I added this image and caption to the Trombone History Timeline (17th century—first half). I also added it to the collection of angel trombonists and collection of images showing the grip of the early trombone.

c. 1620—Imola, Italy: Visione di S. Cecilia e angeli, a painting by Giovanni Battista Bertusio (1577-1644) located in chiesa di S. Agata, includes a depiction of an angel playing trombone (see detail and full image below; public domain) (Negro and Roio 37).
