Lucia Claudia was surprised to receive from the aged Fulvia, one of her brother’s bondwomen, the sign which was to convey to her an intimation that she was the Christian to whom she and Cornelia were to intrust themselves. In that humble old woman she had not expected to find a Christian, but she returned the signal, upon which Fulvia, with great animation, embraced her, saying, “Lady Lucia, my prayers for thee are heard. Go, for God is with thee, and fear nothing. Yea, be strong and courageous in the Lord, trusting the brethren in the household, who will guide thee faithfully to the Church beneath, in the hope that the doctrines thou wilt hear there to-night will lead thee to the Church of the blessed one above.”

“Thou art then a Christian,” replied Lucia.

“Noble Lady, I am a deaconess of the Church, and many of this household, both male and female, are worshippers also of the Lord Jesus Christ.”

Lucia looked at Cornelia in mute surprise, and then at Fulvia.

“Yes, Lady Lucia, even in Cæsar’s household there are men who are ready to die for that faith the emperor persecutes. Already ‘its sound has gone forth into all lands, and its words to the end of the earth,’ and ‘the gates of hell shall not prevail against it.’ Dare you trust the slaves who have become the freed-men of the Lord, and have embraced Christianity at a time when its converts are assailed with fire and sword? If so, I will come to you in the dead hour of midnight as your guide.”

“I dare,” replied Lucia Claudia, and she looked at Cornelia. “Thou, too, wilt go with me, my nurse?”

“I follow thee, my foster-child, to death,” was the answer of the humble but truly attached friend. Fulvia smiled benignantly upon the new converts and withdrew.

In the still hour of midnight Fulvia, veiled in the Christian fashion, entered the apartment where Lucia and Cornelia anxiously awaited her coming, enveloped also in their veils and palliums. Without uttering a syllable, Fulvia motioned them to follow her. Softly she glided along the corridor, till she gained the door that opened into the offices belonging to the house. Then she entered the court which was appropriated to the slaves, and, threading the mazes of a covered passage, struck sharply against the wall, when, to the surprise of her trembling companions, a large stone sliding back revealed a flight of steps, feebly illuminated by the light of a lamp, that glimmered in the distance like a faint star. Lucia did not perceive by what means the solid stone had receded from its place; to her it seemed the work of magic art, and she shuddered and clung to the arm of her nurse.

Cornelia, more self-possessed, had noticed that it was drawn up by two men, aided by some powerful machinery, and that it was cautiously and instantly replaced. With Fulvia for a guide, the new converts traversed many winding passages, sometimes turning to the right or left, till they overtook some persons with torches in their hands, who gave them the sign of brotherhood, and in whom they recognised a part of the household. These slaves greeted Lucia Claudia with more than usual respect, and, falling back, permitted her to pass them, with the exception of Glaucus, the freedman of Julius Claudius, who held a torch in his hand, and now preceded the sister of his lord. Perceiving that Lucia was not entirely without fear, he occasionally addressed her, explaining that she was in the Arenaria, and that many of the passages she crossed led under the principal streets and palaces of Rome, and that the converts of the new faith had pierced openings from their own houses, as the slaves in her brother’s household had done. He bade her observe how curiously these vaults were supported without the aid of masonry, and that they were seemingly as firm as when hollowed many centuries before. Suddenly he ceased speaking, but, striking sharply with his staff against the wall, paused for an instant, when a groove was suddenly drawn back, and a stream of light flashed upon the eyes of Lucia and her nurse, and Linus, in his white stole, came forward and welcomed them to his church. Then the slaves who had followed Lucia Claudia arranged themselves on each side of the chapel, the women covered with their veils, the men uncovered. Each person hid their faces in their hands and said a short prayer. Linus stood before the altar awaiting the gathering together of his flock, who kept flowing in from the opposite entrance. The short delay permitted Lucia to examine the curious cavern that the Christians had dedicated to the worship of their God, which here was of width and length capable of holding several hundred persons; the roof was supported by its own strength, without the aid of pillars; it was rather low than lofty; the walls were pierced with niches, filled in with marble or tiles; the same emblems adorned these tablets as Fulvia had displayed that evening. From the inscriptions upon them Lucia discovered that they were the tombs of Christian martyrs, for the palm and the cross were the distinguishing marks of a Christian sepulchre in that day. The altar was the tomb of a martyr; thus even the dead in Christ seemed to appeal to the living, that they also might follow the example of their constancy.

The prayers, the hymns, the spiritual worship of the primitive Church, the eloquence of its oratory, found its way to the bosom of the new converts, and when they came forward at the termination of the service to offer themselves as candidates for baptism, they were greeted by the whole assembly with the utmost affection. The slaves of Julius’s household shed tears of joy. Linus then addressed to them a short but impressive admonition. He told them that the times were perilous, and that those who embraced the faith of Jesus must first count the cost, since they warred not only with flesh and blood, and with spiritual wickedness in high places, but with the whole powers of darkness. That they were bidden to take up the cross, not counting their lives dear unto them, but forsaking all to follow Christ.
