 In 1709 he was appointed cantor at Altstadt Church, one of Königsberg’s three key musical positions, which he occupied until his death.Riedel's unique monumental settings of the entire Gospel of Matthew, the entire Book of Psalms, and the entire Book of Revelation, were preserved in the Königsberg Public Library.His compositions are probably lost due to the destruction of Königsberg in 1944 and 1945 during World War II.
