After a half-hour's walk, they came to a winding staircase cut in the rock, which led them a zigzag course up through galleries and grottos looking out through curious windows and loop-holes upon the sea, till finally they emerged at the old sculptured portal of a shady garden which was surrounded by the cloistered arcades of the Convent of Saint Agnes. The Convent of Saint Agnes was one of those monuments in which the piety of the Middle Ages delighted to commemorate the triumphs of the new Christianity over the old Heathenism. The balmy climate and paradisiacal charms of Sorrento and the adjacent shores of Naples had made them favorite resorts during the latter period of the Roman Empire,--a period when the whole civilized world seemed to human view about to be dissolved in the corruption of universal sensuality. The shores of Baiae were witnesses of the orgies and cruelties of Nero and a court made in his likeness, and the palpitating loveliness of Capri became the hot-bed of the unnatural vices of Tiberius. The whole of Southern Italy was sunk in a debasement of animalism and ferocity which seemed irrecoverable, and would have been so, had it not been for the handful of salt which a Galilean peasant had about that time cast into the putrid, fermenting mass of human society. We must not wonder at the zeal which caused the artistic Italian nature to love to celebrate the passing away of an era of unnatural vice and demoniac cruelty by visible images of the purity, the tenderness, the universal benevolence which Jesus had brought into the world. Some time about the middle of the thirteenth century, it had been a favorite enterprise of a princess of a royal family in Naples to erect a convent to Saint Agnes, the guardian of female purity, out of the wrecks and remains of an ancient temple of Venus, whose white pillars and graceful acanthus-leaves once crowned a portion of the precipice on which the town was built, and were reflected from the glassy blue of the sea at its feet. It was said that this princess was the first lady abbess. Be that as it may, it proved to be a favorite retreat for many ladies of rank and religious aspiration, whom ill-fortune in some of its varying forms led to seek its quiet shades, and it was well and richly endowed by its royal patrons. It was built after the manner of conventual buildings generally,--in a hollow square, with a cloistered walk around the inside looking upon a garden. The portal at which Agnes and her grandmother knocked, after ascending the winding staircase cut in the precipice, opened through an arched passage into this garden. As the ponderous door swung open, it was pleasant to hear the lulling sound of a fountain, which came forth with a gentle patter, like that of soft summer rain, and to see the waving of rose-bushes and golden jessamines, and smell the perfumes of orange-blossoms mingling with those of a thousand other flowers.
