“The man in black fled across the desert, and the gunslinger followed.”

The Symbolism of the Tarot (1913)
Context: And I saw another man.
Tired and lame he dragged himself along the dusty road, across the deserted plain under the scorching rays of the sun. He glanced sidelong with foolish, staring eyes, a half smile, half leer on his face; he knew not where he went, but was absorbed in his chimerical dreams which ran constantly in the same circle. His fool's cap was put on wrong side front, his garments were torn in the back; a wild lynx with glowing eyes sprang upon him from behind a rock and buried her teeth in his flesh. He stumbled, nearly fell, but continued to drag himself along, all the time holding on his shoulder a bag containing useless things, which he, in his stupidity, carried wherever he went.
Before him a crevice crossed the road and a deep precipice awaited the foolish wanderer. Then a huge crocodile with open mouth crawled out of the precipice. And I heard the voice say:--
"Look! This is the same man."
I felt my head whirl.
