Thales of Miletus Geometry begins with proof

Thales is often regarded as one of the earliest Greek mathematicians. He helped move mathematical thought from practical rule-of-thumb methods toward logical reasoning and proof.

Pythagoras Number, harmony, philosophy

Pythagoras and the Pythagorean tradition linked number with structure, harmony, and the nature of reality. His name remains associated with one of the most famous results in geometry.

Euclid Father of geometry

Euclid's Elements became one of the most influential works in the history of mathematics, formalising geometry through axioms, logic, and proof.

Archimedes Mathematics in motion

Archimedes united geometry, mechanics, and physical reasoning. His work on area, volume, buoyancy, and engineering remains foundational.

Eratosthenes Measurement of the Earth

Eratosthenes famously estimated the circumference of the Earth with striking accuracy, demonstrating the power of geometry applied to the natural world.

Democritus Atomic reasoning and abstraction

Democritus is remembered for his atomistic philosophy, proposing that reality is composed of indivisible units and helping shape later scientific thinking.

Hipparchus Astronomy and trigonometric thinking

Hipparchus advanced astronomical measurement and is closely associated with the development of early trigonometric methods.

Apollonius of Perga Master of conic sections

Apollonius developed the theory of conic sections, a body of work that later became central to astronomy, optics, and modern mathematical physics.

Hero of Alexandria Geometry and ingenious devices

Hero combined mathematics with mechanics, producing formulas, devices, and engineering concepts that show the practical side of Hellenic scientific thought.

Eudoxus of Cnidus Theory of proportion and celestial models

Eudoxus contributed deeply to proportion theory and mathematical astronomy. Because no standard surviving portrait is firmly established, this card uses a historical online image of his homocentric-spheres model.

Hypatia Scholar of Alexandria

Hypatia stands as a major intellectual figure of late antiquity, associated with mathematics, astronomy, philosophical teaching, and the preservation of classical knowledge.

Diophantus Proto-algebraic insight

Diophantus is often associated with early algebraic reasoning through symbolic treatment of equations and number problems that still inspire mathematics today.
