What warning does Artemidorus give to Caesar?

Artemidorus warns Caesar to beware of Cassius because he believes that Cassius is a threat to his life. In the context of the play "Julius Caesar" by William Shakespeare, Artemidorus is a soothsayer who recognizes that there are individuals who plot against Caesar. His warning emphasizes the idea that Cassius, who is portrayed as a cunning and envious character, is particularly dangerous. This moment underscores the theme of betrayal and the importance of being cautious about those who may not have your best interests at heart. Artemidorus's attempt to deliver this warning to Caesar represents the foreshadowing of the tragic events that unfold later in the play, highlighting the tension between fate and free will.
