The war loot taken from Dresden in 1745-46 was split between the different institutions in the former Soviet Union. So the music removed from the SLUB, including the missing vesper psalms listed above, likely ended up in the music collections of city and university libraries all over the country. For example, the Russian State Library in Moscow holds what seems to be items from Zelenka’s collection with the letters A (Aldrovandini, Allegri, Ariosti etc.), and other materials as well. These can now be viewed in the online-catalogue of the library.
This library also holds a large chunk of the missing libretto collection of the SLUB, which always was thought to have perished in 1945. This is of importance for Zelenka research as well, because he would have prepared many of the little labels affixed to these, as a part of his cataloguing and custodianship of the royal music library in Dresden. Moreover, a lot of these librettos are manuscript copies and likely in the hand of the Dresden court poets (Pallavicini etc.), and hold vital information for the authorship of texts of missing works, names of performers, and possibly comments of August III or Maria Josepha on the contents – as we have seen in the few existing Dresden librettos in the SLUB and in the Berlin State Library. This is a major study for which I have already done much work by partly reconstructing the long lost catalogues assembled by Zelenka, but one that can only be finalised with a visit to Moscow.
The Glinka Museum in Moscow also holds items from the SLUB. In preparation for my article on the secular vocal collection of Zelenka I asked the music director and conductor Nikolay Khondzinsky, who we know for his spirited performances of Zelenka, to visit the museum to look at a volume of cantatas which I suspected to include music from Zelenka’s collection. In spite of several attempts he found it was practically impossible to get access, and this is the problem in a nutshell. The war loot is still a delicate issue in Russia and it is likely that the parts from the Zelenka collection are still kept under lock and key in the largest cities in the country, and in the former territories of the Soviet Union. Unfortunately, the window of opportunity that was open for a short period during the rule of Boris Yeltsin, and allowed for the return of the Sing-Akademie collection from Ukraine, was firmly shut when Putin took office.
The cataloguing of the Sing-Akademie collection is long finished and by now well documented in several publications. And our Zelenka was well presented, as I reported on here in 2007. It has proved to be a near bottomless treasure trove, which still is revealing its secrets through the many anonymous works, as I have found out during my ongoing study of Johann Joseph Adam, prince of Liechtenstein and patron of Vivaldi.
When it comes to the missing works of Zelenka, the situation is this as I see it: we desperately need a very, very wealthy patron burning with passion for the composer, who would be willing to donate large amounts of money to fund a long-standing systematic search in Russian libraries and archives. Anyone, please:)?
