At this moment one of the bands of marauders--the desperate criminals of famine and plague--who still prowled through the city, appeared in the street. Their trembling hands sought their weapons, and their haggard faces brightened, when they first discerned the Pagan and the girl; but as they approached nearer they saw enough in the figures of the two, at a glance, to destroy their hopes of seizing on them either plunder or food. For an instant they stood by their intended victims, as if debating whether to murder them only for murder's sake, when the appearance of two women, stealthily quitting a house farther on in the street, carrying a basket covered by some tattered garments, attracted their attention. They turned instantly to follow the bearers of the basket, and again Ulpius and Antonina were left alone on the river's bank. The appearance of the assassins had been powerless, as every other sight or event in the city, in arousing the faculties of Ulpius. He had neither looked on them nor fled from them when they surrounded him; but now when they were gone he slowly turned his head in the direction by which they had departed. His gaze wandered over the wet flagstones of the street, over two corpses stretched on them at a little distance, over the figure of a female slave who lay forsaken near the wall of one of the houses, exerting her last energies to drink from the turbid rain-water which ran down the kennel by her side; and still his eyes remained unregardful of all that they encountered. The next object which by chance attracted his vacant attention was a deserted temple. This solitary building fixed him immediately in contemplation--it was destined to open a new and a warning scene in the dark tragedy of his closing life. In his course through the city he had passed unheeded many temples far more prominent in situation, far more imposing in structure, than this. It was a building of no remarkable extent or extraordinary beauty. Its narrow porticoes and dark doorway were more fitted to repel than to invite the eye; but it had one attraction, powerful above all glories of architecture and all grandeur of situation to arrest in him those wandering faculties whose sterner and loftier aims were now suspended for ever; it was dedicated to Serapis--to the idol which had been the deity of his first worship, and the inspiration of his last struggle for the restoration of his faith. The image of the god, with the three-headed monster encircled by a serpent, obedient beneath his hand, was carved over the portico.
