Geometry of the Hagia Sophia, Constantinople

The current dome was built when the original collapsed after an earthquake, and its design was based on the geometry of the building it was built upon. This shows Ad Quadratum geometry

The Ad Quatratum system:





Ad Quadratum was apparently considered to be more sacred than Ad Triangulum because it yielded the 8-pointed 'star of Christ' instead of the 6-pointed star of Ad Triangulum. Sacred Geometry (that is, the geometry of Cathedrals and other sacred spaces) seems to have employed Ad Quad. more than ad Triang. The daisy wheel can be considered a form of Ad Triangulum, as it employs the same principles and yield the same geometry.


Even the Pagan-built Pantheon in Rome employs this ancient Euclidean Geometry
