On some tracing boards, you see Hiram laying in his grave. The above is a Strikte Observanz tracing board from around 1770. It seems that SO derived systems, such as the Rectified Scottish Rite also use this tracing board.
Hiram as a character plays a big role in “craft” degrees, the “Ancient and Accepted Scottish Rite” and other Masonic systems.
Note the animals in the corners. A lion, a monkey, a fox and a dove.
