Percy Bysshe Shelley: Fragment: 'Wake the Serpent Not'

Wake the serpent not—lest he
Should not know the way to go,—
Let him crawl which yet lies sleeping
Through the deep grass of the meadow!
Not a bee shall hear him creeping,
Not a may-fly shall awaken
From its cradling blue-bell shaken,
Not the starlight as he's sliding
Through the grass with silent gliding.
