At the time that the two pontiffs were leaving the Curia Hostilia, a female slave was making her way along the Appian Road, about two miles from her home. She wore over her usual dark dress a coarse laena, which served to conceal a basket filled with provisions which she carried on her arm. Turning off to the left, she followed a slightly beaten track, scarcely perceptible to the ordinary eye. After pursuing it for some distance, she again crossed a track of wild and barren ground till she reached a hollow or basin of some extent. Stopping at the edge, she looked carefully around, and then rapidly descending the slope, was completely hidden from the view of any one who might be passing in the distance. Reaching the bottom of the basin, which had the appearance of a huge sand-pit long since disused, she directed her course towards what was seemingly a heap of large stones piled up against the side. Stooping down, however, she discovered a space large enough to admit her, and, by bending her head, she passed through it, when she was once more able to stand erect. Stopping an instant, she produced from beneath her cloak a lantern, and, quickly lighting it, proceeded without hesitation along a passage hewn in the sandstone rock, about ten feet in height and five or six in width. Casting the light before her as she went on, she carefully noted the passages which branched off on either hand. Into one of these, after proceeding for five or six hundred yards, she entered, after minutely examining a mark on the wall--a sign to her that it was the one she sought. Still on she went, not a sound reaching her ear, till she reached what appeared to be a heap of rubbish piled up before her. Throwing the light of the lantern on one side of it, she discovered an opening similar to the one through which she had entered the subterranean labyrinth. As she advanced, the light of her lamp glancing on the walls revealed numerous slabs let into them, on which various inscriptions, with significant symbols, were rudely carved, marking them as the tombs of those who had departed in the faith of Jesus, to sleep in peace till summoned by the last trump to meet their risen Lord. Here the crown and palm-branch marked the resting-places of those who had been faithful unto death, triumphing over sin, the world, and the devil; farther on was an anchor, typifying the Christian's hope, sure and steadfast; here a ship entering harbour, to signify an entrance into the everlasting kingdom; there a dove, and an olive-branch, the everlasting peace enjoyed by those who slept within. Still more numerous were the simple and short epitaphs, some with merely the words, "In Christ;" others, "He sleeps in peace." On some were rude emblems denoting the trade or name of those buried within; on others were figures of men or women standing with outstretched hands and open palms--the universal posture of prayer.
