Sweet Summer! unto you this swallow drew, By secret instincts inappeasable, That did direct him well, Lured from his gelid North which wrought him wrong, Wintered of sunning song;— By happy instincts inappeasable, Ah yes! that led him well, Lured to the untried regions and the new Climes of auspicious you; To twitter there, and in his singing dwell. But ah! if you, my Summer, should grow waste, With grieving skies o’ercast, For such migration my poor wing was strong But once; it has no power to fare again Forth o’er the heads of men, Nor other Summers for its Sanctuary: But from your mind’s chilled sky It needs must drop, and lie with stiffened wings Among your soul’s forlornest things; A speck upon your memory, alack! A dead fly in a dusty window-crack. O therefore you who are What words, being to such mysteries As raiment to the body is, Should rather hide than tell; Chaste and intelligential love: Whose form is as a grove Hushed with the cooing of an unseen dove; Whose spirit to my touch thrills purer far Than is the tingling of a silver bell; Whose body other ladies well might bear As soul,—yea, which it profanation were For all but you to take as fleshly woof, Being spirit truest proof; Whose spirit sure is lineal to that Which sang _Magnificat_: Chastest, since such you are, Take this curbed spirit of mine, Which your own eyes invest with light divine, For lofty love and high auxiliar In daily exalt emprise Which outsoars mortal eyes; This soul which on your soul is laid, As maid’s breast against breast of maid; Beholding how your own I have engraved On it, and with what purging thoughts have laved This love of mine from all mortality Indeed the copy is a painful one, And with long labour done! O if you doubt the thing you are, lady, Come then, and look in me; Your beauty, Dian, dress and contemplate Within a pool to Dian consecrate! Unveil this spirit, lady, when you will, For unto all but you ’tis veilèd still: Unveil, and fearless gaze there, you alone, And if you love the image—’tis your own! IV. A CARRIER SONG. I. SINCE you have waned from us, Fairest of women! I am a darkened cage Song cannot hymn in. My songs have followed you, Like birds the summer; Ah! bring them back to me, Swiftly, dear comer! _Seraphim_, _Her to hymn_, _Might leave their portals_; _And at my feet learn_ _The harping of mortals_!
