Two variations called "The Entire City" (1935 and 1936) by the German Surrealist painter Max Ernst (1891–1976). I have no doubt that this city is an abandoned ruin, large dark and menacing, a remnant of a ancient times.
I've seen things you people wouldn't believe.
Attack ships on fire off the shoulder of Orion.
I watched C-beams glitter in the dark near the Tannhauser gate.
All those moments will be lost in time, like tears in rain.
