It was on a summer evening that two youths might be seen walking beside the banks of the Tiber, not far from that part of its winding course which sweeps by the base of Mount Aventine.  The path they had selected was remote and tranquil.  It was only at a distance that were seen the scattered and squalid houses that bordered the river, from amidst which rose, dark and frequent, the high roof and enormous towers which marked the fortified mansion of some Roman baron.  On one side of the river, behind the cottages of the fishermen, soared Mount Janiculum, dark with massive foliage, from which gleamed at frequent intervals, the grey walls of many a castellated palace, and the spires and columns of a hundred churches; on the other side, the deserted Aventine rose abrupt and steep, covered with thick brushwood; while, on the height, from concealed but numerous convents, rolled, not unmusically, along the quiet landscape and the rippling waves, the sound of the holy bell.

Of the young men introduced in this scene, the elder, who might have somewhat passed his twentieth year, was of a tall and even commanding stature; and there was that in his presence remarkable and almost noble, despite the homeliness of his garb, which consisted of the long, loose gown and the plain tunic, both of dark-grey serge, which distinguished, at that time, the dress of the humbler scholars who frequented the monasteries for such rude knowledge as then yielded a scanty return for intense toil.  His countenance was handsome, and would have been rather gay than thoughtful in its expression, but for that vague and abstracted dreaminess of eye which so usually denotes a propensity to revery and contemplation, and betrays that the past or the future is more congenial to the mind than the enjoyment and action of the present hour.

The younger, who was yet a boy, had nothing striking in his appearance or countenance, unless an expression of great sweetness and gentleness could be so called; and there was something almost feminine in the tender deference with which he appeared to listen to his companion.  His dress was that usually worn by the humbler classes, though somewhat neater, perhaps, and newer; and the fond vanity of a mother might be detected in the care with which the long and silky ringlets had been smoothed and parted as they escaped from his cap and flowed midway down his shoulders.

As they thus sauntered on, beside the whispering reeds of the river, each with his arm round the form of his comrade, there was a grace in the bearing, in the youth, and in the evident affection of the brothers—­for such their connexion—­which elevated the lowliness of their apparent condition.
