"The Samian teacher [Pythagoras], the glory of the Latin land, once raised the Monad into the Tetrad, and the Tetrad within the Monad. He taught how the Monad migrates into the Dyad, the Dyad into the Triad, and the Triad into the Tetrad. He said that this, finally, holds the limit and the number of things..."
Giordano Bruno's De triplici minimo et mensura explore the "Monad" as the fundamental unit of the universe. He describes how all complexity and geometry, from lines to 3D shapes, evolve from this single, indivisible point of origin.
"Initially, with the key placed before it, every proposed figure can be seen converted into a triangle. When its center flows down from the ribs (sides) which will be made equal into the middle of the sides. And the produced line concurs with the remaining straight point, which is produced long as one from the number of sides." Bruno presents the "Key of Transmutations," illustrating how different geometric forms can be converted into one another while preserving their core essence. The diagram acts as a philosophical tool to show the underlying unity and constant transformation of all matter in an infinite universe.
