Added the first image below to the Trombone History Timeline (17th century, 1601-1625). The Sadeler engraving that I reference in the caption is shown below it.
c. 1615—Hans Rottenhammer’s painting, Madonna col Bambino in Gloria con angeli musicanti, bears several similarities to Raphael Sadeler’s engraving, Allegory of the Immaculate Conception (which, in turn, is after a painting by Pietro Candido). An angel playing trombone is featured on the bottom-left of the image (see below image; public domain).
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).
