Reapers in fall must first calibrate and celebrate their spring. In 1972, Vesna Vulovic fell from the height of 33,330 ft in an exploding airplane onto a frozen mountain side and lived to tell the story. This (mis)fortune, registered as the highest free fall a human being has survived, was brought by a nominal coincidence: Vesna was not scheduled to be on the flight, but had been mixed up with another flight attendant of the same name. Every Vesna shares her name with the springtime goddesses of Slavic mythology who lived in palaces atop mountains enwrapped in magic circles where they discussed the fate of crops and of human beings.

Objects and humans fall because of gravity's pull. Free-falling closed rooms, however, will preclude the local observer inside them from differentiating between gravitational pull and floating in non-gravity.

Singing and springing Vesnas, descending down each February from their palaces to the valley, could only be heard by certain people. Perception is absolutely local (like death). Rituals, names, or numbers may serve to secure the recurrence of common universal units—seasons and whatnot. In return they must obliterate particularities and forget the fact that they did so. No spring is devoid of sacrifices and the sacrificed must not survive. Gravity of numbers is only put to an end by the number of gravities.
