With the new disaster movie Pompeii premiering this weekend, National Geographic is presenting this new documentary, which visits the actual Italian site of history’s most famous volcanic disaster. I’ve toured Pompeii, and seen these frozen-in-the-moment body casts for myself. (I’ve also stared lengthily at the surviving painted-on-the-walls “menus” at the local Pompeii whorehouses, which listed available services in such matter-of-fact detail, it was like reading a dollar menu at McDonald’s. I’d have stayed even longer to read and memorize the list, but I didn’t want to make an ash of myself.)
