Where's the Poet? show him! show him!
Muses nine! that I may know him!
'Tis the man who with a man
Is an equal, be he King,
Or poorest of the beggar-clan,
Or any other wondrous thing
A man may be 'twixt ape and Plato;
'Tis the man who with a bird,
Wren, or Eagle, finds his way to
All its instincts; he hath heard
The Lion's roaring, and can tell
What his horny throat expresseth,
And to him the Tiger's yell
Comes articulate and presseth
On his ear like mother-tongue.
