Dear friend!
I have never read anything more beautiful than your book! It is simply glorious! I am writing you in great haste, as my excitement is so great at the moment that I must await the return of reason before being able to read it carefully. I have just said to Cosima that you stand second only to her; then, for a long time, there is no one until we reach Lenbach, who has painted such a striking portrait of me! Consider well what she has written, but cultivate indifference as far as the rest of the world is concerned!
Adieu. Run over at the first opportunity and we shall have a veritable Dionysian feast!
