Last April I added a Baroque still life to the timeline and mentioned it in this blog. Still life paintings that include trombone are difficult to find; most often, if they include a brass instrument, they seem to include trumpet rather than trombone. However, I recently found the below image, also from the 2nd half of the 17th century, and added it to the Trombone History Timeline (17th century, 2nd half). The trombone in this particular painting is also unusual in that it is shown facing straight on, as if pointed almost directly at the viewer.

c. 1670—Italy: Bartolomeo Bettera’s Still Life with Musical Instruments includes a trombone in the center of the image (see below image; public domain).
