Mass), a Lutheran Mass consisting of Kyrie and Gloria, in German, set for four-part choir, strings and basso continuo. Extant instrumental works include four concerti grossi, many sinfonias, and a concerto for oboe d'amore. He also wrote for organ and harpsichord. His five operas, Diomedes (1718), Narcissus, Valeria, Artemisia, and Orion, have not survived. Stölzel is reputed to have composed over 18 orchestral suites alone (none survive), as well as 90 serenatas (vocal pieces performed as "table music"). Half of Stölzel's output, never engraved, is lost. Out of what had to have been thousands of compositions in Gotha, only twelve manuscripts survive there today. The archive at Schloss Sondershausen retains many of his manuscripts, found in a box behind the organ in 1870. Reception Stölzel enjoyed an outstanding reputation in his lifetime. Shortly after his death some of his compositions were still performed, and Friedrich Wilhelm Marpurg rated him slightly above Bach in his list of prominent composers of the 18th century. By the 19th century he was largely forgotten. From the second half of the 20th century there was an increase of musicological research about the composer, and recordings of his work. Contemporaries Before he settled in Gotha for the last thirty years of his life Stölzel had already seen his music performed from Germany to Italy. His operas had been staged in several major cities in the 1710s. His sacred music was performed from Catholic Prague to the Protestant German principalities. Even after his music production became concentrated on Gotha and Sondershausen, his music was still performed outside these places. One of his operas was performed in Altenburg in 1722, the Saitenspiel cantata cycle was performed under Johann Friedrich Fasch in Zerbst in 1724–25, and the first Passion he had composed for Gotha, and reworked around 1730, was taken up in several German cities: Johann Sebastian Bach performed Ein Lämmlein geht und trägt die Schuld on Good Friday in Leipzig. In 1736 the Passion was performed as Geistliche Und Heilige Betrachtungen der Gläubigen Seele über Ihren Leidenden und Sterbenden Jesum in Rudolstadt, and in a similar version (Der Glaubigen Seele geistliche Betrachtungen Ihres leidenden Jesu) in Nürnberg. Bach didn't only perform the work: around 1742–43 he reworked the aria "Dein Kreuz, o Bräutgam meiner Seelen" from Die leidende und am Kreuz sterbende Liebe Jesu into Bekennen will ich seinen Namen, BWV 200. The music of this work had
