The man from Samos
Pythagoras was born around 570 BCE on the island of Samos, in the Aegean Sea. Before founding his own school, he travelled widely, to Egypt and as far as Babylon, absorbing the mathematical, astronomical and religious knowledge of the ancient East.
Around 530 BCE he settled in Croton, in Magna Graecia (today's southern Italy), and founded a community that was at once philosophical, scientific and spiritual: the Pythagorean brotherhood. There, numbers, music and the harmony of the cosmos were studied within a demanding way of life. Pythagoras himself left no writings: his thought comes to us through his disciples.
“All is number”
The central insight of the Pythagoreans fits in a single phrase: number is the principle of all things. On discovering that the most harmonious musical intervals correspond to simple ratios between string lengths (the octave, the fifth, the fourth), they saw in number the hidden structure of the universe, from music to the paths of the stars.
Their sacred figure is the tetractys: four rows of dots (1, 2, 3 and 4) adding up to 10, the perfect number. Each number carries a meaning: unity, duality, harmony, matter. Long before any “numerology”, number was already, for them, a symbolic language as much as a quantity.
The theorem that bears his name (the square of the hypotenuse) is only one facet of this vision: for the Pythagoreans, geometry, arithmetic, music and astronomy formed a single body of knowledge.
From number to numerology
It is this legacy (number as a key to reading the world and the self) that Western numerology takes up. Reducing a name or a date of birth to a number, then reading its meaning, extends the Pythagorean idea that each number has its own quality, a vibration.
In all honesty: the table that maps each letter to a digit is far more recent (it took shape in the 19th and 20th centuries) and was never taught by Pythagoras. We own it for what it is: a symbolic tradition inspired by his thought, not a science he founded.
