Most excellent,
                   Most gracious Prince!
                      As 
                I am told that you, my Prince, have been asking about the Mass 
                which you commissioned me to compose for you, I am taking the 
                liberty of informing you, most excellent Prince, that you will 
                receive it by August 20th at latest -- That will give us sufficient 
                time to produce it on the name-day of the most excellent Princess 
                -- Extraordinarily advantageous conditions which were offered 
                to me from London at a time when I had the misfortune to 
                fail to obtain a benefit day in the theatre and which necessity 
                compelled me gladly too except, have delayed the completion of 
                the Mass, however much I desired it to deliver it in person to 
                you, most excellent Prince. In addition, I was afflicted somewhat 
                later by an illness which affected my head. This prevented me 
                at first from working at all and later and even now has allowed 
                me to do very little work. Since people are so ready to construe 
                everything to my disadvantage, I am in closing, my most excellent 
                Prince, one of my doctor's letters -- May I am did that I show 
                hand you the Mass with considerable apprehension, since you, most 
                excellent Prince, are accustomed to have the inimitable masterpieces 
                of the great Haydn performed for you --
                      Most 
                excellent, most gracious Prince! -- with deepest respect you're 
                most devoted, you're most humble 
                                                                                 Ludwig 
                von Beethoven
