| I come to bury Caesar, not to praise him. |
| The evil that men do lives after them, |
| The good is oft interred with their bones; |
| So let it be with Caesar. The noble Brutus |
| Hath told you Caesar was ambitious; |
| If it were so, it was a grievous fault, |
| And grievously hath Caesar answer'd it. |
| Here, under leave of Brutus and the rest- |
| For Brutus is an honorable man; |
| So are they all, all honorable men- |
| Come I to speak in Caesar's funeral. |
| He was my friend, faithful and just to me; |
| But Brutus says he was ambitious, |
| And Brutus is an honorable man. |
| He hath brought many captives home to Rome, |
| Whose ransoms did the general coffers fill. |
| Did this in Caesar seem ambitious? |
| When that the poor have cried, Caesar hath wept; |
| Ambition should be made of sterner stuff: |
| Yet Brutus says he was ambitious, |
| And Brutus is an honorable man. |
| You all did see that on the Lupercal |
| I thrice presented him a kingly crown, |
| Which he did thrice refuse. Was this ambition? |
| Yet Brutus says he was ambitious, |
| And sure he is an honorable man. |
| I speak not to disprove what Brutus spoke, |
| But here I am to speak what I do know. |
| You all did love him once, not without cause; |
| What cause withholds you then to mourn for him? |
| O judgement, thou art fled to brutish beasts, |
| And men have lost their reason. Bear with me; |
| My heart is in the coffin there with Caesar, |
| And I must pause till it come back to me."""; |
