Having examined the nature of this figure, and the principle on which it is erected; I proceed, as in the first section, to some rules by which it ought to be governed. And in the first place, it is a capital fault to introduce an hyperbole in the description of an ordinary object or event which creates no surprise. In such a case, the hyperbole is altogether unnatural, being destitute of surprise, the only foundation that can support it. Take the following instance, where the subject is extremely familiar, viz. swimming to gain the shore after a shipwreck.

I saw him beat the surges under him,
And ride upon their backs; he trode the water;
Whose enmity he flung aside, and breasted
The surge most swoln that met him: his bold head
’Bove the contentious waves he kept, and oar’d
Himself with his good arms, in lusty strokes
To th’ shore, that o’er his wave-born basis bow’d,
As stooping to relieve him.
Tempest, act 2. sc. 1.

In the next place, it may be gathered from what is said, that an hyperbole can never suit the tone of any dispiriting passion. Sorrow in particular will never prompt such a figure; and for that reason the following hyperboles must be condemned as unnatural.

K. Rich. Aumerle, thou weep’st, my tender-hearted cousin!
We’ll make foul weather with despised tears;
Our sighs, and they, shall lodge the summer-corn,
And make a dearth in this revolting land.
Richard II. Act 3. Sc. 6.

Draw them to Tyber’s bank, and weep your tears
Into the channel, till the lowest stream
Do kiss the most exalted shores of all.
Julius Cæsar, act 1. sc. 1.

Thirdly, a writer, if he wish to succeed, ought always to have the reader in his eye. He ought in particular never to venture a bold thought or expression, till the reader be warmed and prepared for it. For this reason, an hyperbole in the beginning of any work can never be in its place. Example:

Jam pauca aratro jugera regiæ
Moles relinquent.
Horat. Carm. lib. 2. ode. 15.

In the fourth place, the nicest point of all, is to ascertain the natural limits of an hyperbole, beyond which being overstrained it has a bad effect. Longinus, in the above-cited chapter, with great propriety of thought, enters a caveat against an hyperbole of this kind. He compares it to a bowstring, which relaxes by overstraining, and produceth an effect directly opposite to what is intended. I pretend not to ascertain any precise boundary: the attempt would be difficult, if not impracticable. I must therefore be satisfied with an humbler task, which is, to give a specimen of what I reckon overstrained hyperboles; and I shall be also extremely curt upon this subject, because examples are to be found every where. No fault is more common among writers of inferior rank; and instances are found even among those of the finest taste; witness the following hyperbole, too bold even for an Hotspur.

Hotspur talking of Mortimer:

In single opposition hand to hand,
He did confound the best part of an hour
In changing hardiment with great Glendower.
Three times they breath’d, and three times did they drink,
Upon agreement, of swift Severn’s flood;
Who then affrighted with their bloody looks,
Ran fearfully among the trembling reeds,
And hid his crisp’d head in the hollow bank
Blood-stained with these valiant combatants.
First Part Henry IV. act 1. sc. 4.
