What do the players pantomime in Hamlet?

In "Hamlet," players pantomime a play called "The Murder of Gonzago," which mirrors the circumstances of King Hamlet's death. This performance serves as a crucial plot device, intended to provoke King Claudius's guilt and confirm his role in the murder. The players' enactment highlights themes of appearance versus reality and the transformative power of theater, as Hamlet seeks to reveal the truth through their actions. Ultimately, the pantomime acts as a catalyst for the unfolding tragedy.
