I've made an attempt at mapping Twain's route through Italy in the Spring of 1892. This follows departing the French Riviera at Menton; to Pisa, Rome, Florence, Venice, and finally at Cadenabbia on Lake Como. I have little to no detailed information on the specifics of the routes taken and have relied on an 1896 map of European railways - along with Google Earth's railroads overlay. https://twainsgeography.com/content/italy-spring-1892 My map of routes is interactive, meaning it can be viewed in full screen and enlarged to a precise level. If anyone has specific knowledge of exactly where they were in this time-frame it would be helpful, allowing me to fine tune the map. I assume this would mean anyone with access to letters posted by Twain's daughters and/or Livy. I'm thinking of the invaluable assistance provided by Miki Pfeffer and the note on St Gothard/Gotthard Pass. Thanks...
