Plato is important in the history of mathematics for inspiring and guiding others.^[31] His Platonic Academy, in Athens, became the mathematical center of the world in the 4th century BCE, and it was from this school that the leading mathematicians of the day, such as Eudoxus of Cnidus, came.^[32] Plato also discussed the foundations of mathematics,^[33] clarified some of the definitions (e.g. that of a line as "breadthless length"), and reorganized the assumptions.^[34] The analytic method is ascribed to Plato, while a formula for obtaining Pythagorean triples bears his name.^[32]
