We remained somewhat too long in Rome that spring and what with the effect of the increasing heat and the discouraging circumstances already described my brother resolved not to write any more or in any case not to proceed with "Zarathustra" although I offered to relieve him of all trouble in connection with the proofs and the publisher. When however we returned to Switzerland towards the end of June and he found himself once more in the familiar and exhilarating air of the mountains all his joyous creative powers revived and in a note to me announcing the dispatch of some manuscript he wrote as follows: "I have engaged a place here for three months: forsooth I am the greatest fool to allow my courage to be sapped from me by the climate of Italy. Now and again I am troubled by the thought: WHAT NEXT? My 'future' is the darkest thing in the world to me but as there still remains a great deal for me to do I suppose I ought rather to think of doing this than of my future and leave the rest to THEE and the gods."
