It was about to speak when the cock crew

Barnardo
It was about to speak when the cock crew.
Horatio
And then it started like a guilty thing
Upon a fearful summons.Simile I have heard
The cock, that is the trumpet to the mornMetaphor,
Doth with his lofty and shrill-sounding throat
Awake the god of day, and at his warning,
Whether in sea or fire, in earth or air,
Th' extravagant and erring spirit hies
To his confine; and of the truth herein
This present object made probation.

But look, the morn in russet mantle clad
Walks o’er the dew of yon high eastward hill.Anastrophe, Metaphor & Personification

Marcellus
It faded on the crowing of the cock.
Some say that ever ’gainst that season comes
Wherein our Savior’s birth is celebrated,
This 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 that time.
Horatio
So have I heard and do in part believe it.
But look, the morn in russet mantle clad
Walks o’er the dew of yon high eastward hill.Anastrophe, Metaphor & Personification
