I added the below image and caption to the Trombone History Timeline (1626-1650). I also added it to both the collection of angel trombonists and the collection of images demonstrating the grip of the early trombone.
Although this painting was created a generation before J.S. Bach was born, the location is quite close to where the composer grew up in Lower Saxony and Thuringia.
c. 1640—Goslar, Germany: A painting at the church of St. Jakobi includes an angel playing trombone (see below image; public domain).
