The use of poisoning in the play is structured around disloyalty, vengeance, and death. The first encounter of poison in the play is when the king's ghost explains his death to Hamlet. Hamlet Sr. explains how Claudius used the poison in his ear to kill him. "Upon my secure hour thy uncle stole, With juice of cursed hebona in a vial And in the porches of my ears did pour" (1.2.68-70). The picture shows an old-time bottle labeled "poison" which I believe matches the ongoing trend of Hamlet.
