BERNARDO: Who’s there?
FRANCISCO: Nay, answer me: stand and unfold yourself.

Hamlet, Act 1, Scene 1. The opening lines of Hamlet. The guards have been seeing apparitions of the dead king Hamlet on the castle rampards. It is midnight and there is an atmosphere of tension and uncertainty. The lines speaks to the themes of identity and appearance vs reality. They also foreshadow the occasions where characters are faced with the question – who is this person, who is really there?
