I just added the below images and caption to the Trombone History Timeline (17th century, 1601-1625) and to the collection, Angel Trombonists throughout History (where there are now 115 examples).

Early 17th century—Fiegni, Fiastra, Italy: Incoronazione della Vergine, a fresco in the apse of the Sanctuary of the Blessed Ugolino, or Beato Ugolino sanctuary church, includes an angel playing trombone (see detail and full image below; public domain).
