There's a notion that the Neanderthals were finally knocked on the head by the Campanian Ignimbrite eruption 39000 years ago. The source of that super-eruption was what is now the Campi Flegrei caldera, the Fiery Fields, just west of Naples (not Vesuvius, which is on the other side). Don't bank on it never going off on one again. San Gennaro, the patron saint of Napoli, was beheaded in the Solfatara crater there in the fourth century. His bones are gruesomely displayed in an urn in Naples Cathedral. I have it on good authority that Putin was responsible. I got the worst mosquito bite I've ever had in my life in La Solfatara in September 2013. Still got the scar on me leg. But I'd go again any day. The Bay of Naples to me is the alpha and omega, the beginning and end of everything that matters.
