[83] In his letter to Zelter, Beethoven says that one of the numbers of the Mass was without accompaniment. There being no _a cappella_ setting of any section of the missal text in the Mass in D, it is likely that Beethoven here, too, had the three additional pieces in mind. For this speculation, however, as well as the hypothesis that the settings originally contemplated for the “second” mass in C-sharp minor were transferred to the scheme of the _Missa Solemnis_, the present editor is alone responsible. In a Conversation Book of 1823 an unidentified friend answers several questions about the hymn “Tantum ergo” and its introduction in the service. [84] Schindler bases his statements on alleged testimony of the Archduke’s secretary Baumeister, but there is no word of reproval in any of the letters of the two men which have been found. [85] Sporchil’s drama bore the title “The Apotheosis in the Temple of Jupiter Ammon.” What it had to do with the new operatic project is not plain to this editor, for it was but a new text to be used to the music of “The Ruins of Athens.” Beethoven once described “The Ruins” as “a little opera” and his abiding and continued interest in it is disclosed by the fact that after he got into touch with Grillparzer he discussed the possibility of its revival with that poet. [86] Grillparzer’s “Werke,” Vol. XVI, p. 228 _et seq._ [87] Thayer saw Grillparzer on July 4, 1860, and got from him a confirmation of both incidents here narrated. [88] The concluding paragraph of the letter betrays his growing antipathy towards Schindler: “Afternoons you will find me in the coffee-house opposite the ‘Goldene Birne.’ If you want to come, please come alone. This importunate appendix of a Schindler, as you must have noticed in Hetzendorf, has long been extremely objectionable to me--_otium est citium_.” [89] Thayer copies the entry found in the Conversation Book, but doubts if the handwriting is that of Liszt _fils_. It is as follows: “I have often expressed the wish to Herr von Schindler to make your high acquaintance and am rejoiced to be able now to do so. As I shall give a concert on Sunday the 13th I most humbly beg you to give me your high presence.” The courtly language suggests the thought that the father may have written the words for the boy.
