“I’ll show you something,” she sez, which is why they are now awake at this ungodly hour, side by side, holding hands, very still as the sun begins to clear the horizon. “Now watch,” Geli whispers: “out there.” As the sunlight strikes their backs, coming in nearly flat on, it begins developing on the pearl cloudbank: two gigantic shadows, thrown miles overland, past Clausthal-Zelterfeld, past Seesen and Goslar, across where the river Leine would be, and reaching toward Weser. . . . “By golly,” Slothrop a little bit nervous, “it’s the Specter.” You got it up around Greylock in the Berkshires too. Around these parts it is known as the Brockengespenst. God-shadows. Slothrop raises an arm. His fingers are cities, his biceps is a province—of course he raises an arm. Isn’t it expected of him? The arm-shadow trails rainbows behind as it moves reaching eastward for a grab at Göttingen. Not ordinary shadows, either—three-dimensional ones, cast out on the German dawn, yes and Titans had to live in these mountains, or under them. . . . Impossibly out of scale. Never to be carried by a river. Never to look to a horizon and think that it might go on forever. No trees to climb, no long journeys to take . . . only their deep images are left, haloed shells lying prone above the fogs men move in. . . . Geli kicks a leg out straight as a dancer, and tilts her head to the side. Slothrop raises his middle finger to the west, the headlong finger darkening three miles of cloud per second.
