So it was on the morning of Tuesday, the 16th of December, 1631. Yet fair as was the scene on which the sun rose that day, it was to be greatly changed ere night. Early in the morning, the citizens were startled and somewhat alarmed by a very perceptible tremulousness of the earth under their feet. It increased in violence as the hours rolled on, and the atmosphere too, December though it was, became sultry and close. The inhabitants of the beautiful villas and the farmers and country laborers, who had felt the trembling of the earth and the closeness of the atmosphere more sensibly than the citizens, and who saw at once that it was caused by the mountain, commenced to flee with their families for safety into the city. About 9 A.M. a cry of affright went up from the city and the country, as suddenly the mountain shook and roared as if in agony. All eyes turned to the summit of Vesuvius, only yesterday so fair and green. A huge turbid column of smoke was seen swiftly springing upward from its cone toward the sky. High up, it spread out like the top of a mighty pine or palm. The lightning flashed through this rolling, surging, ever-increasing mass as it rapidly expanded on every side. By 11 A.M., Naples lay under the dark and fearful cloud which shut out the heavens and darkened the day. The incessant trembling of the earth was perceptibly increasing in violence. Men felt that they were at the beginning of they knew not what terrible tragedy, before which they felt themselves utterly powerless. The ever-open churches were soon crowded with fear-stricken suppliants. The cardinal archbishop at once directed religious services to be commenced in them all, and to be continued without intermission. In the hours of the afternoon there would be a procession through the streets near the cathedral, in which the relics of St. Januarius would be borne. Men prayed to be spared from the impending doom. The trembling earth might open to swallow them; the tottering houses might fall and crush them; or the mountain, whose sullen roar, like that of an angry monster, they heard amid and above all other sounds, might destroy them in some other more fearful way. They prayed and did penance, like the Ninivites of old. They sought to prepare their souls for the death which might come to many of them. 37
