To be sure, the drama of passion which this book depicts has no particularly Roman features, and nothing was farther from my thoughts than to trace a picture of the society so local, so traditional, which exists between the Quirinal and the Vatican. The drama is not even Italian, for the scene might have been laid, with as much truth, at Venice, Florence, Nice, St. Moritz, even Paris or London, the various cities which are like quarters scattered over Europe of the fluctuating ‘Cosmopolis,’ christened by Beyle: ‘Vengo adesso da Cosmopoli’. It is the contrast between the rather incoherent ways of the rovers of high life and the character of perennity impressed everywhere in the great city of the Caesars and of the Popes which has caused me to choose the spot where even the corners speak of a secular past, there to evoke some representatives of the most modern, as well as the most arbitrary and the most momentary, life. You, who know better than any one the motley world of cosmopolites, understand why I have confined myself to painting here only a fragment of it. That world, indeed, does not exist, it can have neither defined customs nor a general character. It is composed of exceptions and of singularities. We are so naturally creatures of custom, our continual mobility has such a need of gravitating around one fixed axis, that motives of a personal order alone can determine us upon an habitual and voluntary exile from our native land. It is so, now in the case of an artist, a person seeking for instruction and change; now in the case of a business man who desires to escape the consequences of some scandalous error; now in the case of a man of pleasure in search of new adventures; in the case of another, who cherishes prejudices from birth, it is the longing to find the “happy mean;” in the case of another, flight from distasteful memories. The life of the cosmopolite can conceal all beneath the vulgarity of its whims, from snobbery in quest of higher connections to swindling in quest of easier prey, submitting to the brilliant frivolities of the sport, the sombre intrigues of policy, or the sadness of a life which has been a failure. Such a variety of causes renders at once very attractive and almost impracticable the task of the author who takes as a model that ever-changing society so like unto itself in the exterior rites and fashions, so really, so intimately complex and composite in its fundamental elements. The writer is compelled to take from it a series of leading facts, as I have done, essaying to deduce a law which governs them. That law, in the present instance, is the permanence of race. Contradictory as may appear this result, the more one studies the cosmopolites, the more one ascertains that the most irreducible idea within them is that special strength of heredity which slumbers beneath the monotonous uniform of superficial relations, ready to reawaken as soon as love stirs the depths of the temperament. But there again a
