Ye living lamps, by whose dear light
The nightingale does sit so late,
And studying all the summer night,
Her matchless songs does meditate;
Ye county comets, that portend
No war nor prince's funeral,
Shining unto no higher end
Than to presage the grass's fall;
Ye glow-worms, whose officious flame
To wand'ring mowers shows the way,
That in the night have lost their aim,
And after foolish fires do stray;
Your courteous lights in vain you waste,
Since Juliana here is come,
For she my mind hath so displac'd
That I shall never find my home.
Andrew Marvell
