On this day in A.D. 79, Mount Vesuvius erupted. The ashes from the volcanic eruption came down on the cities of Pompei, Herculaneum and Stabiae. Thousands of people and animals died when they were covered with the ash from the eruption.
When modern researchers found empty caverns where bodies had decayed they filled them with plaster. In doing so they actually captured the dying moment of the person or animal. The photo below show one person in that final moment.
This, and the other bodies seeking relief from the horrible death, remind me of the statements of Scripture that tell about men and women who are unprepared for the judgment of God.
Then they will begin to say to the mountains, Fall on us! and to the hills, Cover (conceal, hide) us! (Luke 23:30)
Then the kings of the earth and the great ones and the generals and the rich and the powerful, and everyone, slave and free, hid themselves in the caves and among the rocks of the mountains, calling to the mountains and rocks, “Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb, for the great day of their wrath has come, and who can stand?” (Revelation 6:15-17)
Pliny the Younger, whose uncle (Pliny the Elder) died in the event, left an account of the terror of the day.
