I just added the below caption and image to the Trombone History Timeline, 17th century (1601-25). I also added it to the collection, Angel Trombonists Throughout History: 119 Images.

c. 1620-24—Wolfenbüttel, Germany: The organ is installed at the Wolfenbüttel Hauptkirche. Paintings located under the organ balcony, which probably date from the same period, include an angel playing trombone (see below image; public domain).
