**The Greek mathematician Euclid of Alexandria is considered to be the father of geometry.** His mathematical and geometric treatise "Elements" is one of the most influential works in mathematics as well as one of the most successful textbooks ever written.

Euclid was alive during the reign of Ptolemy I from 323 to 283 B.C. He published "Elements" around 300 B.C., and it soon became the main textbook for teaching geometry. In "Elements," Euclid uses a small set of axioms and deductive logic to construct the framework of what is now known as Euclidean geometry.

"Elements" was one of the first mathematical works to be printed after the invention of the printing press and is thought to be second only to the Bible in the number of editions published.
