Nicomachus of Gerasa (c. 60-c. 120 CE) was a Greek mathematician and music theorist in the Pythagorean tradition, from Gerasa (modern Jerash). His 'Introduction to Arithmetic' became a standard textbook on the theory of numbers, treating numbers philosophically rather than as a tool for calculation, and he also wrote a 'Manual of Harmonics' on music. His work was influential well into the Middle Ages.
