Euclid's "Elements" (sometimes: "The Elements", "Stoicheia") is a large set of math books about geometry, written by the ancient Greek mathematician known as Euclid (c.325 BC–265 BC) in Alexandria (Egypt) circa 300 BC. The set has 13 volumes, or sections, and has been printed often as 13 physical books (numbered I-XIII), rather than one large book. It has been translated into Latin, with the title ""Euclidis Elementorum"". It is the most famous mathmetical text from ancient times.
