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.” Mr. Briggs, writing to him on the appearance of the poem in the _Democratic Review_, reminds him that he had read a bit of it when visiting him in his house at Staten Island, and adds: “But I did not anticipate that you could or would lengthen out those few lines into a poem so full of majesty and sweetness. So far as my observation will allow me to judge, it is the best sustained effort of the American Muse. The structure of the verse is exceedingly fine to my ear, although it may not be as acceptable to the public ear as the almost emasculate smoothness of Bryant, to which it has been accustomed. The bold bright images with which ‘Prometheus’ abounds would be sufficient of themselves to give you a name among the wielders of the pen, but the noble and true spirit of Philosophy which they help to develop makes them appear of secondary importance, and gives you a claim to a higher renown than the mere word-mongers of Parnassus can ever aspire to.” Lowell, in replying to this letter, wrote: “My ‘Prometheus’ has not received a single public notice yet, though I have been puffed to repletion for poems without a tithe of its merit. Your letter was the first sympathy I received. Although such great names as Goethe, Byron, and Shelley have all handled the subject in modern times, you will find that I have looked at it from a somewhat new point of view. I have made it _radical_, and I believe that no poet in this age can write much that is good unless he give himself up to this tendency. For radicalism has now for the first time taken a distinctive and acknowledged shape of its own. So much of its spirit as poets in former ages have attained (and from their purer organization they could not fail of some) was by instinct rather than by reason. It has never till now been seen to be one of the two great
