“Yes, Monsieur, the Ruling Being of Mars has wings. He flies, passing from one continent to another like a spirit, all around his world, although he is unable to move beyond the vestiges of its atmosphere. I see them flying over the plains and cities, in the gilded air that they have there–for although it was believed in former times that the Martian sky is red while ours is blue, it is actually yellow: a beautiful, golden yellow.

Guy de Maupassant, 1887
