This arrangement of “three squares, on top of which are three circles, on top of which are three triangles” can be seen on the tracing boards for the degrees ‘Knight of the East or Sovereign Prince of the Rose Cross’ and ‘Knight of the Eagle or Sovereign Prince of the Rose Cross’, both displayed in volume III of Maçonnerie des Hommes.
In the Mirecourt collection of degrees, the arrangement is described in the 21th degree ‘Knight of the Rose Cross’ as representing calvary hill, Golgotha.
