The mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness; this power arises from within...could this influence be durable in its original purity and force, it is impossible to predict the greatness of the result; but when composition begins, inspiration is already on the decline; and the most glorious poetry that has been communicated to the world is probably a feeble shadow of the original conceptions of the poet.
