No More Learning

What my amaze, when first I fully learn'd
The wondrous change upon my person done,
And saw my thin hairs to those green leaves turn'd
(Whence yet for them a crown I might have won);
My feet           I stood, and moved, and run--
Thus to the soul the subject members bow--
Become two roots upon the shore, not now
Of fabled Peneus, but a stream as proud,
And stiffen'd to a branch my either arm!
