§ 3. Isabella; Letters
Great as is the advance of Isabella upon Endymion, it must still be reckoned among his immature works, in view of the wonderful creations of the following autumn and spring. The six months which followed were a time of immensely rapid growth, not merely in imaginative power and technical mastery, but in intellectual range and vigour, and in moral grip. The not very precocious boy of eighteen and twenty is on the verge of the truly marvellous manhood of his twenty-fourth year, and the man, as well as the genius, is awake. His letters, after The Prelude the most precious document we possess of the growth of a poet’s mind, are especially illuminating for the year 1818. “To enjoy the things that others understand” might have satisfied his aspiration in 1817; in April, 1818, he turns away dissatisfied from his own “exquisite sense of the luxurious,” and feels the need of “philosophy,” bracing experience and activity for his fellow-men. He will learn Greek and Italian,
He had, indeed, “great allies”; Shakespeare and Wordsworth co-operated in deepening and enlarging the scope of his genius; to its richness they could not add. All through 1817, Shakespeare had been a companion; Endymion is strewn with his diction; in April, 1818 (sonnet On sitting down to read King Lear once again), the golden harmonies of romance seemed thin and poor beside the passion and the heights and depths of Shakespearean tragedy. He was already past Endymion, and knew it, as his contemporary preface attests. And Wordsworth led him, by other, not less enthralling or less enduring, paths, to the same deeper understanding of sorrow. He was never weary, Brown tells us, of repeating the Immortality ode; its sublime portrayal of a mind redeemed by discipline and suffering and “an eye that hath kept watch o’er man’s mortality” perhaps contributed to the doctrine of the world as a “Vale of Soul-making” through pain and trouble, which he unfolds in his beautiful letter of April, 1819, to his brother George.
