Art from that fund each just supply provides,
Works without show, and without pomp presides: 75
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, 80
Want as much more, to turn it to its use;
For wit and judgment often are at strife,
Tho' meant each other's aid, like man and wife.
'T is more to guide, than spur the Muse's steed;
Restrain his fury, than provoke his speed; 85
The winged courser, like a gen'rous horse,
Shows most true mettle when you check his course.

Those RULES of old discovered, not devis'd,
Are Nature still, but Nature methodiz'd;
Nature, like liberty, is but restrain'd 90
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; 95
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, 100
And taught the world with reason to admire.
