But you who seek to give and merit fame
And justly bear a critic's noble name,
Be sure yourself and your own reach to know,
How far your genius, taste, and learning go;
Launch not beyond your depth, but be discreet,
And mark that point where sense and dulness meet.

* * * * *

First follow Nature, and your judgment frame
By her just standard, which is still the same:
Unerring Nature, still divinely bright,
One clear, unchanged, and universal light,
Life, force, and beauty, must to all impart,
At once the source, and end, and test of art.
Art from that fund each just supply provides,
Works without show, and without pomp presides:
In some fair body thus th' informing soul
With spirit feeds, with vigour fills the whole.
Each motion guides, and every nerve sustains;
Itself unseen, but in th' effects, remains.
Some, to whom Heaven in wit has been profuse,
Want as much more, to turn it to its use;
For wit and judgment often are at strife,
Though meant each other's aid, like man and wife.
'Tis more to guide than spur the Muse's steed;
Restrain his fury, than provoke his speed;
The wingèd courser, like a generous horse,
Shows most true mettle when you check his course.

Those rules of old discovered, not devised,
Are Nature still, but Nature methodized;
Nature, like liberty, is but restrained
By the same laws which first herself ordained.

You, then, whose judgment the right course would steer,
Know well each ancient's proper character;
His fable, subject, scope in every page;
Religion, country, genius of his age:
Without all these at once before your eyes,
Cavil you may, but never criticise,
Be Homer's works your study and delight,
Read them by day, and meditate by night;
Thence form your judgment, thence your maxims bring,
And trace the Muses upward to their spring.
Still with itself compared, his text peruse;
And let your comment be the Mantuan Muse.

When first young Maro in his boundless mind
A work t' outlast immortal Rome designed,
Perhaps he seemed above the critic's law,
And but from nature's fountains scorned to draw:
But when t' examine every part he came,
Nature and Homer were, he found, the same.
Convinced, amazed, he checks the bold design;
And rules as strict his laboured work confine
As if the Stagirite o'erlooked each line.
Learn hence for ancient rules a just esteem;
To copy nature is to copy them.

Some beauties yet no precepts can declare,
For there's a happiness as well as care.
Music resembles poetry, in each
Are nameless graces which no methods teach,
And which a master-hand alone can reach.
If, where the rules not far enough extend,
(Since rules were made but to promote their end)
Some lucky license answer to the full
Th' intent proposed, that license is a rule.
Thus Pegasus, a nearer way to take,
May boldly deviate from the common track;
From vulgar bounds with brave disorder part,
And snatch a grace beyond the reach of art,
Which without passing through the judgment, gains
The heart, and all its end at once attains.
In prospects thus, some objects please our eyes,
Which out of nature's common order rise,
The shapeless rock, or hanging precipice.
Great wits sometimes may gloriously offend,
And rise to faults true critics dare not mend.
But tho' the ancients thus their rules invade,
(As kings dispense with laws themselves have made)
Moderns, beware! or if you must offend
Against the precept, ne'er transgress its end;
Let it be seldom and compelled by need;
And have, at least, their precedent to plead.
The critic else proceeds without remorse,
Seizes your fame, and puts his laws in force.

I know there are, to whose presumptuous thoughts
Those freer beauties, e'en in them, seem faults.
Some figures monstrous and misshaped appear,
Considered singly, or beheld too near,
Which, but proportioned to their light or place,
Due distance reconciles to form and grace.
A prudent chief not always must display
His powers in equal ranks, and fair array,
But with th' occasion and the place comply,
Conceal his force, nay, seem sometimes to fly.
Those oft are stratagems which errors seem,
Nor is it Homer nods, but we that dream.
