I just added the below entry and pictures to the Trombone History Timeline (17th century—first half). It is an engraving after an image by Peter Candid (also known as Peter de Witte and Pietro Candido). For more trombone images by Candid, see here. As you can see, it features yet another angel trombonist; for many more pictures of angels playing trombone, see Angel Trombonists Throughout History.

1615—Munich, Germany (?): Allegory of the Immaculate Conception, an engraving by Raphael Sadeler (1584-1632) after Peter Candid (also known as Peter de Witte and Pietro Candido), includes an angel trombonist among a group of musical angels (see detail and full image below image;  public domain).
