" Of these am I, who thy protection claim, A watchful sprite, and Ariel is my name.
Late, as I rang'd the crystal wilds of air,
In the clear mirror of thy ruling star
I saw, alas! some dread event impend,
Ere to the main this morning sun descend,
But Heav'n reveals not what, or how, or where: Warn'd by the Sylph, oh pious maid, beware! "

― Alexander Pope , The Rape of the Lock
