I had the great good fortune to form a cordial friendship with Jakob Burkhardt, an unusual thing with that very hermit-like and secluded thinker. A still greater piece of good fortune was that from the earliest days of my Basle existence an indescribably close intimacy sprang up between me and Richard and Cosima Wagner, who were then living on their estate of Triebschen, near Lucerne, as though on an island, and were cut off from all former ties. For some years we had everything, great and small, in common, a confidence without bounds. (You will find printed in Volume VII of Wagner's complete works a "message" to me, referring to _The Birth of Tragedy_.) As a result of these relations I came to know a large circle of persons (and "personesses"), in fact pretty nearly everything that grows between Paris and Petersburg. By about 1876 my health became worse. I then spent a winter at Sorrento, with my old friend, Baroness Meysenbug (_Memoirs of an Idealist_) and the sympathetic Dr. Rée. There was no improvement. I suffered from an extremely painful and persistent headache, which exhausted all my strength. This went on for a number of years, till it reached such a climax of habitual suffering, that at that time I had 200 days of torment in the year. The trouble must have been due entirely to local causes, there is no neuropathic basis for it of any sort. I have never had a symptom of mental disturbance; not even of fever, nor of fainting. My pulse was at that time as slow as that of the first Napoleon (= 60). My speciality was to endure extreme pain, _cru, vert_, with perfect clarity, for two or three consecutive days, accompanied by constant vomiting of bile. The report has been put about that I was in a madhouse (and indeed that I died there). Nothing is further from the truth. As a matter of fact my intellect only came to maturity during that terrible time: witness the _Dawn of Day_, which I wrote in 1881 during a winter of incredible suffering at Genoa, away from doctors, friends or relations. This book serves me as a sort of "dynamometer": I composed it with a minimum of strength and health. From 1882 on I went forward again, very slowly, it is true: the crisis was past (my father died very young, just at the age at which I was myself so near to death). I have to use extreme care even to-day; certain conditions of a climatic and meteorological order are indispensable to me. It is not from choice but from necessity that I spend the summer in the Upper Engadine and the winter at Nice.... After all, my illness has been of the greatest use to me: it has released me, it has restored to me the courage to be myself.... And, indeed, in virtue of my instincts, I am a brave animal, a military one even. The long resistance has somewhat exasperated my pride. Am I a philosopher, do you ask?--But what does that matter!... 11. BRANDES to NIETZSCHE. _Copenhagen_, April 29, 1888. MY DEAR SIR,
