Today I added the below caption and image to the Trombone History Timeline (16th century).

c. 1525—Basel, Switzerland: A woodcut by Hans Holbein the Younger depicts David’s Song of Thanksgiving, 1 Chronicles 16, with Asaph and his musical ensemble ministering before the Ark of the Covenant (Asaph was head of music for King David). The print belongs to a series of 91 woodcuts depicting Old Testament scenes. The brass player in the back-right, closest to the ark of the covenant, appears to be playing a trombone. The instrument’s slide extends past the bell and back bow of tubing extends past the shoulder. Also, the player’s grip is not fixing the instrument against the mouth in the manner of a slide trumpet, like the other players in the foreground (see detail and full image below; public domain).
