Ghost (Hamlet)

The ghost of Hamlet's father is a character from William Shakespeare's play Hamlet. In the stage directions, he is referred to as "Ghost". His name is also Hamlet, and he is referred to as King Hamlet to distinguish him from the Prince, his son and the protagonist of the story.

The Ghost appears four times throughout the play: in Act I, Scene i; in the continuum of Act I, Scenes iv and v; and in Act III, Scene iv. The Ghost arrives shortly after midnight in at least two of the scenes, and in the other scenes, all that is known is that it is night.

The Ghost first appears to two soldiers—Bernardo and Marcellus—and Hamlet's friend, Horatio. The men draw their swords and stand in fear, requesting that Horatio, as a scholar, address the Ghost. Horatio asks the Ghost to speak, and reveal its secret. It is about to do so when the cock crows, signalling morning, and the Ghost instead disappears. In this scene, the Ghost is clearly recognised by all present as the King, dressed in his full armour. Marcellus notes that the Ghost had appeared to the castle guards twice before. Talk of spectral visitations has unsettled the night watch. Francisco, whom Bernardo relieves on guard duty says, "For this relief much thanks; 'tis bitter cold,/And I am sick at heart."

Seeing the Ghost arrayed in a military aspect, and aware that the Norwegian crown prince Fortinbras is marshalling his forces on the frontier, Horatio recognises that the appearance of the Ghost must portend something regarding matters of state.

Horatio then persuades Prince Hamlet into staying up with the guards to see if the Ghost returns. At midnight, the Ghost appears, and beckons Hamlet to follow. Once alone, the Ghost describes his wanderings on the earth, and his harrowing life in Purgatory, since he died without receiving last rites.

"...but know, thou noble youth,
The serpent that did sting thy Fathers life,
Now wears his crown."

He tells the young Hamlet that he was poisoned and murdered by his brother, Claudius, the new King of Denmark, and asks the prince to avenge his death. He also expresses disgust at his wife, Gertrude, for marrying Claudius, but warns Hamlet not to confront her, but to leave that to Heaven. Later, Prince Hamlet returns to his friends and has them swear on his sword to keep what they have seen a secret. When they resist, the Ghost utters the words "Swear" and "Swear on the sword", from below the stage, until his friends agree.

Prince Hamlet, fearing that the apparition may be a demon pretending to be King Hamlet, decides to put the Ghost to the test by staging a play that re-enacts the circumstances that the spirit claims led to his death. Claudius' reaction is one of guilt and horror, and Prince Hamlet is convinced that the Ghost is, in fact, his father.
