January 21, 1786: Carl Philipp Emanuel Bach (71) writes to Johann Joachim Eschenburg about Charles Burney’s Handel (†26) Commemoration, which Eschenburg sent to him. He disagrees with many assertions by Burney and finds Handel wanting in comparison to Johann Adolf Hasse (†2), Carl Heinrich Graun (†26), Reihard Keiser (†46) and his father, Johann Sebastian Bach (†36). He also reports to Eschenburg that “I recently burned a ream and more of old works of mine and am glad that they are no more.” (Wolff, CPE Bach, 214)
