The curfew bell was a bell rung in the evening in Medieval England as a curfew signal.^{[1][2][3][4][5][6] [7][8][9][10][11]}

The custom of ringing the curfew bell continued in many British towns and cities, especially in the north of England, well into the 19th century, although by then it had ceased to have any legal status.^[12] The tradition is still practiced in the town of Sandwich, Kent, where a curfew bell known as the "Pig Bell" at St Peter's Church is rung at 8 pm every evening for ten minutes.^[13] At Ruthin in Denbighshire, the custom lapsed in the 1970s but was revived in 2020 after the bells of St Peter's Church were restored.^[14]

At Penrith, Cumbria in the 19th century, the curfew was known as the "Taggy Bell", thought to be derived from the Old Norse tœkke, "to cover".^[12]

The tyranny of William I is described by the poet Francis Thompson,

The shiv'ring wretches, at the curfew sound,
Dejected sunk into their sordid beds,
And, through the mournful gloom of ancient times,
Mus'd sad, or dreamt of better.

Chaucer writes on the curfew bell as just as a time, not a law:

The dede slepe, for every besinesse,
Fell on this carpenter, right as I gesse,
About curfew time, or litel more.

Shakespeare had unusual times for the curfew bell. In Romeo and Juliet, iv 4, he has Lord Capulet saying:

Come, stir, stir, stir, the second coch hath crow'd,
The curfew bell hath rung, tis three o'clock.

In Tempest, v. 1, Prospero says:

You, whose pastime'
Is to make midnight mushrooms, that rejoice
To hear the solemn curfew.

In King Lear, iii. 4, Edgar speaks,

This is the foul fiend, Flibbertigibbet: he begins at curfew
and walks to the first clock.

In the sixteenth century Bishop Joseph Hall's "Fourth Satire" it reads:

Who ever gives a paire of velvet shooes
To th' Holy Rood, or liberally allowes,
But a new rope to ring the couvre-few bell,
But he desires that his great deed may dwell,
Or graven in the chancel window glasse,
Or in his lasting tombe of plated brasse.

In the play The Merry Devil of Edmonton (published 1608), the curfew was at nine o'clock in the evening:

Well, 'tis nine a clocke, 'tis time to ring curfew

John Milton's put in his allegorical Il Penseroso's mouth the words:

Oft on a plat of rising ground,
I hear the far-off curfew sound,
Over some wide-water'd shore,
Swinging slow, with sullen roar...

In Handel's L'Allegro, il Penseroso ed il Moderato these words are accompanied by a pizzicato bass-line, representing a distant bell sound.

The most famous mention of the curfew in English poetry is in Thomas Gray's Elegy Written in a Country Churchyard (1750), whose opening lines are:

The curfew tolls the knell of parting day,
         The lowing herd wind slowly o'er the lea,
The ploughman homeward plods his weary way,
         And leaves the world to darkness and to me

T. S. Eliot Gus the theater cat ("Old possum's book of practical cats")

When the curfew was rung, then I swung on the bell!

Eleanor Farjeon and Herbert Farjeon, William I – 1066 in Kings and Queens (1932). These poems were used to teach history to generations of British schoolchildren:

So William decided these rebels to quell
By ringing a curfew – a sort of a bell
And if any Saxon was found out of bed
After eight o'clock sharp it was "Off with his head!"
