c. 1645—Campione d’Italia, Italy

Isidoro Bianchi paints Gloria d’angeli, a fresco in the sanctuary of S. Maria dei Ghirli. The painting includes an angel playing what may be an awkwardly-rendered trombone, with a slide clearly visible but without the rear bow of the instrument extending behind the head (see detail and full image below; public domain) (Angelis 43). For a similar rendering by the same artist, see 1623, above.
