Thanks - will look out for both.
Thank you for the info.
In terms of Pompeii, Pliny the younger did watch and write about the eruption that destroyed Pompeii so they might be referring to that. Although he did it from a fair distance and wrote it 20+ years later. That said a lot of his account backs up the archaeological evidence.
I would add heat but it's already been added to Pompeii. ;) I'll look forward this, I've visited Pompeii and love it.
