The second section of vertical patterns represents the three degrees of Freemasonry. The Entered Apprentice Degree is found at each vertical edge in the single checkered dark blue patterns and white accent lines. The Fellowcraft Degree is represented by the lighter pair of checkered blue patterns containing the vertical set of light blue & black lines. The Master Mason Degree is represented by the three central checkered blue patterns containing the two vertical light blue lines.
The third section of horizontal patterns represents existence as described throughout the Masonic lectures, expressed by the hermetic phrase “as above, so below.” The trinity of Faith, Hope, & Charity, the stages of life, the Masonic funeral rites, and the allegory of Jacob’s Ladder each address these divisions. The pattern reflects across itself from the world above, to the Earthly plain, to the world below.
