Other cantatas of this period were written for special occasions such as the 200th anniversary of the Augsburg Confession in June 1730, funerals and weddings. Obviously some of the information and compositions of this period of writing and performing of cantatas are missing, leading to different ways of presenting and connecting what is known about them by Bach-scholars. For instance, in the 19th century Spitta considered almost all of Bach's chorale cantatas as late cantatas,Philipp Spitta, translated by Clara Bell and J.A. Fuller Maitland. Book V: The Final Period of Bach's Life and Work, ChapterIII: "The later Chorale Cantatas" pp. 64–108 in Johann Sebastian Bach: His Work and Influence on the Music of Germany, 1685–1750 Volume 3. Novello & Co. 1884–1885. while later research connected the large majority of them to the composer's second year in Leipzig (1724–25). "Introduction", pp. 29–45
