n8 RENAISSANCES though Elamite had no affinity with any previously known language, living or dead; and bilingual texts in Asshurbanipal's library1 enabled philologists who had already mastered a Semitic Akkadian language to interpret a Sumerian language which, like Elamite, had no known affinities, but which was of much greater historical importance than Elamite, since it proved to be the mother tongue of the creators of a Sumeric Civilization into whose heritage the speakers of Elamite and Akkadian had entered belatedly as proselytes. Perhaps the most remarkable of all the triumphs of a Modern Western Archaeology was the disinterment of civilizations that had not only been long since dead and buried but had fallen into complete oblivion. The Minoan Civilization and the Indus Culture, both of which had been disinterred within the present writer's lifetime in the Old World, and the Mayan Civilization in the New World, were the most notable cases of dead civilizations that had suffered this total eclipse; and the recapture of the marvellously accurate but formidably complicated Mayan system of chronological reckoning and notation was perhaps the greatest feat of archaeological skill so far achieved. The vividness of the life with which these dead, buried, and in some cases entirely forgotten civilizations were endowed in the consciousness of a latter-day Western Society that had succeeded in recapturing them was piquantly illustrated by the vitality of Ikhnaton's ghost, which, after a vitai pausa2 of more than thirty-two centuries' duration, aroused the same controversially conflicting feelings of sympathy and antipathy in Western academic circles in the nineteenth century of the Christian Era that the Egyptiac records testified to his having aroused in the ilesh in Egyptiac clerical circles when he was living, reigning, and innovating in the fourteenth century B.C. In thus establishing a third kind of contact between one civilization and another, the Modern Western archaeologists had done contem- porary Modern Western historians the invaluable service of raising the number of known civilizations to a figure at which it had become just feasible to make this species of human society a subject of comparative study.a (II) THE OCCASION OF THE DRAMA OF RENAISSANCES 'Encounters in the flesh' may be precipitated by deliberate acts of will —inspired by aggressiveness, piety, curiosity, or other incentives—on the part of one or more of the parties. Curiosity, for example, was the motive of Herodotus's, Marco Polo's, and Ibn Battutah*8 travels; piety the motive of Goethe's and Byron's, as well as Fa Hsien'a and Arculf a, pilgrimages; aggressiveness the motive of Alexander's, Dcmetrius'a, the Cid's, and Chingis' conquests. It is also possible, however, for these en- counters between contemporaries in the Space-dimension to come about by accident.
