Pythagoras
Pythagoras began as a man who may have been half philosopher, half wonder-worker; his followers turned him into proof that the cosmos itself could be read as a sacred ratio.

Timeline
Birth of Pythagoras on Samos
**570 BC** — Later tradition places Pythagoras’ birth around this date on Samos, an island embedded in the trade routes and cultural exchanges of the eastern Aegean. The historical details are uncertain, but the setting matters: this was a world where travel, ritual, and inquiry could cross paths naturally.
Formation of Pythagoras’ itinerant reputation
**540 BC** — Ancient biographies describe journeys to Egypt, Phoenicia, and elsewhere, though the evidence is mixed and often legendary. Whether literal or embroidered, these travels helped make Pythagoras appear as a bearer of foreign wisdom and ritual expertise.
Establishment of the Pythagorean community at Croton
**520 BC** — Pythagoras is said to have founded a disciplined brotherhood in Croton, in Magna Graecia. This was not merely a school of argument but a way of life combining instruction, purification, and civic influence.
Pythagorean mathematical-musical doctrine takes shape
**500 BC** — The tradition links the Pythagoreans to the discovery that musical intervals correspond to simple ratios. Whether or not Pythagoras himself made the discovery, the association became central to the school’s claim that number structures reality.
Death of Pythagoras
**495 BC** — Pythagoras likely died around this date, though ancient accounts disagree about the circumstances. His death did not end the movement; it intensified the process by which his name became the emblem of a school and a life-form.
Philolaus systematizes Pythagorean doctrine
**470 BC** — Philolaus represents an important stage in the transformation of Pythagorean themes into more explicit philosophy. His accounts of limit, the unlimited, and cosmic order show the school moving toward articulated metaphysics.
Anti-Pythagorean conflict in Magna Graecia
**430 BC** — Ancient sources preserve memories of political backlash against Pythagorean communities in southern Italy. The precise chronology is debated, but the episode shows how a philosophical brotherhood could become entangled in civic conflict.
Plato absorbs Pythagorean themes in the Timaeus
**380 BC** — Plato’s cosmology takes up mathematical proportion, order, and the intelligibility of the heavens in ways strongly resonant with the Pythagorean inheritance. The dialogue helps move Pythagorean number into the center of later metaphysics.
Aristotle critiques Pythagorean number theory
**325 BC** — In the Metaphysics and related works, Aristotle records and criticizes Pythagorean claims about number as principle. His treatment becomes one of the main channels through which later generations encountered the school.
Renaissance revival of Pythagorean harmony
**1560** — Early modern thinkers renewed interest in mathematical harmony, cosmic proportion, and number symbolism. Pythagoras reappeared less as a historical person than as a witness for the beauty of mathematical order.
Kepler publishes Astronomia nova
**1609** — Kepler’s astronomical work helped transform the ancient dream of cosmic harmony into mathematically precise celestial science. The Pythagorean impulse survived here in altered form: the heavens remained readable as structure, but now under stricter empirical constraint.
Continued scholarly reassessment of Pythagoras
**2020** — Modern scholarship continues to separate historical Pythagoras from later Pythagoreanism while recognizing the school’s profound influence. The question remains live: how much of philosophy’s mathematical imagination begins with him?
