Institutio Oratoria

Finally there was actually a proverb among the Greeks,

But let us discuss the advantages which our future orator may reasonably expect to derive from the study of Music. Music has two modes of expression in the voice and in the body; [*](Music includes dancing.) for both voice and body require to be controlled by appropriate rules. Aristoxenus divides music, in so far as it concerns the voice, into rhythm and melody, the one consisting in measure, the latter in sound and song. Now I ask you whether it is not absolutely necessary for the orator to be acquainted with all these methods of expression which are concerned firstly with gesture, secondly with the arrangement of words and thirdly with the inflexions of the voice, of which a great variety are required in pleading.

Otherwise we must assume that structure and the euphonious combination of sounds are necessary only for poetry, lyric and otherwise, but superfluous in pleading, or that unlike music, oratory has no interest in the variation of arrangement and sound to suit the demands of the case.

But eloquence does vary both tone and rhythm, expressing sublime thoughts with elevation, pleasing thoughts with sweetness, and ordinary with gentle utterance, and in every expression of its art is in sympathy with the emotions of which it is the mouthpiece.

It is by the raising, lowering or inflexion of the voice that the orator stirs the emotions of his hearers, and the measure, if I may repeat the term, of voice or phrase differs according as we wish to rouse the indignation or the pity of the judge. For, as we know, different emotions are roused even by the various musical instruments, which are incapable of reproducing speech.

Further the

To proceed, an orator will assuredly pay special attention to his voice, and what is so specially the concern of music as this? Here too I must not anticipate a later section of this work, and will content myself by citing the example of Gaius Gracchus, the leading orator of his age, who during his speeches had a musician standing behind him with a pitchpipe, or tonarion as the Greeks call it, whose duty it was to give him the tones in which his voice was to be pitched.

Such was the attention which he paid to this point even in the midst of his most turbulent speeches, when he was terrifying the patrician party and even when he had begun to fear their power. I should like for the benefit of the uninstructed, those

creatures of the heavier Muse,

They will at any rate admit that the poets should be read by our future orator. But can they be read without some knowledge of music? Or if any of my critics be so blind as to have some doubts about other forms of poetry, can the lyric poets at any rate be read without such knowledge? If there were anything novel in my insistence on the study of music, I should have to treat the matter at greater length.

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

For, if necessary, he will use the syllogism, and he will certainly make use of the enthymeme which is a rhetorical form of syllogism. [*]( See v. xiv. I for an example from the Pro Ligario. The cause was then doubtful, as there were arguments on both sides. Now, however, we must regard that cause as the better, to which the gods have given their approval. ) Further the most absolute form of proof is that which is generally known as linear demonstration. And what is the aim of oratory if not proof?

Again oratory sometimes detects falsehoods closely resembling the truth by the use of geometrical methods. An example of this may be found in connexion with numbers in the so-called pseudographs, a favourite amusement in our boyhood. [*](It is not known to what Quintilian refers.) But there are more important points to be considered. Who is there who would not accept the following proposition?

When the lines bounding two figures are equal in length, the areas contained within those lines are equal.

and historians have been taken to task by geometricians for believing the time taken to circumnavigate an island to be a sufficient indication of its size. For the space enclosed is in proportion to the perfection of the figure.
