before his successful and perfidious adversary.  The only imaginary being resembling in any degree Prometheus, is Satan; and Prometheus is, in my judgement, a more poetical character than Satan, because, in addition to courage, and majesty, and firm and patient opposition to omnipotent force, he is susceptible of being described as exempt from the taints of ambition, envy, revenge, and a desire for personal aggrandisement, which, in the Hero of “Paradise Lost”, interfere with the interest.  The character of Satan engenders in the mind a pernicious casuistry which leads us to weigh his faults with his wrongs, and to excuse the former because the latter exceed all measure.  In the minds of those who consider that magnificent fiction with a religious feeling it engenders something worse.  But Prometheus is, as it were, the type of the highest perfection of moral and intellectual nature, impelled by the purest and the truest motives to the best and noblest ends.

This Poem was chiefly written upon the mountainous ruins of the Baths of Caracalla, among the flowery glades, and thickets of odoriferous blossoming trees, which are extended in ever winding labyrinths upon its immense platforms and dizzy arches suspended in the air.  The bright blue sky of Rome, and the effect of the vigorous awakening spring in that divinest climate, and the new life with which it drenches the spirits even to intoxication, were the inspiration of this drama.

The imagery which I have employed will be found, in many instances, to have been drawn from the operations of the human mind, or from those external actions by which they are expressed.  This is unusual in modern poetry, although Dante and Shakespeare are full of instances of the same kind:  Dante indeed more than any other poet, and with greater success.  But the Greek poets, as writers to whom no resource of awakening the sympathy of their contemporaries was unknown, were in the habitual use of this power; and it is the study of their works (since a higher merit would probably be denied me) to which I am willing that my readers should impute this singularity.

One word is due in candour to the degree in which the study of contemporary writings may have tinged my composition, for such has been a topic of censure with regard to poems far more popular, and indeed more deservedly popular, than mine.  It is impossible that any one who inhabits the same age with such writers as those who stand in the foremost ranks of our own, can conscientiously assure himself that his language and tone of thought may not have been modified by the study of the productions of those extraordinary intellects.  It is true, that, not the spirit of their genius, but the forms in which it has manifested itself, are due less to the peculiarities of their own minds than to the peculiarity of the moral and intellectual condition of the minds among which they have been produced.  Thus a number of writers possess the form, whilst they want the spirit of those whom, it is alleged, they imitate; because the former is the endowment of the age in which they live, and the latter must be the uncommunicated lightning of their own mind.
