born around 365, died around 300 B.C.

Little is known about his life. According to Proclus he was younger than the first pupils of Plato, whose research he used, and older than Archimedes, who took his postulates for granted. During the rule of Ptolemy I he worked in Alexandria. Pappos extols his benevolence to other mathematicians and his modesty in not exaggerating the importance of his own achievements.
His main work is the Elements, which probably originated around 325 B.C. and exerted a decisive influence on the development of mathematics well into the 19th century. These elements are exemplary in composition and structure throughout the entire work and, as Aristotle claimed any demonstrative science must, starts with definitions, postulates and axioms from which further theses are derived deductively in the form of problems or theorems. The elements are essentially a summary of the geometric knowledge accumulated by his predecessors, but this hardly lessens Euclid’s importance and uniqueness in science.
Also preserved is his Data, which deals with planimetric questions and supplements the Elements. He addresses important questions of mathematical astronomy in his Phaenomena. In Optica the laws of perspective are described and the apparent size and shape of figures studied from varying positions and distances. The Sectio canonis portrays the Pythagorean theory of music in the manner of the Elements. All of Euclid’s works are known only through ancient testimony. The attribution of a Cataoptrics (theory of reflections) to Euclid is questionable. It is also unclear whether Euclid was actually the author of a book on mechanics (De levi et ponderoso) in Arabic that was preserved in Latin translation.
