One can see, looking backward, that Tennyson's genius flowered in due season; there had been a plentiful harvest of verse in the preceding generation, but it had been garnered, and the field was clear. The hour had come for a new writer to take up the succession to that brilliant and illustrious group who, in the first quarter of the last century, raised English poetry to a height far above the classic level of the age before them. Three leaders of that band--Byron, Keats, and Shelley--died young; the sum total of their years added together exceeds by no more than a decade the space of Tennyson's single life. And if the creative period of a poet's life may be reckoned as beginning at twenty-one (which is full early), it sums up to no more than thirty-one years for all the three poets whom we have named, and to sixty years for Tennyson alone. When his first volume appeared (1832), Byron, Shelley, and Keats were dead; Scott and Coleridge had long ceased to write poetry, and were dying; Wordsworth, who had done all his best work long before, alone survived, for Southey cannot be counted in the same rank. Moreover, England may be said to have been just then passing through one of those periods of artistic depression that precede a revival; the popular taste was artificial and decadent, it was running down to the pseudo-romantic and false Gothic, to the conventional Keepsake note in sentiment, to extravagant admiration of such poems as Moore's _Lalla Rookh_. The purchase by the State of the Elgin Marbles, and the opening of the National Gallery, had prepared the way for better things in art; but I may affirm, speaking broadly, that it was a flat interval, when the new generation was just looking for some one to give form to an upward movement of ideas.
