Hence Plato, and, before his time, the Pythagoreans, called music philosophy. They maintained that the world subsisted by harmony, and considered every kind of music to be the work of the gods. It is thus that the muses are regarded as deities, and Apollo has the name of President of the Muses, and all poetry divine, as being conversant about the praises of the gods. Thus also they ascribe to music the formation of manners, as everything which refines the mind approximates to the power of the gods.

The greater part of the Greeks attribute to Bacchus, Apollo, Hecate, the Muses, and Ceres, everything connected with orgies and Bacchanalian rites, dances, and the mysteries attended upon initiation. They call also Bacchus, Dionysus, and the chief Dæmon of the mysteries of Ceres.¹ The carrying about of branches of trees, dances, and initiations are common to the worship of these gods. But with respect to Apollo and the Muses, the latter preside over choirs of singers and dancers; the former presides both over these and divination. All persons instructed in science, and particularly those who have cultivated music, are ministers of the Muses; these and also all who are engaged in divination are ministers of Apollo. Those of Ceres, are the Mystæ, torch-bearers and Hierophants; of Dionysus, Seileni, Satyri, Tityri, Bacchæ Lenæ, Thyiæ, Mimallones, Naïdes, and Nymphæ, as they are called.
