We do this either because it is necessary or to make our meaning clearer or, as I have already said, to produce a decorative effect. When it secures none of these results, our metaphor will be out of place. As an example of a necessary metaphor I may quote the following usages in vogue with peasants when they call a vinebud gemma, a gem (what other term is there which they could use?), or speak of the crops being thirsty or the fruit suffering. For the same reason we speak of a hard or rough man, there being no literal term for these temperaments.

On the other hand, when we say that a man is kindled to anger or on fire with greed or that he has fallen into

v7-9 p.305
error, we do so to enhance our meaning. For none of these things can be more literally described in its own words than in those which we import from elsewhere. But it is a purely ornamental metaphor when we speak of brilliance of style, splendour of birth, tempestuous public assemblies, thunderbolts of eloquence, to which I may add the phrase employed by Cicero [*](Pro Mil. xiii. 34, 35. ) in his defence of Milo where he speaks of Clodius as the fountain, and in another place as the fertile field and material of his client's glory.

It is even possible to express facts of a somewhat unseemly character by a judicious use of metaphor, as in the following passage: [*]( Virg. Georg. iii. 1 )

  1. This do they lest too much indulgence make
  2. The field of generation slothful grow
  3. And choke its idle furrows.
On the whole metaphor is a shorter form of simile, while there is this further difference, that in the latter we compare some object to the thing which we wish to describe, whereas in the former this object is actually substituted for the thing.

It is a comparison when I say that a man did something like a lion, it is a metaphor when I say of him, He is a lion. Metaphors fall into four classes. In the first we substitute one living thing for another, as in the passage where the poet, speaking of a charioteer, [*](Probably from Ennius.) says,

  1. The steersman then
  2. With mighty effort wrenched his charger round.
or when Livy [*](Liv. XXXVIII. liv.) says that Scipio was continually barked at by Cato.

Secondly, inanimate things may be substituted for inanimate, as in the Virgilian.

  1. And gave his fleet the rein,
Aen. vi. 1.
v7-9 p.307
or inanimate may be substituted for animate, as in
  1. Did the Argive bulwark fall by sword or fate?
From an unknown tragedian.
or animate for inanimate, as in the following lines:
  1. The shepherd sits unknowing on the height
  2. Listening the roar from some far mountain brow.
Aen. ii. 307.

But, above all, effects of extraordinary sublimity are produced when the theme is exalted by a bold and almost hazardous metaphor and inanimate objects are given life and action, as in the phrase

  1. Araxes' flood that scorns a bridge,
Aen. viii. 728.
or in the passage of Cicero, [*](Pro Lit. iii. 9. See VIII. iv. 27. ) already quoted,

where he cries,

What was that sword of yours doing, Tubero, the sword you drew on the field of Pharsalus? Against whose body did you aim its point? What meant those arms you bore?
Sometimes the effect is doubled, as in Virgil's.
  1. And with venom arm the steel.
Aen. ix. 773.
For both
to arm the steel
and
to arm with venom
are metaphors.

These four kinds of metaphor are further subdivided into a number of species, such as transference from rational beings to rational and from irrational to irrational and the reverse, in which the method is the same, and finally from the whole to its parts and from the parts to the whole. But I am not now teaching boys: my readers are old enough to discover the species for themselves when once they have been given the genus.

While a temperate and timely use of metaphor is

v7-9 p.309
a real adornment to style, on the other hand, its frequent use serves merely to obscure our language and weary our audience, while if we introduce them in one continuous series, our language will become allegorical and enigmatic. There are also certain metaphors which fail from meanness, such as that of which I spoke above [*](See VIII. iii. 48.) :
  1. There is a rocky wart upon the mountain's
  2. brow.
or they may even be coarse. For it does not follow that because Cicero was perfectly justified in talking of
the sink of the state,
[*]( In Cat. I. v. 12. ) when he desired to indicate the foulness of certain men, we can approve the following passage from an ancient orator:
You have lanced the boils of the state.

Indeed Cicero [*](De Or. iii. xli. 164. ) himself has demonstrated in the most admirable manner how important it is to avoid grossness in metaphor, such as is revealed by the following examples, which he quotes:—

The state was gelded by the death of Africanus,
or
Glaucia, the excrement of the senate-house.

He also points out that a metaphor must not be too great for its subject or, as is more frequently the case, too little, and that it must not be inappropriate. Anyone who realises that these are faults, will be able to detect instances of them only too frequently. But excess in the use of metaphor is also a fault, more especially if they are of the same species.

Metaphors may also be harsh, that is, far-fetched, as in phrases like

the snows of the head
or
  1. Jove with white snow the wintry Alps bespewed.
From Furius, an old epic poet of the second century (not Furius Bibaculus), cp. Hor. S. ii. v. 11.
v7-9 p.311
The worst errors of all, however, originate in the fact that some authors regard it as permissible to use even in prose any metaphors that are allowed to poets, in spite of the fact that tile latter aim solely at pleasing their readers and are compelled in many cases to employ metaphor by sheer metrical necessity.

For my own part I should not regard a phrase like

the shepherd of the people
as admissible in pleading, although it has the authority of Homer, nor would I venture to say that winged creatures
swim through the air,
despite the fact that this metaphor has been most effectively employed by Virgil to describe the flight of bees and of Daedalus.1 For metaphor should always either occupy a place already vacant, or if it fills the room of something else, should be more impressive than that which it displaces.
