I added the below caption and images to the Trombone History Timeline (16th century). Kind of interesting how many images there are from Verona of trombonists playing from balconies!

1598-1602—Verona, Italy: A painting by Felice Riccio (aka Felice Brusasorzi), on the inner organ shutter (right side), left organ, in the Cathedrale Santa Maria Matricolare, includes a trombonist (see detail and full image below; public domain).
