The old man, without surprise at the advent of a young girl in blue velvet, took down the image, and explained to her its history in his slow, musical, Roman tongue. Even mademoiselle lent an ear of unwilling fascination to the tale. The little wooden figure, a foot in height, was San Donato. Behold, signorina mia, the beauty of the face, the robes tinted a soft rose, with ample gold margin, the aureole and palm of martyrdom in the hand. In the great Demidoff villa of San Donato a patron saint was placed in a niche above the portal of certain suites of apartments, as guardian spirit, by the builder. That brought good luck. The Russian prince is dead, signorina, and the nephew heir cast out the saints with quantities of other valuables for sale. For this reason poor San Donato, patron of the whole place, is now perched on a shelf in a little shop at Rome. Cecilia listened with sparkling eyes, and her head a trifle on one side. "San Donato shall be my saint," she cried, extending her hands. "Two hundred francs? I have more in my purse. You need not frown, mademoiselle; it is my pocket-money from my papa in America, to spend as I choose. Good-by, signor; I will come to see you again some time." The old shop-keeper looked after her a moment, then drew from under a chair a repast of dry bread and an onion, interrupted by the purchaser. "After all, San Donato might have brought me luck had I kept him longer," he muttered, draining the little flask of wine as he sat on the door-step, and musing with that curious mixture of avarice and regret at losing a treasure peculiar to the connoisseur. San Donato was carried along the street by his happy possessor somewhat in the fashion of a new doll. Mademoiselle hid his light under a bushel by laying a fold of shawl over his head and aureole. Cecilia's fancy was captivated by his history even more than by his pensive face and gorgeous robes. San Donato, deposed from his lofty estate in the palace of a Russian prince, should preside as guardian spirit of her home. The image was invested with the gifts of the good fairy as much as he embodied any religious symbol. _His mission was to avert evil._ The saint passed to a new shrine without attendant priests, acolytes, and banners, the swinging of censers, the tinkling of bells, as in the fine old days before Rome was a modern European capital. It was not even borne aloft on sailors' shoulders, like the silver statue of Our Lady at Marseilles, or the miracle-working black Madonna of Montenero at Leghorn. Instead, San Donato moved under the arm of a young girl, muffled in a shawl, skirting the bridge, the quay, the square, now in sunshine, now in shadow, and finally gained the Piazza di SS. Apostoli. Here he was conducted across a court adorned with mouldy statues, and vanished up a broad stairway.
