Vaslav Nijinsky was probably the greatest dancer of all time - the God of the Dance - and his diary must have been one of the most extraordinary and moving books ever written.
It was written in 1918-19 in St Moritz, where Nijinsky had retired, suffering extreme mental agony, in an attempt to escape the shadow of Diaghilev - the man who made him as a dancer, and broke him as a coherent personality. It is amazing that, grappling with insanity, Nijinsky was able to communicate his feelings so lucidly. Like van Gogh's letters, his diary is a rare and precious document.
