I recently added the second image below to the Trombone History Timeline (16th Century). It’s by Pieter de Witte (c. 1548-1628), also known as Peitro Candido and Peter Candid. He was probably born in the Low Countries, grew up and trained in Italy, then spent his career in Italy and Germany. He seemed to have an affinity for depicting trombone players in his art work. The other two images shown below are also by the same artist. The dates for the three art works, from top to bottom, are c. 1575, 1593, and 1611.
