Milton alludes to the fact that the constellation of the Bear never sets, when he says,

"Let my lamp at midnight hour
Be seen in some high lonely tower,
Where I may oft outwatch the Bear."
Il Penseroso

And Prometheus, in James Russell Lowell's poem, says,

"One after one the stars have risen and set,
Sparkling upon the hoar-frost of my chain;
The Bear that prowled all night about the fold
Of the North Star, hath shrunk into his den,
Scared by the blithsome footsteps of the dawn."

The last star in the tail of the Little Bear is the Pole star, called also the Cynosure. Milton says,

"Straight mine eye hath caught new pleasures
While the landscape round it measures.
* * * * * * * *
Towers and battlements it sees
Bosomed high in tufted trees,
Where perhaps some beauty lies
The Cynosure of neighboring eyes."
L'Allegro.

The reference here is both to the Pole-star as the guide of mariners, and to the magnetic attraction of the North. He calls it also the "Star of Aready," because Callisto's boy was named Arcas, and they lived in Arcadia. In Milton's Comus, the elder brother, benighted in the woods, says,

"Some gentle taper!
Through a rush candle, from
the wicker hole
Of some clay habitation,
visit us
With thy long levelled rule
of streaming light,
And thou shalt be our star of Aready,
Or Tyrian Chynsure."
