[78] As then, those who make a feast do not invite their guests to the entertainment before they have provided everything for festivity, and as those who celebrate gymnastic or dramatic contests, before they assemble the spectators, provide themselves with an abundance of competitors and spectacles, and sweet sounds, with which to fill the theatres and the stadia; so in the same manner did the Ruler of all, as a man proposing games, or giving a banquet and being about to invite others to feast and to behold the spectacle, first provide everything for every kind of entertainment, in order that when man came into the world he might at once find a feast ready for him, and a most holy theatre; the one abounding with everything which the earth, or the rivers, or the sea, or air, brings forth for use and enjoyment, and the other being full of every description of light, which has either its essence or its qualities admirable, and its motions and revolutions worthy of notice, being arranged in perfect order, both as to the proportions of its numbers, and the harmony of its periods. And a man would not be far wrong who should say that in all these things there might be discovered that archetypal and real model music, the images of which the subsequent generations of mankind engraved in their own souls, and in this way handed down the art which is the most necessary and the most advantageous to human life.
