Pompeii is one of those places on earth that has ghosts. You feel the past lingering on in so many ways. It's more than knowing that Vesuvius erupted in Aug of 79AD. Partially it's knowing that the city was encased in ash and somewhat preserved. Some of the feeling comes from seeing the casts of the people who were frozen in their deaths in ash. I think it's more, though, a sense of space and time that cross in some way to encourage a mystical feeling in the visitor. I would love to return to Pompeii.
This poor man was frozen in the ash, then cast. He is now encased in glass in a courtyard along with another figure.
