The rehearsal took place on Resurrection Day, April 18, as we learn from the 48th letter in the Köchel Collection, which, together with the preceding two (Nos. 46 and 47), belong in the year 1813, not in 1819, as Köchel surmised. The following little note to Zmeskall refers to the rehearsal: Meanwhile I thank you, dear Z., and inform you that the rehearsal will take place at the Archduke’s to-morrow afternoon at 3 o’clock--but I shall give you the particulars to-morrow morning--for the present I have announced it. Your Beethoven. To Zmeskall he wrote on April 23: Dear Z.: All will go well, the Archduke will take this Prince Fitzly Putzly soundly by the ears--let me know if you intend to eat at the inn to-day or when you do? Then tell me please whether “Sentivant” is correctly spelled, as I want to write to him at the same time for the chorus. I must yet consult with you about the day to be chosen, moreover you must not let anything be observed about the enlistment of the Archduke, for Prince Fitzly Putzly will not come to the Archduke till Sunday, if this wicked debtor were to observe anything in advance he would try to get out of it. (On April 26): Lobkowitz will give me the theatre for a day after May 15, it seems to me this is about as good as none at all--and I am almost of a mind to give up all thoughts of a concert. He above will surely not let me go utterly to ruin. (On May 10): I beg of you, dear Z., not to let anything be heard about what I said to you concerning Prince L., as the matter is really going forward and without this step nothing would ever have been certain. I have looked for you at the S. every day, but in vain. [Sidenote: PICTURES WITH MUSICAL ACCOMPANIMENT] There follows another long letter to Varena: My dear V! There can be no harm in notifying you in advance of what I am sending you; you may be able to use more or less of it. You will receive 3 choruses which are not long and which you can use at different intervals in the concert--a large scene for bass voice with chorus; it is from the “Ruins of Athens” and occurs where the picture of our Emperor appears in view (in Ofen, Hungary, this came upon the stage from below). You may be able to use something of the kind to--stimulate the multitude.
