These drawings are from observations made at the Lowell Observatory, Flagstaff, Arizona, USA, on 8-12 July, 1907. The American astronomer Percival Lowell (1855-1916) theorised that a Martian civilization, faced with climate change, had built the canals to transport water from the planet's ice caps to irrigate crops. In fact the canals did not exist; they are now thought to have been optical illusions possibly caused by dust storms.
