On the Creation of the World (86-90)

And moreover, that most spirited of animals, the horse, is easily guided after he has been bridled; in order that he may not become frisky, and shake off the rein; and he hollows his back in an admirable manner to receive his rider and to afford him a good seat, and then bearing him aloft, he gallops at a rapid pace, being eager to arrive at and carry him to the place to which he is urging him. And the rider without any toil, but in the most perfect quiet, makes a rapid journey, by using the body and feet of another animal.

And any one who was inclined to dwell upon this subject might bring forward a great many other instances, to prove that there is no animal in the enjoyment of perfect liberty, and exempt from the dominion of man; but what has been already said is sufficient by way of example. We ought, however, not to be ignorant of this also, that it is no proof because man was the last created animal that he is the lowest in rank, and charioteers and pilots are witnesses of this;

for the charioteers sit behind their beasts of burden, and are placed at, their backs, and yet when they have the reins in their hands, they guide them wherever they choose, and at one time they urge them on to a swift pace, and at another time they hold them back, if they are going on at a speed greater than is desirable. And pilots again, sitting in the hindmost part of the ship, that is the stern are, as one may say, the most important of all the people in the ship, inasmuch as they have the safety of the ship and of all those who are in it, in their hands. And so the Creator has made man to be as it were a charioteer and pilot over all other animals, in order that he may hold the reins and direct the course of every thing upon earth, having the superintendence of all animals and plants, as a sort of viceroy of the principal and mighty King.

But after the whole world had been completed according to the perfect nature of the number six, the Father hallowed the day following, the seventh, praising it, and calling it holy. For that day is the festival, not of one city or one country, but of all the earth; a day which alone it is right to call the day of festival for all people, and the birthday of the world.

And I know not if any one would be able to celebrate the nature of the number seven in adequate terms, since it is superior to every form of expression. But it does not follow that because it is more admirable than anything that can be said of it, that on that account one ought to keep silence; but rather we ought to try, even if one cannot say everything which is proper, or even that which is most proper, at all events to utter such things as may be attainable by our capacities.
