It faded on the crowing of the cock. Some say that — William Shakespeare

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