Euterpe, Greek Muse of Music, Playing with a Trombonist?

Last week I posted on an image by Peter de Witte (Peter Candid) that can be found on an impressive array of media: canvas, paper, silver, and glass. While I was researching that image, I found another by the same artist that includes a trombone. It features Euterpe, Greek muse of music. At her feet, putti play trombone, flute, and cornetto, and a shawm rests nearby. The drawing has been added to the 17th century timeline.

1611—Pieter de Witte (also known as Peter Candid) includes an angel playing trombone in his drawing, Euterpe (see bottom-left of below image) (Volk-Knüttel 102).
