And when they were alone together, the spirit broke silence and told him that he was the ghost of Hamlet, his father, who had been cruelly murdered, and he told the manner of it; that it was done by his own brother Claudius, Hamlet’s uncle, as Hamlet had already but too much suspected, for the hope of succeeding to his bed and crown. That as he was sleeping in his garden, his custom always in the afternoon, his treasonous brother stole upon him in his sleep and poured the juice of poisonous henbane into his ears, which has such an antipathy to the life of man that, swift as quicksilver, it courses through all the veins of the body, baking up the blood and spreading a crust-like leprosy all over the skin. Thus sleeping, by a brother’s hand he was cut off at once from his crown, his queen, and his life; and he adjured Hamlet, if he did ever his dear father love, that he would revenge his foul murder. And the ghost lamented to his son that his mother should so fall off from virtue as to prove false to the wedded love of her first husband and to marry his murderer; but he cautioned Hamlet, howsoever he proceeded in his revenge against his wicked uncle, by no means to act any violence against the person of his mother, but to leave her to Heaven, and to the stings and thorns of conscience. And Hamlet promised to observe the ghost’s direction in all things, and the ghost vanished. And when Hamlet was left alone he took up a solemn resolution that all he had in his memory, all that he had ever learned by books or observation, should be instantly forgotten by him, and nothing live in his brain but the memory of what the ghost had told him and enjoined him to do. And Hamlet related the particulars of the conversation which had passed to none but his dear friend Horatio; and he enjoined both to him and Marcellus the strictest secrecy as to what they had seen that night. The terror which the sight of the ghost had left upon the senses of Hamlet, he being weak and dispirited before, almost unhinged his mind and drove him beside his reason. And he, fearing that it would continue to have this effect, which might subject him to observation and set his uncle upon his guard, if he suspected that he was meditating anything against him, or that Hamlet really knew more of his father’s death than he professed, took up a strange resolution, from that time to counterfeit as if he were really and truly mad; thinking that he would be less an object of suspicion when his uncle should believe him incapable of any serious project, and that his real perturbation of mind would be best covered and pass concealed under a disguise of pretended lunacy.
