SINIC AND HELLENIC UNIVERSAL STATES 653 porary East Roman reincarnation of the Roman Empire in Anatolia and Constantinople with Charlemagne's reincarnation of the Roman Empire in Gaul and Italy. But, to make our imaginary correspondence of post- Roman history with post-Han history complete, we must also endow the eighth-century East Roman Empire, which we are imagining Charlemagne's hypothetical Gallo-Roman supplanter to have annexed, with a vastly wider dominion than the modest combination of an Anatolian citadel with a Constantinopolitan bridgehead that had actually been inherited by Charlemagne's contemporaries Constantine VI and his mother Irene from their predecessor Leo Syrus. We must imagine the East Roman Empire of Charlemagne's day to have been coextensive with the Roman Empire within the frontiers that had been recovered for it by Justinian, and we must imagine Justinian to have succeeded completely in attaining his objective of reconquering the Roman Em- pire's Visigothic, as well as its Ostrogothic and Vandal, successor-state. This series of imaginary successes would have to be substituted for so many historical failures in the political history of a post-Hellenic inter- regnum in order to credit Charlemagne's hypothetical supplanter with an imaginary achievement of the same order of magnitude as the actual performance of the Chinese empire-builder Sui W€n-ti; and, even then, we should find that we had not succeeded in bringing Charlemagne's imaginary Gallo-Roman heir completely into line with his mighty Far Eastern counterpart; for the combination of actually unachieved suc- cesses which we have placed to the credit of Charlemagne's imaginary heir still leaves the English successor-states of the Roman Empire in Britain beyond our preposterously exaggerated imaginary limits of the Holy Roman Empire, whereas the whole former domain of the Han Empire was duly reassembled in the realm that Sui Wen-til actually brought into being. The residual discrepancy resulting from the recalcitrant independence of Mercia and the other barbarian successor-states of the Roman Empire in Britain might perhaps be glozed over, but we must not flatter our- selves by supposing that, if we were to ignore this minor point, we should find ourselves at the end of our imaginary rewriting of post- Roman history if we were seriously intent on bringing it into line with the post-Han history of the Far East; for an avatar of the Han Empire that had been integrally reconstructed by Sui Wen-ti was preserved all but intact for the next 553 years (A.D. 589-1142) under successive Sui, T'ang, and Sung regimes,1 whereas Charlemagne's diadochi and epigoni actually proved incompetent to hold together even the fraction of the Roman Empire's former domain that Charlemajgne had managed to reassemble. To bring the course of Far Eastern history into conformity with the course of Western history, we must imagine the year A.D. 589 1 A stricter count would limit the duration of the Far Eastern avatar of a Sinic uni- versal state to a span of some three hundred years, since the main body of the Far Eastern World went through a spell of political disruption between the onset of the T'ang Dynasty's death-agonies in the last quarter of the ninth century of the Christian Era (see IV. iv. 86 and 87-88) and the establishment of the Sung Dynasty in A.D. 960 (see V. vL 306); and during this bout of anarchy sixteen border districts were ceded, between the years A.D. 927 and 937, to the Khitan transfrontier barbarians (see II. ii. lai; IV. iv. 86; V. v. 308; and V. vi. 3°7).
