"Come with me," Raphael cried, "since you have nothing better to do--pardon me, my friend--since such an excursion is exactly what you would enjoy. We will ride to-morrow morning to Ostia and charter some fishing craft there for the sail to Porto d'Anzio." I accepted the invitation, glad to visit this favourite seaside resort of the Roman emperors. Even before we landed we could see the ruins of their villas deep in the clear waters of the bay, fish gliding through arches and the seaweed waving its pennons from the walls. The cliff at the back of the town presented a most impressive appearance, being pierced by great arched openings like the portals of a Roman bath. And such, indeed, they were, for on the promontory above had been the gardens of the imperial villa, and from them staircases carven in the rock descended to this subterranean chamber, which at full-tide the sea, rushing through a long canal, once converted into a swimming-pool. The great cavern had been dry for centuries, for the tides had piled their own sandy dykes before it, and the vaulting had fallen bringing with it a portion of the garden of the imperial villa and burying its statues beneath the debris. It was here that excavations had been begun, and as we entered the cave from the beach, our way was bordered by the fragments of many a column and capital, by broken vases and by headless statues. But none of these attracted us, for in the centre of the chamber, perfectly illumined by a shaft of light which fell upon it slantwise from the chasm in the roof, was the most superb statue which our eyes, nay, which any human vision had ever beheld. Apollo's very self stood there, god-like in superhuman majesty, as though he were an archangel who had alighted from his flaming chariot to lift a threatening hand against the workers of iniquity. I cannot describe the profound impression which this discovery made upon Raphael. He was raised to the seventh heaven, as on that memorable night at Siena, and while he gazed at the statue a mysterious voice, clear but freighted with intense emotion, chanted the _Hymn to Apollo_ to which we had listened at Chigi's villa. At first we could not tell from whence it came but looked about in startled surprise. Presently, however, a branch of laurel fell through the opening in the roof, the song ended in a peal of laughter, and we knew that some one was looking down upon us from the old Roman garden. No one but Imperia could sing like that, and when Raphael exclaimed. "It is the same song, the same singer that we heard at Cetinale." I cried out. "The same, the same. She is celebrating the discovery of Apollo." "She promised to come to me when I had found Apollo," he said, and bounded up the rude stairway. Even then I did not realise that though Raphael had recognised the voice he still supposed that it was Maria Dovizio who had sung on that evening, and that it was she whom he now believed he was about to meet.
