Now that these wings to speed my wish ascend, The more I feel vast air beneath my feet, The more toward boundless air on pinions fleet, Spurning the earth, soaring to heaven, I tend: Nor makes them stoop their flight the direful end Of Daedal's son; but upward still they beat: What life the while with my life can compete, Though dead to earth at last I shall descend?

Long-look'd for day's sun, when wilt thou ascend? Let not this thieve friend, misty veil of night, Encroach on day, and shadow thy fair light, Whilst thou com'st tardy from thy Thetis' bed, Blushing forth golden hair and glorious red; O, stay not long, bright lanthorn of the day, To light my miss'd-way feet to my right way!
