"We came out from under the solemn mysteries of this city of the Venerable Past - this city which perished, with all its old ways and its quaint old fashions about it, remote centuries ago, when the Disciples were preaching the new religion, which is as old as the hills to us now - and went dreaming among the trees that grow over acres and acres of still buried streets and squares, till a shrill whistle and the cry of "All Aboard - last train for Naples!" woke me up and reminded me that I belonged in the nineteenth century, and was not a dusty mummy, caked with ashes and cinders, eighteen hundred years old. The transition was startling. The idea of a railroad train actually running to old dead Pompeii, and whistling irreverently, and calling for passengers in the most bustling and business-like way, was as strange a thing as one could imagine, and as unpoetical and disagreeable as it was strange."
Mark Twain, The Innocents Abroad, 1869
The above quote was in a Munich, Germany museum. We visited Munich back in December for Christmas Market-palooza. One of the museums as well as the popular tourist site, The Residenz, had tons of artwork, paintings, etc. from Naples. One of the museums was even featuring an exhibit on the Campania region with photographs taken by George Sommer in the late 1800s. And we had fun finding photos in Munich that were taken from the area right by our house.
I have not read The Innocents Abroad, but it is on my Kindle. Now let's just hope I get to it before we leave Italy (not likely, but one can dream).
