Greek Pythagoreanism, founded by Pythagoras in the 6th century BCE, is a philosophical and religious movement that combines mathematics, mysticism, and cosmology. Its central belief revolves around the idea that numbers and mathematical ratios are the fundamental principles of the universe. The famous Pythagorean theorem, which states "a² + b² = c²" for right-angled triangles, is one of its most enduring contributions to mathematics.
Greek Pythagoreanism is a philosophical and mathematical school of thought that originated with Pythagoras, a Greek philosopher and mathematician. The Pythagorean school focused on the study of numbers, harmony, and the cosmos.
Foundations of Pythagoreanism
Pythagoreanism revolves around key principles such as the significance of numbers, mathematical relationships, and their connections to the universe. Pythagoreans believed that numbers were the fundamental building blocks of reality.
Greek Pythagoreanism: A philosophical and religious movement attributed to Pythagoras, involving the study of mathematics, music, and astronomy as means of understanding the universe.
A famous example of Pythagoreanism is the belief in the harmony of the spheres, which posits that celestial bodies move according to mathematical equations, producing a symphony of music that is inaudible to the human ear.
Pythagorean Theorem
One of the most well-known contributions of Pythagoreanism is the Pythagorean Theorem. This theorem states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Mathematically, this is expressed as:
\[a^2 + b^2 = c^2\]
a and b are the lengths of the legs of the triangle.
c is the length of the hypotenuse.
The Pythagorean Theorem is not just an abstract principle; it has practical applications in various fields, including geometry, architecture, and even modern physics. For example, it is used in navigation and in determining the shortest distance between two points.
Note that the Pythagorean Theorem is only applicable to right-angled triangles.
Numerology in Pythagoreanism
Pythagoreanism places significant emphasis on numerology, the belief that numbers have mystical and divine meanings. The number one, for instance, represented unity and origin; two signified duality or partnership; three represented harmony; four, stability.
The Tetractys of the Decad is a triangular figure made up of ten points arranged in four rows. This figure was highly significant to the Pythagoreans, symbolizing the perfection of number 10 (1 + 2 + 3 + 4 = 10) and the harmony of the universe.

Pythagorean School of Thought
The Pythagorean School of Thought, established by Pythagoras, is a cornerstone of ancient Greek philosophy and mathematics. Its teachings extend beyond mathematics to cosmology, music, and ethics.
Core Principles
Pythagoreanism emphasizes several core principles:
Numerology: Numbers are fundamental to understanding the universe.
Harmony: The cosmos is governed by mathematical relations.
Transmigration of Souls: The soul is eternal and reincarnates.
Pythagorean Theorem
The Pythagorean Theorem is a fundamental principle in geometry. In a right-angled triangle, the theorem states:
\[a^2 + b^2 = c^2\]
a and b are the lengths of the legs.
c is the length of the hypotenuse.
For a triangle with legs a = 3 and b = 4, the hypotenuse c is calculated as follows:
\[3^2 + 4^2 = c^2\]
\[9 + 16 = c^2\]
\[c^2 = 25\]
\[c = 5\]
The Pythagorean Theorem's applications extend to various fields such as architecture, where it's used to ensure structures are properly aligned. For example, ancient builders used the theorem to create accurate right angles when constructing temples and monuments.
The Pythagorean Theorem can only be applied to right-angled triangles.
Numerology and Symbolism
Pythagoreanism is deeply rooted in numerology. Each number was endowed with symbolic meanings:
1: Unity and origin
2: Duality and balance
3: Harmony
4: Stability
The Tetractys, a triangular figure composed of ten points arranged in four rows (1, 2, 3, 4), symbolized the harmony and order of the universe. The sum of the first four numbers (1 + 2 + 3 + 4 = 10) represents completeness.
Tetractys of the Decad: A triangular figure made up of ten points arranged in four rows, symbolizing the harmony and perfection of the number ten.
The Pythagorean approach to numbers influenced later mathematical and philosophical developments. Their numerological insights laid the groundwork for the field of number theory and impacted early Greek philosophy, blending numerical relationships with metaphysical concepts.
Greek Philosophers Pythagoreanism
Greek Pythagoreanism is an ancient philosophical school founded by Pythagoras. This school explores the connections between mathematics, cosmology, and spiritual beliefs. The Pythagoreans were known for their emphasis on numbers and harmony in the universe.
Key Characters in Greek Pythagoreanism
Pythagoreanism includes several important figures who contributed to its development and spread. These key characters played significant roles in shaping Pythagorean beliefs and teachings.
Pythagoras: The founder of the Pythagorean school, known for his work in mathematics, especially the Pythagorean Theorem.
Other notable figures include:
Hippasus: Known for discovering irrational numbers.
Philolaus: Introduced the concept of the Earth revolving around a 'Central Fire.'
Archytas: Made significant contributions to mathematics and mechanics.
An example of Pythagorean influence is Hippasus' discovery of irrational numbers. This discovery showed that not all quantities could be expressed as ratios of integers, challenging the Pythagorean belief in the absoluteness of numbers.
Hippasus' discovery of irrational numbers reportedly led to conflict within the Pythagorean community.
Philolaus' concept of the Earth revolving around a 'Central Fire' predated the heliocentric model proposed by Copernicus. This idea suggested that the universe was not geocentric, marking a significant shift in astronomical thought.
Major Themes of Pythagorean Philosophy
Pythagorean philosophy encompasses a range of themes, focusing on the relationship between mathematics and the cosmos, as well as ethical and spiritual practices.
Key themes include:
Numerology: The belief that numbers have mystical and cosmic significance.
Harmony: The idea that mathematical relationships create harmony in the universe, including music.
Transmigration of Souls: The belief in the reincarnation and eternal nature of the soul.
An example of Pythagorean numerology is the Tetractys, a triangular figure composed of ten points arranged in four rows. This symbol represents the harmony and order of the universe.
Tetractys: A triangular figure made up of ten points arranged in four rows, symbolizing the harmony of the universe.
The Tetractys was considered sacred and used in Pythagorean rituals and oaths.
Pythagorean harmony extended beyond mathematics to music, where the Pythagoreans discovered the mathematical ratios that correspond to musical intervals. This link between math and music is a cornerstone of the Pythagorean belief system and highlights their interdisciplinary approach.
