And wisely curb'd proud man's pretending wit:
As on the land while here the ocean gains,
In other parts it leaves wide sandy plains;
Thus in the soul while memory prevails,
The solid pow'r of understanding fails;
Where beams of warm imagination play,
The memory's soft figures melt away.
One science only will one genius fit;
So vast is art, so narrow human wit:
Not only bounded to peculiar arts,
But oft in those, confin'd to single parts.
Like kings we lose the conquests gain'd before,
By vain ambition still to make them more;
Each might his sev'ral province well command,
Would all but stoop to what they understand.
First follow NATURE, and your judgment frame
By her just standard, which is still the same:
Unerring Nature, still divinely bright,
One clear, unchang'd, 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 spirits feeds, with vigour fills the whole,
Each motion guides, and ev'ry nerve sustains;
Itself unseen, but in th' effects, remains.
Some, to whom Heav'n 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 winged courser, like a gen'rous horse,
Shows most true mettle when you check his course.
Those RULES of old discover'd, not devis'd,
Are Nature still, but Nature methodis'd;
Nature, like liberty, is but restrain'd
By the same laws which first herself ordain'd.
Hear how learn'd Greece her useful rules indites,
When to repress, and when indulge our flights:
High on Parnassus' top her sons she show'd,
And pointed out those arduous paths they trod;
Held from afar, aloft, th' immortal prize,
And urg'd the rest by equal steps to rise.
Just precepts thus from great examples giv'n,
She drew from them what they deriv'd from Heav'n.
The gen'rous critic fann'd the poet's fire,
And taught the world with reason to admire.
Then criticism the Muse's handmaid prov'd,
To dress her charms, and make her more belov'd;
But following wits from that intention stray'd;
Who could not win the mistress, woo'd the maid;
Against the poets their own arms they turn'd,
Sure to hate most the men from whom they learn'd.
So modern 'pothecaries, taught the art
By doctor's bills to play the doctor's part,
Bold in the practice of mistaken rules,
Prescribe, apply, and call their masters fools.
Some on the leaves of ancient authors prey,
Nor time nor moths e'er spoil'd so much as they:
Some drily plain, without invention's aid,
Write dull receipts how poems may be made:
These leave the sense, their learning to display,
And those explain the meaning quite away.
You then whose judgment the right course would steer,
Know well each ANCIENT'S proper character;
His fable, subject, scope in ev'ry 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 compar'd, his text peruse;
And let your comment be the Mantuan Muse.
