The young Marchese Ludovico di Castelmare had in the early part of the evening lounged into the Circolo, as was the habit of most of those of his class, seniors as well as juniors; but he had, as had been correctly reported to his uncle, very shortly left it without saying a word to any one as to how he intended to dispose of his evening. The Marchese Ludovico flattered himself, as people are apt to flatter themselves in similar cases, that his absence would be little noted, and that his reticence would suffice to leave all Ravenna in ignorance as to the errand on which he was bound when he left the Circolo. So far was this from being the case, however, that there was not one, at all events among the younger men, whom he left behind him, who did not know perfectly well where he was gone; and that his uncle, when by the unforeseen accident that has been related he was made aware of his absence from the club, was at no loss to guess what he had done with himself. But in order that the reader may have a like advantage, it will be necessary to mention very briefly, some circumstances which occurred previously to the period referred to in the former chapters. Some months before the time of Signor Ercole Stadione's journey to Milan, a wandering Englishman had arrived at Ravenna, and having spent three or four days in examining with much interest the wonderful wealth of Mosaics of the fourth, fifth, and sixth centuries, still preserved in the churches of the ancient capital of the Exarchs, had continued his route to Venice. There, in the gallery of the Academia, his attention had been attracted by a female student, who was engaged in copying a canvas of Tintoretto. As it so happened that the traveller was a competent judge of such matters, he was struck by the goodness of the work, especially when considered in connection with the appearance of the artist. She was evidently very young,--a slim, slender girl, whose girlish figure looked all the more willow-like from the simple plainness, and what seemed to the Englishman the insufficiency, of her clothing. For the weather, though not so severe as when it had half frozen Signor Ercole Stadione, was already very cold,--cold enough to have depopulated the gallery of its usual crowd of copying artists. At some distance from the young girl's easel, sitting in a corner lighted up by a stray ray of sunshine, there was an old woman busily knitting,--probably the girl's mother, or protectress. And besides those two, and the Englishman, and a lounging attendant wrapped in his cloak, there was no other soul in the gallery.
