Beyond Lies the Wub by Philip K. Dick

Ten sequels followed over the next three decades, further extending his vision of Barsoom and adding other characters. The first five novels are in the public domain in U. The world of Barsoom is a romantic vision of a dying Mars. Writers and science popularizers like Camille Flammarion , who were convinced that Mars was at a later stage of evolution than Earth and therefore much drier, [1] took the ideas farther and published books like Les Terres du Ciel , which contained illustrations of a planet covered with canals. Burroughs gives credits to him in his writings, and goes as far as to say that he based his vision of Mars on that of Flammarion.
