Pappus of Alexandria is one of the most important mathematicians of ancient Greek time, known for his work Synagoge or Collection (c. 340).
He was born at Alexandria in Egypt. Although very little is known about his life, the written records suggest he was a teacher.
Synagoge, his best-known work, is a compendium of mathematics of which eight volumes survive. It covers a wide range of topics, including geometry, recreational mathematics, doubling the cube, polygons and polyhedra.
In geometry, there are several theorems that are known by the generic name Pappus's Theorem, attributing them to Pappus of Alexandria. They include:
- Pappus's centroid theorem,
- the Pappus chain,
- Pappus's harmonic theorem, and
- Pappus's hexagon theorem.
