Anyway, my young history master from a public school will be travelling from England to Italy during the Easter hols some time in the 1890s, as a chaperone for one of his younger students on his way to visit his guardian. The route from Paris will be something like Strasbourg-Basel-Zurich-St Gotthard-Milan-Firenze-Rome-Naples (unless any experts are objecting). Now, my estimation is that the journey might take something like two nights and one day - possibly even two. Does that sound realistic?
