Alas, my lord, Your wisdom is consumed in confidence. Do not go forth today.
Act III : Scene i
Et tu, Brute?
The soothsayer warned Caesar to beware of the ides of March. Yet Caesar, who is overconfident, ignored the warning given. Even Brutus was as well concerned for Caesar. (Act I: ii : Ln 23 & 24)
Act IV : Scene
To tell thee thou shalt see me at Philippi. (Act IV: : Ln 282)
Calpurnia begs Caesar to not go and stay home. She believes the dream she saw was a bad omen. Caesar was slightly turning to her side but enters Decius to fetch him and ultimately changing Caesar's mind. (Act II: ii : Ln 49 & 50
Act V : Scene
This was the noblest Roman of them all (Act V: v : Ln 67)
So call the field to rest, and let's away (Act V: v : Ln 79)
Metellus approaches Caesar to request that his brother. Publius who has been banished from Rome, be granted permission to return but gets denied because it was a banishment from a lawful decree. That comes where Decius and Ligarius, followed by Casca, comes forward to kneel at Caesar's feet. Casca stabs Caesar first and the others quickly follow, ending with Brutus whom Caesar's heart was broken by. (Act III: ii : Ln 79)
After Brutus and Cassius have fled Rome, Antony then mentions Brutus and Cassius, telling Octavius that they have raised an army. The night on Brutus's Camp, the ghost of Caesar appears to tell Brutus that he will see Brutus again at Philippi. Showing an immense amount of foreshadowing upon Brutus on what will happen later on the play.
Why, I will see thee at Philippi then (Act IV: iii: Ln 285)
Antony and Octavius arrive with their army. They find Brutus dead on the ground and Strato nearby. Strato informs them how Brutus died. He says that of all the conspirators only Brutus believed that he was killing Caesar to uphold the Roman Republic; the others were simply jealous and power hungry. Octavius orders the body placed in his tent and to cease fighting.
Ambition is one of the central themes of Julius Caesar, as well as the reason Brutus cites for Caesar's assassination. In their jealousy of Caesar, however, the Roman conspirators reveal themselves to be among the most ambitious characters in the play.
