The Masonic Lodge Floor Explained
Note that the horizontal (latitude) lines at 23.5 degrees are called the tropics and they represent the north and south limits of the sun's apparent daily position when watched over a year's time. The pair of vertical lines indicate the limits of the 47 (2 x 23.5) degree nutation circle of the earth's axis. This is the Master's Square on the center.
Here (above) we see two hemispheres of the earth being depicted. The two circles touching are, of course, the hemispheres. The outer circles are the circle of the heavens in two hemispheres. Note especially how the overlap of the outer circles matches the width of the square determined by the lines of the tropics.
This is Bromwell's version of the earth bordered by the celestial sphere with all the astromical lines portrayed, including the apparent path of the sun as seen from the earth. But the ritual not only includes how it looks as seen from the earth, but how it looks from three different perspectives. Let me show you...
Remember that since the sun never gets above 24 degrees on the earth, people north of there always look to the south to see the sun at noon; while people over 24 degrees south of the equator always have to look north for the sun at noon. At the equator the sun is north half the time and south half the time.
The first degree coresponds to the northern view, the second degree to the southern view, and the master's degree to the middle view. The first degree also pertains to the June Soltice, the sun's most northerly point, the northeast, and the left, as that is where the NE Is looking east into the sunrise. The second degree pertains to the December Soltice, the southeast and the right. The master's degree pertains to the equator and the equinoxes.
At the equinox at the equator there are 12 hours of light and 12 hours of darkness. We find that the symbolic floor of the Master's Degree is composed of 25 stones; 24 around a cubic foundation stone. The master's floor represents the square generated by the tropics in the top image. Bromwell suggests that this is the configuration of the stones on the breastplate of the Hebrew priest, as well as the layout of the Hebrew camp in the desert.
Below we see a circular version of this idea portrayed on a wall in the position of a rose window of a cathedral. It's Arthur's Round Table, featuring 24 alternating black and white spaces around a center circle. Note the emblem of the sun at the top. Its hard to tell how many concentric circles are being depicted.
