“Ninety-two is the atomic number of uranium, and Tulse Luper Suitcases aims at nothing more or less ambitious than a history of the twentieth century as the “uranium century”. It is also a number that Greenaway has constantly associated with Luper: it is the number of maps in A Walk Through H , which can also be found in Luper’s book Some Migratory Birds of the Northern Hemisphere , and it recurs throughout The Falls , firstly as its basic structural unit in terms of the number of biographies of the characters affected by the Violent Unknown Event (VUE) and then within the film itself. The counting system of ninety-two elements originates in Greenaway’s miscounting of the ninety parts of John Cage’s Indeterminacy Narrative . Greenaway’s work has always been preoccupied with such systems of classification: “If his work is tirelessly systems-based, his systems – his games, lists, alphabets, countings, variously simple, intricate, playful, philosophical, comic – are above all ironic, self-referential, never in conflict with the surplus of material available for classification, a surplus which they display as much as they discipline” (Woods 22).”
