...glittering idly in the moon...
...It was an act of stealth
And troubled pleasure; not without the voice
Of mountain-echoes did my Boat move on,
Leaving behind her still on either side
Small circles glittering idly in the moon,
Until they melted all into one track
Of sparkling light....
~ William Wordsworth, from "The Prelude: Book 1: Childhood and School-time"
