From a French tracing board from the early 1700’s. Les Franc Macons Ecrasé calls this a “joug” which indeed means “yoke”.
Fedderson F/16
On what Feddersen describes as a “plan of the lodge in the Scottish degree” (from France) we see a dove in the East, a pelican in the North, a lion in the middle, an ape in the South and a fox in the west. He also says that the fox should be accompanied by a drum, the monkey with a yoke, the lion with crossed swords and the pelican with scales. That does not quite explain if the lion/crossed swords refers to a function or an element in the ritual.
