25. But now as for the senses that are created within the body, such as are of celestial and heavenly extraction, and which by divine assistance affect the understanding of men by means of harmony,—namely, sight and hearing,—do by the very light and voice express harmony. And others which are their attendants, so far as they are senses, likewise exist by harmony; for they perform none of their effects without harmony; and although they are inferior to the other two, they are not independent of them. Nay, those two also, since they enter into human bodies at the very same time with God himself, claim by reason a vigorous and incomparable nature. 26. Manifest from hence therefore it is, why the ancient Greeks, with more reason than others, were so careful to teach their children music. For they deemed it requisite by the assistance of music to form and compose the minds of youth to what was decent, sober, and virtuous; believing the use of music beneficially efficacious to incite to all serious actions, especially to the adventuring upon warlike dangers. To which purpose they made use of pipes or flutes when they advanced in battle array against their enemies; like the Lacedaemonians, who upon the same occasion caused the Castorean melody to be played before their battalions. Others inflamed their courage with harps, playing the same sort of harmony when they went to look danger in the face, as the Cretans did for a long time. Others, even to our own times, continue to use the trumpet. The Argives made use of flutes at their wrestling matches called Stheneia; which sort of sport was first instituted in honor of Danaus, but afterwards consecrated to Jupiter Sthenius, or Jupiter the Mighty. And now at this day it is the custom to make use of flutes at the games called Pentathla, although there is now nothing exquisite or antique, nothing like what was customary among men of old time, like the song composed by Hierax for this very game; still, even though it is sorry stuff and nothing exquisite, it is accompanied by flute-music. 27. But among the more ancient Greeks, music in theatres was never known, for they employed their whole musical skill in the worship of the Gods and the education of youth; at which time, there being no theatres erected, music was yet confined within the walls of their temples, as being that with which they worshipped the supreme Deity and sang the praises of virtuous men. And it is probable that the word θέατρον, at a later period, and θεωρεῖν (_to behold_) much earlier, were derived from θεός (_God_). But in our age is such another face of new inventions, that there is not the least remembrance or care of that use of music which related to education; for all our musicians make it their business to court the theatre Muses, and study nothing but compositions for the stage.
