He knew this, he says, by "certain vital signs" discernible in what he had already written. What were those "vital signs," those proofs indubitable to Milton that he had the art and faculty of a poet? We need but refer the reader for the answer to those smaller poetical compositions of Milton, both in English and in Latin, which survive as specimens of his earliest Muse. Of these, some three or four which happen to be specially dated--such as the _Elegy on the Death of a Fair Infant_, written in 1626, or the author's eighteenth year; the well-known _Hymn on the Morning of Christ's Nativity_, written in 1629, when the author was just twenty-one; and the often-quoted _Lines on Shakespeare_, written not much later--may be cited as convenient materials from which anyone who would convince himself minutely of Milton's youthful vocation to poetry, rather than to anything else, may derive proofs on that head. Here will be found power of the most rare and beautiful conception, choice of words the most exact and exquisite, the most perfect music and charm of verse. Above all, here will be found that ineffable something--call it imagination or what we will--wherein lies the intimate and ineradicable peculiarity of the poet: the art to work on and on for ever in a purely ideal element, to chase and marshal airy nothings according to a law totally unlike that of rational association, never hastening to a logical end like the schoolboy when on errand, but still lingering within the wood like the schoolboy during holiday. This peculiar mental habit, nowhere better described than by Milton himself when he speaks of verse "Such as the meeting soul may pierce, In notes with many a winding bout Of linkèd sweetness long drawn out With wanton heed and giddy cunning," is so characteristic of the poetical disposition that, though in most of the greatest poets, as, for example, Dante, Goethe, Shakespeare in his dramas, Chaucer, and almost all the ancient Greek poets, it is not observable in any extraordinary degree, chiefly because in them the element of direct reference to human life and its interests had fitting preponderance, yet it may be affirmed that he who, tolerating or admiring these poets, does not relish also such poetry as that of Spenser, Keats, and Shakespeare in his minor pieces, but complains of it as wearisome and sensuous, is wanting in a portion of the genuine poetic taste.
