The stranger was of exceedingly picturesque, and even melodramatic aspect. He was clad in a voluminous cloak, that seemed to be made of a buffalo’s hide, and a pair of those goat-skin breeches, with the hair outward, which are still commonly worn by the peasants of the Roman Campagna. In this garb, they look like antique Satyrs; and, in truth, the Spectre of the Catacomb might have represented the last survivor of that vanished race, hiding himself in sepulchral gloom, and mourning over his lost life of woods and streams.

Furthermore, he had on a broad-brimmed, conical hat, beneath the shadow of which a wild visage was indistinctly seen, floating away, as it were, into a dusky wilderness of mustache and beard. His eyes winked, and turned uneasily from the torches, like a creature to whom midnight would be more congenial than noonday.

On the whole, the spectre might have made a considerable impression on the sculptor’s nerves, only that he was in the habit of observing similar figures, almost every day, reclining on the Spanish steps, and waiting for some artist to invite them within the magic realm of picture. Nor, even thus familiarized with the stranger’s peculiarities of appearance, could Kenyon help wondering to see such a personage, shaping himself so suddenly out of the void darkness of the catacomb.

“What are you?” said the sculptor, advancing his torch nearer. “And how long have you been wandering here?”

“A thousand and five hundred years!” muttered the guide, loud enough to be heard by all the party. “It is the old pagan phantom that I told you of, who sought to betray the blessed saints!”

“Yes; it is a phantom!” cried Donatello, with a shudder. “Ah, dearest signorina, what a fearful thing has beset you in those dark corridors!”

“Nonsense, Donatello,” said the sculptor. “The man is no more a phantom than yourself. The only marvel is, how he comes to be hiding himself in the catacomb. Possibly our guide might solve the riddle.”

The spectre himself here settled the point of his tangibility, at all events, and physical substance, by approaching a step nearer, and laying his hand on Kenyon’s arm.

“Inquire not what I am, nor wherefore I abide in the darkness,” said he, in a hoarse, harsh voice, as if a great deal of damp were clustering in his throat. “Henceforth, I am nothing but a shadow behind her footsteps. She came to me when I sought her not. She has called me forth, and must abide the consequences of my reappearance in the world.”

“Holy Virgin! I wish the signorina joy of her prize,” said the guide, half to himself. “And in any case, the catacomb is well rid of him.”
