What is "aristoxenus"

Aristoxenus of Tarentum (; b. c. 375, fl. 335 BCE) was a Greek Peripatetic philosopher, and a pupil of Aristotle. Most of his writings, which dealt with philosophy, ethics and music, have been lost, but one musical treatise, Elements of Harmony (Greek: Ἁρμονικῶν στοιχείων; Latin: Elementa harmonica), survives incomplete, as well as some fragments concerning rhythm and meter. The Elements is the chief source of our knowledge of ancient Greek music.

Aristoxenus ( Gr. ) was a Greek physician of Asia Minor who was quoted by Caelius Aurelianus. He was a pupil of Alexander Philalethes and contemporary of Demosthenes Philalethes, and must therefore have lived around the 1st century. He was a follower of the teachings of Herophilos, and studied at the celebrated Herophilean school at the village of Men-Carus, between Laodicea and Carura. He wrote a work (On the Herophilean Sect, Latin: De Herophili Secta), of which the thirteenth book is quoted by Galen, but which is no longer extant.
