Professor, Nikos Kazantzakis is one of the greatest Greek writers ever born. Most people know him through his novel "Zorba" (movie version, "Zorba the Greek" with Anthony Quinn) but "Christ Recrucified" is one of his best. (Small confession: I liked "Zorba" even better than "Christ Recrucified," because it didn't really deal with religious issues, only with the character of man, in this case, classical Hellenic (non-religious) man, but they are both excellent works.)
I really hope you enjoy it.
