Mr. Briggs, who was the stanchest of Lowell’s literary friends at this time, wrote with enthusiasm of the volume, using terms of admiration which must have been grateful indeed, since they were charged with discrimination and just appreciation; but he was frank and honest in his friendly judgment, and he wrote to Lowell of “A Legend of Brittany:” “It is too warm, rich, and full of sweet sounds and sights; the incense overpowers me, and the love and crime, and prayers and monks and glimpses of spirits oppress me. I am too much a clod of earth to mingle well in such elements. I feel while reading it as though I were lying upon a bed of down with a canopy of rose-colored silk above me, with gleams of sunshine darting in the room and half revealing and at times more than revealing strange figures painted upon the walls of my chamber. But I do not wonder that M. W. should like it. It is the proper reading for pure-minded loving creatures, from whose eyes knowledge with its hard besom has not yet swept away the golden cobwebs of fancy. I like her the better myself for liking it.”[38]

This long poem is not the only one in the book which springs from pure delight in poetic imagination; but it is by far the most full and unalloyed expression of this pleasure. When one reads, however, such a poem as “Rhœcus,” with its preface apologizing for so much paganism, and its application, and especially when one reads “Prometheus,” one is aware how largely Lowell was dominated, even in this time when his soul was flushed with the sense of beauty and awake to the tendrils it was putting forth, by a strong purpose to read the lesson of beauty and love to his fellows. The seriousness of life was indeed charged with an exalted meaning by the revelation which came to him when he was admitted into the intimate companionship of a woman who had in her something of the spirit of a prophetess, but it would be untrue to say that Maria White handed him the torch; she kindled to a greater brilliancy that which he already held, and his love transmuted the vague stirrings of his own nature into more definite purpose. Keats, to refer again to one with whom Lowell certainly had spiritual kinship, was mildly affected somewhat in the same way by the friendship which he formed in his impressionable years with Hunt and his circle, and if we could imagine Fanny Brawne a Mary Wollstonecraft, we might speculate on the effect she would have had on his poetry. Even Keats, with his passionate devotion to beauty, could dig a subterranean passage under the opening of the third book of “Endymion” for the purpose of blowing up the “present ministers;” and Lowell, taking the world-worn myth of Prometheus, could write into it reflections apposite to what he regarded as a tremendous upheaving force just ready to manifest itself in society. The poem of “Prometheus,” however, justly stands high in the estimation of Lowell’s readers, for the thought involved in it rises above the level of a didactic utterance, and carries with it an impersonation of human dignity which saves it from the reproach of making the myth a mere text for a modern discourse. The poem is the most comprehensive and largest expression of the mind of the poet at this period of emancipation, and the fine images with which it abounds spring from the subject itself and are not mere decorations.

Here, again, a comparison of “Prometheus” with Keats’s “Hyperion” illustrates the infusion of moral ardor which separates the disciple from the master. Keats summed up his poetic philosophy in the lines—

“For ’tis the eternal law
That first in beauty should be first in might,”—

and he was fain to see the operation of Nature’s law by which one race of conquerors would dispossess another.

“So on our heels a fresh perfection treads.”

Lowell, speculating on the eternal struggle, figured in “Prometheus,” of right and wrong, of darkness and light, bids Jove heed that he—

“And all strength shall crumble except love”—

and sees in a vision—

“Peaceful commonwealths where sunburnt Toil
Reaps for itself the rich earth made its own.”
