Il Gattopardo. A wonderful novel which will help you understand Sicily when you visit (which you should - it's not the same old Italy - it's not really Italy at all). Wonderful place, insanely governed (like most places) but the people seem to ignore the government. They have been ignoring governments for thousands of years, despite constant invasions by everybody - including the Vikings.
‘The Leopard’ Turns 50
The movie starred Burt Lancaster. I haven't seen the movie.
By coincidence, I have just finished a birthday book, Di Lampedusa's novella, The Professor and the Siren. It reads like poetry.
