1682—Salzburg, Austria

A copperplate engraving by Melchior Küsel, Musical Festival in the Salzburg Dome, 1682, depicts an antiphonal performance in the Salzburg Cathedral for one of the festivities of the Jubeljahr. Pictured in one of the choirs in one of the four balconies are what may be two trombones (see below image; public domain) (Salzburg, Museum Carolino Augusteum) (Chafe 44; Naylor 40).
