After the death of his father, being now more at ease in his circumstances, he gave up taking pupils, and quitted the large house in Barbican for a smaller in High Holborn, opening backwards into Lincoln's-Inn-Fields. This removal was about Michaelmas, 1647.
During this period, 1639—1649, while his interests were engaged by the all-absorbing events of the civil strife, he wrote no poetry, or none deserving the name. All artists have intervals of non-productiveness, usually caused by exhaustion. This was not Milton's case. His genius was not his master, nor could it pass, like that of Leonardo da Vinci, unmoved through the most tragic scenes. He deliberately suspended it at the call of what he believed to be duty to his country. His unrivalled power of expression was placed at the service of a passionate political conviction. This prostitution of faculty avenged itself; for when he did turn to poetry, his strength was gone from him. The period is chiefly marked, by sonnets, not many, one in a year, or thereabouts. That On the religious memory of Mrs. Catherine Thomson, in 1646, is the lowest point touched by Milton in poetry, for his metrical psalms do not deserve the name.
The sonnet, or Elegy on Mrs. Catherine Thomson in the form of a sonnet, though in poetical merit not distinguishable from the average religious verse of the Caroline age, has an interest for the biographer. It breathes a holy calm that is in sharp contrast with the angry virulence of the pamphlets, which were being written at this very time by the same pen. Amid his intemperate denunciations of his political and ecclesiastical foes, it seems that Milton did not inwardly forfeit the peace which passeth all understanding. He had formerly said himself (Doctrine and Disc.), "nothing more than disturbance of mind suspends us from approaching to God." Now, out of all the clamour and the bitterness of the battle of the sects, he can retire and be alone with his heavenly aspirations, which have lost none of their ardour by having laid aside all their sectarianism. His genius has forsaken him, but his soul still glows with the fervour of devotion. And even of this sonnet we may say what Ellis says of Catullus, that Milton never ceases to be a poet, even when his words are most prosaic.
The sonnet (xv.) On the Lord-General Fairfax, at the siege of Colchester, written in 1648, is again a manifesto of the writer's political feelings, nobly uttered, and investing party with a patriotic dignity not unworthy of the man, Milton. It is a hortatory lyric, a trumpet-call to his party in the moment of victory to remember the duties which that victory imposed upon them. It is not without the splendid resonance of the Italian canzone. But it can scarcely be called poetry, expressing, as it does, facts directly, and not indirectly through their imaginative equivalents. Fairfax was, doubtless, well worthy that Milton should have commemorated him in a higher strain. Of Fairfax's eminent qualities the sonnet only dwells on two, his personal valour, which had been tried in many fights—he had been three times dangerously wounded in the Yorkshire campaign—and his superiority to sordid interests. Of his generalship, in which he was second to Cromwell only, and of his love of arts and learning, nothing is said, though the last was the passion of his life, for which at forty he renounced ambition. Perhaps in 1648 Milton, who lived a very retired life, did not know of these tastes, and had not heard that it was by Fairfax's care that the Bodleian library was saved from wreck on the surrender of Oxford in 1646. And it was not till later, years after the sonnet was written, that the same Fairfax, "whose name in arms through Europe rings," became a competitor of Milton in the attempt to paraphrase the Psalms in metre.
Milton's paraphrase of the Psalms belongs to history, but to the history of psalmody, not that of poetry. At St. Paul's School, at fifteen, the boy had turned two psalms, the 114th and the 136th, by way of exercise. That in his day of plenary inspiration, Milton, who disdained Dryden as "a rhymist but no poet," and has recorded his own impatience with the "drawling versifiers," should have undertaken to grind down the noble antistrophic lyrics of the Hebrew bard into ballad rhymes for the use of Puritan worship, would have been impossible. But the idea of being useful to his country had acquired exclusive possession of his mind. Even his faculty of verse should be employed in the good cause. If Parliament had set him the task, doubtless he would have willingly undertaken it, as Corneille, in the blindness of Catholic obedience, versified the Imitatio Christi at the command of the Jesuits. Milton was not officially employed, but voluntarily took up the work. The Puritans were bent upon substituting a new version of the Davidic Psalms for that of Sternhold and Hopkins, for no other reason than that the latter formed part of the hated Book of Common Prayer. The Commons had pronounced in favour of a version by one of their own members, the staunch Puritan M.P. for Truro, Francis Rouse. The Lords favoured a rival book, and numerous other claimants were before the public. Dissatisfied with any of these attempts, Milton would essay himself. In 1648 he turned nine psalms, and recurring to the task in 1653, "did into verse" eight more. He thought these specimens worth preserving, and annexing to the volume of his poems which he published himself in 1673. As this doggerel continues to encumber each succeeding edition of the Poetical Works, it is as well that Milton did not persevere with his experiment and produce a complete Psalter. He prudently abandoned a task in which success is impossible. A metrical psalm, being a compromise between the psalm and the hymn, like other compromises, misses, rather than combines, the distinctive excellences of the things united. That Milton should ever have attempted what poetry forbids, is only another proof how entirely at this period more absorbing motives had possession of his mind, and overbore his poetical judgment. It is a coincidence worth remembering that Milton's contemporary, Lord Clarendon, was at this very time solacing his exile at Madrid by composing, not a version but a commentary upon the Psalms, "applying those devotions to the troubles of this time."
Yet all the while that he was thus unfaithful in practice to his art, it was poetry that possessed his real affections, and the reputation of a poet which formed his ambition. It was a temporary separation, and not a divorce, which he designed. In each successive pamphlet he reiterates his undertaking to redeem his pledge of a great work, as soon as liberty shall be consolidated in the realm. Meanwhile, as an earnest of what should be hereafter, he permitted the publication of a collection of his early poems.
This little volume of some 200 pages, rude in execution as it is, ranks among the highest prizes of the book collector, very few copies being extant, and those mostly in public libraries. It appeared in 1645, and owed its appearance, not to the vanity of the author, but to the zeal of a publisher. Humphrey Moseley, at the sign, of the Prince's Arms, in St. Paul's Churchyard, suggested the collection to Milton, and undertook the risk of it, though knowing, as he says in the prefixed address of The Stationer to the Reader, that "the slightest pamphlet is nowadays more vendible than the works of learnedest men." It may create some surprise that, in 1645, there should have been any public in England for a volume of verse. Naseby had been fought in June, Philiphaugh in September, Fairfax and Cromwell were continuing their victorious career in the west, Chester, Worcester, and the stronghold of Oxford, alone holding out for the King. It was clear that the conflict was decided in favour of the Parliament, but men's minds must have been strung to a pitch of intense expectation as to what kind of settlement was to come. Yet, at the very crisis of the civil strife, we find a London publisher able to bring out the Poems of Waller (1644), and sufficiently encouraged by their reception to follow them up, in the next year, with the Poems of Mr. John Milton. Are we warranted in inferring that a finer public was beginning to loathe the dreary theological polemic of which it had had a surfeit, and turned to a book of poetry as that which was most unlike the daily garbage, just as a later public absorbed five thousand copies of Scott's Lay of the Last Minstrel in the year of Austerlitz? One would like to know who were the purchasers of Milton and Waller, when the cavalier families were being ruined by confiscations and compositions, and Puritan families would turn with pious horror from the very name of a Mask.
Milton was himself editor of his own volume, and prefixed to it, again out of Virgil's Eclogues, the characteristic motto, "Baccare frontem Cingite, ne vati noceat mala lingua futuro," indicating that his poetry was all to come.
