Added a really nice painting by German artist Hans Baldung to the 16th Century Timeline, dating from fairly early in the history of the trombone. The angel’s grip of the slide is interesting, but probably not a literal representation. In general terms, notice the fairly equal balance of religious versus secular trombone iconography from the 16th century.
1516—Freiburg, Germany: Hans Baldung’s painting, Coronation of the Virgin, the central panel of an altarpiece located in the Freiburg Cathedral, includes an angel-trombonist among a group of angels playing wind instruments above and to the left of the Virgin (see facing detail and full image, below; public domain) (Burkhard pl. 2).
