All of the above, with a big thumbs up for Don Quixote - in Spanish if you possibly can.
(Minus Rand, naturally. Her reactionary politics, solipsistic philosophy and prose leave lots to be desired. Horrible reading + mind poison for NT's.)
As a suggestion from waaaaay out of the standard, you might think of two really epic series of books. The first are the books by
Mika Waltari, Sinuhe The Egyptian, or just "The Egyptian" sometimes, is romp through the cultures in and around Egypt at and around the time of Akhenaton, who is The Daddy of Monotheism. The second suggestion would be
. There's no describing the books, you'll love them or hate them, but they're a riot. Love love love. The tropics are a great place to start. Capricorn was better than Cancer for me, but you should read Cancer first.
Oh, and my enthusiasm for things Millerian made me forget the
series of books... Which are another series of sprawling, truly epic books based around the key events in the history of Central and South Americas.
(the links are working randomly... Waltari works fine, but the others... meh.
