In William Shakespeare's play, "Julius Caesar," Decius convinces Caesar that he should go to the Senate by telling him that he will receive a crown. This appeals to Caesar's vanity and he agrees to go. The discussion between Decius and Caesar occurs in Act 2, Scene 2.
In the play, Caesar's wife Calpurnia has a dream that something ominous will occur at the Senate. She asks Caesar to stay away, and he agrees to remain at home. Decius is one of the conspirators planning to kill Caesar and it is his job to ensure that Caesar is at the Senate. He tells Caesar that he should not give in to his wife, and flatters him so that he agrees to go to the Senate.
