An exploration of the art in Milan, Di Vinci, Michelangelo, etc. We also get a peek at Lucretia Borgia and Petrarch's Laura. The chapter contains Twain's reflections on Di Vinci's The Last Supper and comments on how the image is described by viewers. How is it possible to perceive the many nuances said to be found in the painting when it is in such a degraded condition. The Last Supper was described by Twain in Letter number 8 to The Daily Alta California. This is only a small portion of the letter. I expect to include a copy of the letter with the Chapter 20 material. This is another slide show created with the open source program, Imagination. I often become dissatisfied with the vocal track of these shows because of misplaced words and phrases and moments where timing could be improved. But then, these are unrehearsed and essentially unedited live performance recordings. I do cut out unnecessary breaks in the dialogue caused by interruptions and filter on-line noise but otherwise they are straight readings.
