Nicomachus of Gerasa

Nicomachus was a Greek mathematician and philosopher from Gerasa, a city in the Roman province of Syria, near modern Jerash in Jordan. Almost nothing is known about his life, and his dates can only be estimated from the authors he cites and those who cite him; he probably lived in the late first and early second centuries AD. He belonged to the Neopythagorean school, which revived the teaching of Pythagoras that number lies at the heart of reality. His Introduction to Arithmetic treats numbers as objects of philosophical study rather than tools of calculation, classifying them as odd and even, prime and composite, perfect, deficient and abundant, and exploring ratios and figurate numbers. He also wrote a Manual of Harmonics on the mathematics of music. Boethius adapted the Introduction into Latin, and through that version it became a standard school text of the arithmetic in the medieval quadrivium for roughly a thousand years.
