The New International Encyclopædia/Aristides Quintilianus

ARISTIDES QUINTILIANUS (Gk. Άρωτείοης Κοϊντιλιανός, Aristeides Kointilianos). A Greek grammarian of about the First Century A.D., and author of a treatise on music which is one of the most valuable of all ancient discussions of that subject. In the first part it treats of the principles of harmonics and rhythm, as laid down by Aristoxenus, but later introduces the Neo-Platonic ideas of the moral effects of music and the connection between musical intervals and the harmony of the universe. It was originally edited by Meibomius, and in 1882 by Jahn. Consult Cäsar, Die Grundzüge der griechischen Rythmik im Anschluss an Aristeides (Marburg, 1861).
