X. B (ii) (a), ANNEX IV THE RELATION, IN RENAISSANCES OF UNI- VERSAL STATES, BETWEEN EFFECTIVENESS OF EVOCATION AND DEGREE OF GEOGRA- PHICAL DISPLACEMENT IN a preceding Annex to this chapter,1 in which we have compared the renaissances of the Sinic and Hellenic universal states, we have found that the renaissance of the Sinic universal state in the main body of the Far Eastern World was remarkably more effective than was the renais- sance of the Hellenic universal state hi either Western or Orthodox Christendom, and also that, as between these two renaissances of the Roman Empire in the histories of the two Christian Hellenistic civiliza- tions, its renaissance in the shape of an East Roman Empire in the main body of Orthodox Christendom fell less far short than its renaissance in the shape of a Holy Roman Empire in the West fell short of the standard of effectiveness set by the renaissance of the Ts'in and Han Empire in the shape of the Sui and T'ang Empire. These findings suggest, as far as they go—and they are, of course, based on a consideration of only three cases—that the effectiveness of the evocation of an- antecedent society's universal state varies in direct ratio with the tenacity of the original universal state in surviving, or with its persistence in rallying, during the death agonies of the moribund society of which it was a tardy political embodiment, and in inverse ratio with the degree of the geo- graphical displacement of the domain of the affiliated civilization, in whose history the renaissance takes place, from the domain of its defunct predecessor. In Sinic and Far Eastern history the dissolution of the Posterior Han Empire at the turn of the second and third centuries of the Christian Era was ephemerally retrieved during the years A.D. 280-317 by a reunion of the whole of its former territory under the rule of 'the United Tsin'; and, when, thereafter, a nascent Far Eastern Society emerged out of a post-Sinic interregnum, its domain was virtually coextensive with its Sinic predecessor's, even though, within this domain, the Yellow River Basin, which had been the Sinic Civilization's cradle, was now rivalled in importance by a Yangtse Basin which had been incorporated into the Sinic World only in the course of its Time of Troubles and its universal state. In Hellenic and Orthodox Christian history a Roman Empire which had dissolved at the turn of the fourth and fifth centuries of the Christian Era in the West survived till the turn of the sixth aad seventh centuries in the central and eastern provinces with a tenacity comparable to the persistence of a temporarily dissolved Sinic universal state in reconstituting itself for a further spell under the auspices of the United Tsin. On the other hand the domain of the Orthodox Christian Society that emerged thereafter out of a post-Hellenic interregnum, i On pp. 649-81, above.
