Historical books

Currently reading this Mark Twain book. Written in 1867 and is basically a travelogue. He
is in Venice now and talks about being in "a half waking sort of dream" He says
he cant explain the feeling but part of him remained in the 19th century wile also
walking among phantoms of the 10th. Having been there twice I really identify with that .
This is another example of  really connecting with an author an why I love reading historical books
