Johann Wendelin Glaser was born in 1731 in Ostheim vor der Rhön, Bavaria. In 1751 he became music director in Wertheim, a position he held until his death in 1783. The 300 cantatas by this exceptionally productive composer were long unknown, and were only rediscovered by chance in 1910. The Christmas cantata "Daran ist erschienen die Liebe Gottes" comprises five movements, beginning with an opening chorus, followed by alternate arias and recitatives. A simple four-part chorale concludes the work. The cantata is easy-to-perform for choral singers and also because of its small instrumental scoring for just two flutes (or other melody instruments) and basso continuo.
