My dear Liszt,
You will know by this time how I have fared in Paris. The performance of my overture came to nothing, and all your trouble about it has been in vain. Poor man! In my life some decisive events have happened; the last shackles have fallen that tied me to a world in which I must have perished soon, not only mentally, but physically. Through the eternal compulsion imposed upon me by my immediate surroundings, I have lost my health, and my nerves are shattered. In the immediate future I must live only for my recovery; my existence is provided for; you shall hear from me from time to time. Dear friend, I have just been looking through the score of my Lohengrin. I very seldom read my own works. An immense desire has sprung up in me to have this work performed. I address this wish to your heart: Perform my Lohengrin! You are the only one to whom I could address this prayer; to none but you should I entrust the creation of this opera; to you I give it with perfect and joyous confidence. Perform it where you like, even if only in Weimar; I feel certain you will procure every possible and necessary means, and they will refuse you nothing. Perform Lohengrin, and let its existence be your work.
There is a correct score of the opera at Dresden. Herr von Luttichau has bought it of me for the price of the copying, thirty-six thalers. As he is not going to perform it, against which I should protest, considering the musical direction in that city, it is possible that he will let you have the copy on repayment of the thirty-six thalers, or else he will in any case have it copied out for you. This letter may be your authority for receiving it. If you comply with my wish, I shall send you soon a complete libretto, with exact indications of my view as to the mise-en-scène, etc. Do what you can and what you like. You shall soon hear from me again. Belloni tells me that you have promised him to get me an additional five hundred francs for the score of Iphigenia. If you succeed in this, remit the money for me to Belloni; I shall in my thoughts dispose of it.
