They add, then, the twelve cubits, agreeably to the revolution of the twelve months, in the annual circle, during which the earth produces and matures all things; adapting itself to the four seasons. And the table, in my opinion, exhibits the image of the earth, supported as it is on four feet, summer, autumn, spring, winter, by which the year travels. Wherefore also it is said that the table has “wavy chains;”[1047] either because the universe revolves in the circuits of the times, or perhaps it indicated the earth surrounded with ocean’s tide.

Further, as an example of music, let us adduce David, playing at once and prophesying, melodiously praising God. Now the Enarmonic[1048] suits best the Dorian harmony, and the Diatonic the Phrygian, as Aristoxenus says. The harmony, therefore, of the Barbarian psaltery, which exhibited gravity of strain, being the most ancient, most certainly became a model for Terpander, for the Dorian harmony, who sings the praises of Zeus thus:

“O Zeus, of all things the Beginning, Ruler of all;

O Zeus, I send thee this beginning of hymns.”

The lyre, according to its primary signification, may by the psalmist be used figuratively for the Lord; according to its secondary, for those who continually strike the chords of their souls under the direction of the Choir-master, the Lord. And if the people saved be called the lyre, it will be understood to be in consequence of their giving glory musically, through the inspiration of the Word and the knowledge of God, being struck by the Word so as to produce faith. You may take music in another way, as the ecclesiastical symphony at once of the law and the prophets, and the apostles along with the gospel, and the harmony which obtained in each prophet, in the transitions of the persons.

But, as seems, the most of those who are inscribed with the Name,[1049] like the companions of Ulysses, handle the word unskilfully, passing by not the Sirens, but the rhythm and the melody, stopping their ears with ignorance; since they know that, after lending their ears to Hellenic studies, they will never subsequently be able to retrace their steps.

But he who culls what is useful for the advantage of the catechumens, and especially when they are Greeks (and the earth is the Lord’s, and the fulness thereof[1050]), must not abstain from erudition, like irrational animals; but he must collect as many aids as possible for his hearers. But he must by no means linger over these studies, except solely for the advantage accruing from them; so that, on grasping and obtaining this, he may be able to take his departure home to the true philosophy, which is a strong cable for the soul, providing security from everything.

Music is then to be handled for the sake of the embellishment and composure of manners. For instance, at a banquet we pledge each other while the music is playing;[1051] soothing by song the eagerness of our desires, and glorifying God for the copious gift of human enjoyments, for His perpetual supply of the food necessary for the growth of the body and of the soul. But we must reject superfluous music, which enervates men’s souls, and leads to variety,—now mournful, and then licentious and voluptuous, and then frenzied and frantic.

The same holds also of astronomy. For treating of the description of the celestial objects, about the form of the universe, and the revolution of the heavens, and the motion of the stars, leading the soul nearer to the creative power, it teaches to quickness in perceiving the seasons of the year, the changes of the air, and the appearance of the stars; since also navigation and husbandry derive from this much benefit, as architecture and building from geometry. This branch of learning, too, makes the soul in the highest degree observant, capable of perceiving the true and detecting the false, of discovering correspondences and proportions, so as to hunt out for similarity in things dissimilar; and conducts us to the discovery of length without breadth, and superficial extent without thickness, and an indivisible point, and transports to intellectual objects from those of sense.

The studies of philosophy, therefore, and philosophy itself, are aids in treating of the truth. For instance, the cloak was once a fleece; then it was shorn, and became warp and woof; and then it was woven. Accordingly the soul must be prepared and variously exercised, if it would become in the highest degree good. For there is the scientific and the practical element in truth; and the latter flows from the speculative; and there is need of great practice, and exercise, and experience.
