All About Euclid

Euclid was born in 300 BC, Alexandria, Egypt. Euclid was the most prominent mathematician in Greece. According to Proclus, he taught in Alexandria when Ptolemy I Soter was ruling Egypt. Many translators and editors confused Euclid with the philosopher Eukleides of Megara. Euclid's famous words say "There is no royal road to geometry."

Euclid was a mathematician whose third century B.C. textbook Elements served as the western world's unchallenged standard for two millennia. Not much is known about Euclid's life or physical appearance, and what little is known about his career comes from inferences. It is generally agreed that he taught geometry in Hellenistic Egypt, at Alexandria during the reign of Ptolemy I, between 305 and 285 B.C. He is credited with the thirteen volumes of Elements, a work that accumulated mathematical knowledge and codified it into a deductive system of proofs. Euclidean geometry was the geometry until the 19th century, when mathematicians began to challenge Euclid's assumptions about parallel lines, for example, when considering measurements over very large distances of, say, billions of light years.
