Analysis of Fragment. Where's The Poet?

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 wonderous 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
Come articulate and presseth
Or his ear like mother-tongue.
