We visited, one day, the catacombs of St. Calixtus with a party of friends, among whom was the then celebrated Padre Machi, an ecclesiastic who was considered a supreme authority in this department of historic research. Acting as our guide, he pointed out to us the burial-places of martyrs, distinguished by the outline of a palm rudely impressed on the tufa out of which the various graves have been hollowed. We explored with him the little chapels which bear witness to the ancient holding of religious services in this dark underground city of the dead. In these chapels the pictured emblem of the fish is often met with. Scholars do not need to be reminded that the Greek word [Greek: ichthus] was adopted by the early Christians as an anagram of the name and title of their leader. Each of us carried a lighted taper, and we were careful to keep well together, mindful of the danger of losing ourselves in the depths of these vast caverns. A story was told us of a party which was thus lost, and could never be found again, although a band of music was sent after them in the hope of bringing them into safety. While we were giving heed to the instructive discourse of Padre Machi, a mischievous youth of the company came near to me and said in a low voice, "Has it occurred to you that if our guide should suddenly die here of apoplexy, we should never be able to find our way out?" This thought was dreadful indeed, and I confess that I was very thankful when at last we emerged from the depths into the blessed daylight. Among the wonderful sights of that winter, I recall an evening visit to the sculpture gallery of the Vatican, where the statues were shown us by torchlight. I had not as yet made acquaintance with those marble shapes, which were rendered so lifelike by the artful illumination that when I saw them afterward in the daylight, it seemed to me that they had died. My husband visited one day the Castle of St. Angelo, which was then not only a fortress but also a prison for political offenders. As he passed through one of the corridors, a young man from an inner room or cell rushed out and addressed him, apparently in great distress of mind. He cried, "For the love of God, sir, try to help me! I was taken from my home a fortnight since, I know not why, and was brought here, where I am detained, utterly ignorant of the grounds of my arrest and imprisonment." This incident disturbed my husband very much. Of course, he could do nothing to aid the unfortunate man.
