I've been working on a slideshow for chapter 19 from The Innocents Abroad. The chapter contains some interesting observations on art critics and their perceptions, particularly in regards to The Last Supper. There is, however, another observation made by Twain, a single paragraph describing an unattributed painting. I was wondering if anyone can identify the painting and artist and if an image of the painting exists on-line anywhere. The paragraph reads: "In another place we were shown a sort of summer arbor, with a fence before it. We said that was nothing. We looked again, and saw, through the arbor, an endless stretch of garden, and shrubbery, and grassy lawn. We were perfectly willing to go in there and rest, but it could not be done. It was only another delusion—a painting by some ingenious artist with little charity in his heart for tired folk. The deception was perfect. No one could have imagined the park was not real. We even thought we smelled the flowers at first."
