For lo! creation's self is one great choir,
And what is Nature's order but the rhyme
Whereto the worlds keep time,
And all things move with all things from their prime?
Who shall expound the mystery of the lyre?
In far retreats of elemental mind
Obscurely comes and goes
The imperative breath of song, that as the wind
Is trackless, and oblivious whence it blows.
--_William Watson_
