With aspirations thus vast, though unformed, with "amplitude of mind to greatest deeds," Milton retired to his father's house in the country. Five more years of self-education, added to the seven years of academical residence, were not too much for the meditation of projects such as Milton was already conceiving. Years many more than twelve, filled with great events and distracting interests, were to pass over before the body and shape of _Paradise Lost_ was given to these imaginings. The country retirement in which the elder Milton had fixed himself was the little village of Horton, situated in that southernmost angle of the county of Buckingham, which insinuates itself between Berks and Middlesex. Though London was only about seventeen miles distant, it was the London of Charles I., with its population of some 300,000 only; before coaches and macadamised roads; while the Colne, which flows through the village, was still a river, and not the kennel of a paper-mill. There was no lack of water and woods meadow and pasture, closes and open field, with the regal towers of Windsor--"bosom'd high in tufted trees," to crown the landscape. Unbroken leisure, solitude, tranquillity of mind, surrounded by the thickets and woods, which Pliny thought indispensable to poetical meditation (Epist.9.10), no poet's career was ever commenced under more favourable auspices. The youth of Milton stands in strong contrast with the misery, turmoil, chance medley, struggle with poverty, or abandonment to dissipation, which blighted the early years of so many of our men of letters. Milton's life is a drama in three acts. The first discovers him in the calm and peaceful retirement of Horton, of which _L'Allegro_, _Il Penseroso_, and _Lycidas_ are the expression. In the second act he is breathing the foul and heated atmosphere of party passion and religious hate, generating the lurid fires which glare in the battailous canticles of his prose pamphlets. The three great poems, _Paradise Lost_, _Paradise Regained_, and _Samson Agonistes_, are the utterance of his final period of solitary and Promethean grandeur, when, blind, destitute, friendless, he testified of righteousness, temperance, and judgment to come, alone before a fallen world. In this delicious retirement of Horton, in alternate communing with nature and with books, for five years of persevering study he laid in a stock, not of learning, but of what is far above learning, of wide and accurate knowledge. Of the man whose profession is learning, it is characteristic that knowledge is its own end, and research its own reward. To Milton all knowledge, all life, virtue itself, was already only a means to a further end. He will know only "that which is of use to know," and by useful, he meant that which conduced to form him for his vocation of poet.
