Tetanus is caused by the tetanus bacterium Clostridium tetani. Tetanus is often associated with rust, especially rusty nails. Objects that accumulate rust are often found outdoors, or in places that harbour anaerobic bacteria, but the rust itself does not cause tetanus nor does it contain more C. tetani bacteria.
Nikos Kazantzakis: Saviours of God. Kazantzakis and his Wisdom Literature: Nikos Kazantzakis (1883-1957), the great poet-philosopher of modern Greece, authored over 30 books. He was nominated several times for the Nobel Prize, and in 1957 lost by only one vote.
Its a difficult mix. I came away from Kazantzakiss book feeling that he was unfair to Francis, turning him into a very fine 20th century Existentialist character, and not presenting him as a 13th century mystic, aesthetic and saint. It is not that Kazantzakis would deny him these traits, in fact he celebrates them.
