76 RENAISSANCES negative, unintentional, and unconscious, yet^ none the less valuable literary service had been performed by Mongol invaders us had been per formed in Greek Orthodox Christendom by the Frankiah conquerors o an East Roman Empire. Here, as there, an irruption of militant barbarian; had been a cultural and social as well as a political and military catastro- phe; here, as there, it had hit a small highly cultivated official class more severely than it had hit the uncultivated merchants, artisans, and peasan- try;1 here, as there, the shock dealt to this classically educated officialdom had broken 'the cake of custom'2 which this governing class had imposed on the lower strata of society; and, since, in a resuscitated Sinic and a resuscitated Hellenic universal state alike, the linguistic and literary custom hitherto upheld by the now crestfallen pandits had been the cult of a dead classical language and literature at the expense of a living vulgar tongue and the popular literature conveyed in it, the cultural effect, in China as in Greek Orthodox Christendom, was to liberate this popular literature from the incubus of a classical ideal and thereby give it a chance to invigorate itself by gaining access to the air and to the light. While the Chinese popular literature had the same history as its Modern Greek counterpart in these respects, it gave proof of a greater vitality by emulating the Medieval Western vernacular literature's feat of 'haunting the haunter*. As Hu Shih tells the story of how his own eyes were opened: *I found that the history of Chinese literature consisted of two parallel movements: there was the classical literature of the scholars, the men of letters, the poets of the imperial courts, and of the $itc; but there was in every age an undercurrent of literary development among the common people which produced the folk songs of love and heroism, the1 songs of the dancer, the epic stories of the street reciter, the drama of the village theatre and, most important of all, the novels. I found that every new form, every innovation in literature, had come never from the imitative classical writers of the upper classes, but always from the unlettered class of the country-side, the village inn and the market-place. I found that it was always these new forms and patterns of the common people that, from time to time, furnished the new blood and fresh vigour to the literature of the litterati, and rescued it from the perpetual danger of fossilisation, All the great periods of Chinese Literature were those when the master minds of the age were attracted by these new literary forms of the people and produced their best works, not only in the new patterns, but in close imitation of the fresh and simple language of the people, And such great epochs died away only when those new forms from the people had again * After the sack of Constantinople by the Crusaders in A,D. 1204, aotne of the pre- viously well-to-do Greek refugees from the sacked city -were ill-treated by the Greek rural population in the hinterland, who forcibly relieved them of the money that they had been able to' bring away with them, and gloated over the apectacle of grandees reduced to an equality with themselves on a common level of destitution, Th« poorer Greek inhabitants of Constantinople, who did not take flight, enriched themaelvea by buying from the Latin conquerors, at derisory prices, valuable articles of property that the Latins had plundered from the Greek purchasers* wealthy fellow-citteona (see the indignant comments on these proceedings in Nikitas Khoniatia* Khronihi Mfyisis, Epilogue on the Aftermath of the Catastrophe, chap. <, on no. *84»tf of I.
