It faded on the crowing of the cock.
Some say that ever ‘gainst that season comes
Wherein our Saviour’s birth is celebrated,
The bird of dawning singeth all night long:
And then, they say, no spirit dare stir abroad;
The nights are wholesome; then no planets strike,
No fairy takes, nor witch hath power to charm,
So hallowed and so gracious is the time.
– William Shakespeare
