c. 1550—Verona, Italy
A painting of angel musicians by Domenico Brusasorzi (also called Domenico Brusasorci and Domenico Riccio) in the Chiesa di Santa Maria in Organo includes what is probably a trombone. Although the bell section is longer than the slide, the slide is still quite long and is gripped like a slide of the time; also, the rear bow of tubing extends behind the player’s shoulder (see below image; public domain) (Paganuzzi, La Musica a Verona, fig. 307).
