What is referred to as sacred grometry?

The Craft sources do not explicitly use the phrase "sacred geometry," but they treat the science of geometry itself as having a divine, moral, and symbolic nature 34. In the Old Constitutions and early Masonic manuscripts, geometry was treated as synonymous with Masonry and regarded as the foundation of all the liberal arts and sciences 124.

Within Craft Masonry—specifically in the Fellowcraft degree—geometry moves beyond practical mathematics or Euclidean problems to serve as a symbol 35. Carl H. Claudy explains that geometry functions as a symbol of universal law, order, and Deity, representing man's recognition of God as the "Great Geometer" who structured the universe by immutable laws 3. William Preston similarly notes that geometry is of a divine and moral nature, serving as the basis of the art while demonstrating moral truths and revealing the works of the Creator 4.

Taking a mystical approach, W.L. Wilmshurst argues that the literal meaning of geometry—"earth-measurement"—referred in ancient philosophy not to the physical globe, but to the fundamental soul-stuff or primordial substance from which humanity was made 5. In his view, the Masonic study of geometry is an allegory for investigating and understanding the spiritual nature and substance of human existence 5.
