Wake the serpent not—lest he <br />Should not know the way to go,-- <br />Let him crawl which yet lies sleeping <br />Through the deep grass of the meadow! <br />Not a bee shall hear him creeping, <br />Not a may-fly shall awaken <br />From its cradling blue-bell shaken, <br />Not the starlight as he’s sliding <br />Through the grass with silent gliding.<br /><br />Percy Bysshe Shelley<br /><br />http://www.poemhunter.com/poem/wake-the-serpent-not/
