Besides the enthusiasm that developed in the Latin and Byzantine worlds in the Middle Ages for Pythagorean numerology, the Pythagorean tradition of perfect numbers inspired profound scholarship in mathematics. In the 13th century Leonardo of Pisa, better known as Fibonacci, published the Libre quadratorum (The Book of Squares). Fibonacci had ...
Numerology (known before the 20th century as arithmancy) is the belief in an occult, divine or mystical relationship between a number and one or more coinciding events. It is also the study of the numerical value, via an alphanumeric system, of the letters in words and names.
They went back to the later period of Plato's thought, the period when Plato endeavoured to combine his doctrine of Ideas with Pythagorean number theory, and identified the good with the monad (which would give rise to the Neoplatonic concept of "the One"), the source of the duality of the infinite and the measured with the resultant scale of ...

Little is known about the life of Nicomachus except that he was a Pythagorean who came from Gerasa. [1] His Manual of Harmonics was addressed to a lady of noble birth, at whose request Nicomachus wrote the book, which suggests that he was a respected scholar of some status. [2]
[7] The interest in the question may suggest some knowledge of the Pythagorean theorem, though the papyrus only shows a straightforward solution to a single second degree equation in one unknown. In modern terms, the simultaneous equations x 2 + y 2 = 100 and x = (3/4) y reduce to the single equation in y : ((3/4) y ) 2 + y 2 = 100 , giving the ...
In his preface to his book On the Revolution of the Heavenly Spheres (1543), Nicolaus Copernicus cites various Pythagoreans as the most important influences on the development of his heliocentric model of the universe, [275] [279] deliberately omitting mention of Aristarchus of Samos, a non-Pythagorean astronomer who had developed a fully ...
