Institutio Oratoria

But in view of the fact that the study of music has, from those remote times when Chiron taught Achilles down to our own day, continued to be studied by all except those who have a hatred for any regular course of study, it

It will, however, I think be sufficiently clear from the examples I have already quoted, what I regard as the value and the sphere of music in the training of an orator. Still I think I ought to be more emphatic than I have been in stating that the music which I desire to see taught is not our modern music, which has been emasculated by the lascivious melodies of our effeminate stage and has to no small extent destroyed such manly vigour as we still possessed. No, I refer to the music of old which was employed to sing the praises of brave men and was sung by the brave themselves. I will have none of your psalteries and viols, that are unfit even for the use of a modest girl. Give me the knowledge of the principles of music, which have power to excite or assuage the emotions of mankind.

We are told that Pythagoras on one occasion, when some young men were led astray by their passions to commit an outrage on a respectable family, calmed them by ordering the piper to change her strain to a spondaic measure, while Chrysippus selects a special tune to be used by nurses to entice their little charges to sleep.

Further I may point out that among the fictitious themes employed in declamation is one, doing no little credit to its author's learning, in which it is supposed that a piper is accused of manslaughter because he had played a tune in the Phrygian mode as an accompaniment to a sacrifice, with the result that the person officiating went mad and flung himself over a precipice. If an orator is expected to declaim on such a theme as this, which cannot possibly be handled without some knowledge

As regards geometry, [*](Geometry here includes all mathematics.) it is granted that portions of this science are of value for the instruction of children: for admittedly it exercises their minds, sharpens their wits and generates quickness of perception. But it is considered that the value of geometry resides in the process of learning, and not as with other sciences in the knowledge thus acquired. Such is the general opinion.

But it is not without good reason that some of the greatest men have devoted special attention to this science. Geometry has two divisions; one is concerned with numbers, the other with figures. Now knowledge of the former is a necessity not merely to the orator, but to any one who has had even an elementary education. Such knowledge is frequently required in actual cases, in which a speaker is regarded as deficient in education, I will not say if he hesitates in making a calculation, but even if he contradicts the calculation which he states in words by making an uncertain or inappropriate gesture with his fingers. [*]( There was a separate symbol for each number, depending on the hand used and the position of the fingers. See Class. Review, 1911, p. 72 ) Again linear geometry is frequently required in cases, as in lawsuits about boundaries and measurements.

But geometry and oratory are related in a yet more important way than this.

In the first place logical development is one of the necessities of geometry. And is it not equally a necessity for oratory? Geometry arrives at its conclusions from definite premises, and by arguing from what is certain proves what was previously uncertain. Is not this just what we do in speaking? Again are not the problems of geometry almost entirely solved by the
