Pythagoras is famous for his use of numerical and geometrical keys, which he illustrated by reference to the geometrical figures, the musical scale, astronomy, etc. He is supposed to have "discovered" the Divine Section, the regular polyhedra, and the proposition relating to the square of the hypotenuse; what he did was to show that these were keys to the interpretation of mysteries. Porphyry reports that the numerals of Pythagoras were "hieroglyphical symbols by means whereof he explained ideas concerning the nature of things: (Vita Pythag) or, Blavatsky adds, "the origin of the universe" (SD 1:361). His tetraktys is a gem of condensed esoteric symbolism. The influence of his school may be traced in subsequent Greek history, inspiring such characters as Epaminondas; "It was Pythagoras who was the first to teach the heliocentric system, and who was the greatest proficient in geometry of his century. It was he also who created the word 'philosopher,' composed of two words meaning a 'lover of wisdom' -- philosophos. As the greatest mathematician, geometer and astronomer of historical antiquity, and also the highest of the metaphysicians and scholars, Pythagoras has won imperishable fame. He taught reincarnation as it is professed in India and much else of the Secret Wisdom" (TG 266).
