Aristides Quintilianus

Aristides Quintilianus (Greek: Ἀριστείδης Κοϊντιλιανός) was the Greek author of an ancient musical treatise, Perì musikês (Περί Μουσικῆς, i.e. On Music; Latin: De Musica), who according to the Encyclopaedia Britannica (1911) probably lived in the third century AD, but according to the Complete Encyclopaedia of Music (1880) may have live around 130 AD.

According to Marcus Meibomius, in whose collection (Antiq. Musicae Auc. Septem, 52) this work is printed, it contains everything on music that is to be found in antiquity (except for Aristoxenus)
