Greek mathematics, as that term is used in this article, is the
mathematics written in
Greek, developed from the 7th century BC to the 4th century AD around the shores of the Eastern
Mediterranean. Greek mathematicians lived in cities spread over the entire Eastern Mediterranean, from Italy to North Africa, but were united by
culture and
language. Greek mathematics of the period following
Alexander the Great is sometimes called
Hellenistic mathematics. The word "mathematics" itself derives from the ancient Greek
μάθημα (
mathema), meaning "subject of instruction". The study of mathematics for its own sake and the use of generalized mathematical theories and proofs is the key difference between Greek mathematics and those of preceding civilizations.
