Euclid Timeline

(c. 325 BCE – c. 270 BCE)

Euclid, often referred to as the 'Father of Geometry,' was an ancient Greek mathematician who lived around 300 BCE in Alexandria, Egypt. He is best known for his seminal work 'Elements,' one of the most influential textbooks in the history of mathematics. His systematic approach to geometry laid the groundwork for mathematical teaching for over two millennia. Less

Life and Legacy of Euclid

Euclid, father of geometry, active in Alexandria

300 BC

Considered the 'father of geometry', Euclid is chiefly known for the Elements treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. Very little is known of his life.

Non-Euclidean geometries discovered, ending Euclid's dominance

1800 - 1830

The geometrical system established by the Elements long dominated the field until the early 19th century; today it is often referred to as 'Euclidean geometry' to distinguish it from other non-Euclidean geometries discovered in the early 19th century.

Euclid's namesakes: ESA space telescope, crater, asteroid

2026

Among Euclid's many namesakes are the European Space Agency's (ESA) Euclid space telescope, the lunar crater Euclides, and the minor planet 4354 Euclides, reflecting the enduring influence of the ancient geometer.

The Elements

Elements partly in circulation by 3rd century BC

300 BC - 201 BC

The Elements is speculated to have been at least partly in circulation by the 3rd century BC, as Archimedes and Apollonius take several of its propositions for granted; however, Archimedes employs an older variant of the theory of proportions than the one found in the Elements.

Galen cites the Elements as a standard school text

150

The oldest extant direct citations to the Elements in works whose dates are firmly known are from the 2nd century AD, by Galen and Alexander of Aphrodisias; by this time it was a standard school text.

200

Alongside Galen, Alexander of Aphrodisias provided one of the oldest extant direct citations to the Elements in works whose dates are firmly known, confirming that by this time it was a standard school text.

Book 2 interpreted as 'geometric algebra'

1900 - 1970

Book 2 of the Elements is traditionally understood as concerning 'geometric algebra', though this interpretation has been heavily debated since the 1970s; critics describe the characterization as anachronistic, since the foundations of even nascent algebra occurred many centuries later.

Ancient and Medieval Reception

Earliest original reference to Euclid in Apollonius' Conics

200 BC

The earliest original reference to Euclid appears in Apollonius' prefatory letter to the Conics (early 2nd century BC), where Apollonius notes that Euclid had not fully made the synthesis of the locus on three and four lines.

Valerius Maximus confuses Euclid with Eudoxus

30 AD

Valerius Maximus, the 1st century AD Roman compiler of anecdotes, mistakenly substituted Euclid's name for Eudoxus (4th century BC) as the mathematician to whom Plato sent those asking how to double the cube.

Pappus of Alexandria records anecdotes about Euclid

320

A few anecdotes about Euclid come from Pappus of Alexandria in the early 4th century AD, forming part of the sparse traditional narrative about the mathematician's life.

Proclus writes account of Euclid's life

450 - 485

The traditional narrative of Euclid's life mainly follows the 5th century AD account by Proclus in his Commentary on the First Book of Euclid's Elements. Both Proclus' and Pappus' accounts were written in the 5th century AD, neither indicates its source, and neither appears in ancient Greek literature.

Euclid conflated with Euclid of Megara in Byzantine sources

500 - 1300

Perhaps on the basis of Valerius Maximus' mention of a mathematical Euclid roughly a century early, Euclid became mixed up with Euclid of Megara in medieval Byzantine sources (now lost), eventually leading the mathematician to be ascribed details of both men's biographies and described as Megarensis ('of Megara').

1300

The Byzantine scholar Theodore Metochites (c. 1300) explicitly conflated the mathematician Euclid with Euclid of Megara, perpetuating the confusion between the two figures.

Early Modern Publications

Erhard Ratdolt prints editio princeps of Campanus' Elements

1482

Printer Erhard Ratdolt's 1482 editio princeps of Campanus of Novara's Latin translation of the Elements also explicitly conflated the two Euclids.

Bartolomeo Zamberti publishes translation of the Elements

1505

After the mathematician Bartolomeo Zamberti appended most of the extant biographical fragments about either Euclid to the preface of his 1505 translation of the Elements, subsequent publications passed on the identification of the mathematician with Euclid of Megara.

First English edition of the Elements published

1570

The first English edition of the Elements was published in 1570 by Henry Billingsley and John Dee, bringing Euclid's foundational treatise to English readers.

Oliver Byrne publishes colored diagram edition of the Elements

1847

Oliver Byrne published a well-known version of the Elements entitled The First Six Books of the Elements of Euclid in Which Coloured Diagrams and Symbols Are Used Instead of Letters for the Greater Ease of Learners, which included colored diagrams intended to increase its pedagogical effect.

Key Facts

  1. Euclid's most famous work, 'Elements,' consists of 13 books covering geometry, number theory, and mathematical logic.
  2. 'Elements' served as the primary textbook for teaching mathematics for over 2,000 years, remaining in use until the early 20th century.
  3. Euclid taught at Alexandria under the reign of Ptolemy I, establishing the city as a major center of mathematical scholarship.
  4. He introduced the axiomatic method, deducing theorems from a small set of self-evident axioms and postulates, which became a model for rigorous reasoning.
  5. Little is known about Euclid's personal life; even his birth and death dates are approximate, based on references from later scholars such as Proclus.
