Which line in this excerpt from Shakespeare's Hamlet contains an element of foreshadowing? HORATIO: As thou art to thyself.
Such was the very armour he had on
When he the ambitious Norway combated.
So frowned he once when, in an angry parle,
He smote the sledded Polacks on the ice.
'Tis strange.

MARCELLUS: Thus twice before, and jump at this dead hour,
With martial stalk hath he gone by our watch.

HORATIO: In what particular thought to work I know not,
But in the gross and scope of mine opinion
This bodes some strange eruption to our state.
(William Shakespeare, Hamlet, act I, scene I)
