A couple of months ago I posted an article on HubPages called Backward Advances: Rear-Facing Trombones Throughout History. It features 29 different images from 7 different countries. Three of the most interesting examples are pre-19th century. In a similar vein, I came across this painting attributed to Luca Giordano (1634-1705), an Italian artist from the late Baroque. I’m working on finding a better reproduction, but it would appear that the brass player in the center-left could be playing a rear-facing trombone as part of a basso continuo to accompany a group of singers.
