  The picture before which they paused represented one of those ruined fountains so common to Italy. Francesca gazed upon it as if it had been an old friend: many a time, beside such a one, with its curved and broken marble, had she wreathed the acanthus that hung around it, the green and trailing foliage so profuse in the South, into shapes even more fanciful than those which once suggested the Corinthian capital.
