In 1845 appeared "The Vision of Sir Launfal,"—a genuine inspiration composed in two days in a sort of ecstasy of poetic fervor. That more than anything established his fame. He recognized that he was dedicated to the Muses.

In 1846 he wrote:—

"If I have any vocation, it is the making of verse. When I take my pen for that, the world opens itself ungrudgingly before me; everything seems clear and easy, as it seems sinking to the bottom could be as one leans over the edge of his boat in one of those dear coves at Fresh Pond.... My true place is to serve the cause as a poet. Then my heart leaps before me into the conflict."

The same year he began his "Biglow Papers" in the Boston Courier. Such jeux d'esprit are apt to be ephemeral. Lowell's are immortal. They preserved in literary form a fast-fading dialect; they caught and embalmed the mighty issues of a tremendous world-problem. Their influence was incalculable. He gathered them into a volume in 1848, and became corresponding editor of the Anti-Slavery Standard. Fortunate man who throws himself into an unpopular cause which is in harmony with the Right! How different from Wordsworth who attacked the ballot and took sides against reform!

Lowell's penchant for satire was exemplified again the same year in his "Fable for Critics."

In this Lowell with no sparing hand laid on his portraits most droll and amusing colors. It is a comic portrait gallery, a series of caricatures whose greatest value (as in all good caricatures) lies in the accurate presentation of characteristic features. He did not spare himself:—

"There is Lowell, who's striving Parnassus to climb
With a whole bale of isms tied together with rhyme.
He might get on alone, spite of troubles and bowlders,
But he can't with that bundle he has on his shoulders.
The top of the hill he will ne'er come nigh reaching
Till he learns the distinctions 'twixt singing and preaching;
His lyre has some chords that would ring pretty well,
But he'd rather by half make a drum of the shell,
And rattle away till he's old as Methusalem
At the head of a march to the last New Jerusalem."

Some of his thrusts left embittered feelings, but in general the tone was so good-natured that only the thin-skinned could object, and it must be confessed many of his judgments have been confirmed by Time.

In 1851 Lowell visited Europe, and spent upwards of a year widening his acquaintance with the polite languages. But it is remarkable that Lowell gave the world almost no metrical translations. Shortly after his return his wife died (Oct. 27, 1853) after a slow decline. In reference to this bereavement Longfellow wrote his beautiful poem, "The Two Angels."

The following year Longfellow resigned the Smith Professorship of the French and Spanish Languages and Literature and Belles Lettres, and Lowell was appointed his successor with two years' leave of absence. He had won his spurs. He had collected his poems in two volumes, not including "A Year's Life," the "Biglow Papers," or the "Fable for Critics." He was known as one of the most brilliant contributors to Putnam's Monthly and other magazines.
