Nearly 2,000 years ago, Pompeii was buried under the volcanic ask from the Vesuvius. It was estimated that ~2,000 people died, mostly the elderly and the slaves - those who would not or could not leave, despite the signs of a an imminent eruption.
Some moulds of the victims were made. Many are being exhibited in museums, in Pompeii and elsewhere around the world. A few are left on the site. That included a boy,
and a dog.
The dog, in particular, seems to be still in agony.
