"Et tu, Brute?" is probably the best-known phrase attributed to Julius Caesar. It sums up, in three words, the pain of betrayal by someone you love. There's just one problem: there is no historical record that Caesar said it. It is, in the form we know it, Shakespeare's invention.
The phrase that tradition consecrated
In the play, the moment is exact: surrounded by daggers, Caesar resists, until he sees his closest friend among the assassins. Then he gives up: "Et tu, Brute? Then give up, Caesar!" The Latin phrase is brief, cutting, definitive. It has become so associated with the scene that almost everyone takes it as fact. But it belongs to theater, not to history: it is a consecration of literary tradition, established by Shakespeare in 1599, and not an excerpt from a Roman chronicle.
The phrase that remained is more theater than history, and Shakespeare fixed it forever.
What ancient sources say
The two main ancient sources on Caesar's death do not confirm the phrase, and even disagree with each other.
Suetonius says that some present would have heard Caesar say, in Greek, when he saw Brutus among the daggers, something like "you too, my son?". Note two points: it would be in Greek, not in Latin, and Suetonius presents it as one report among others, not as certainty. This version, with "my son", still feeds the old rumor about the closeness between Caesar and Brutus.
Plutarch, in turn, says the opposite: that Caesar said nothing when recognizing Brutus. He just covered his face with his toga and stopped resisting, accepting the blow in silence.
Why does this matter
The disagreement between the sources is revealing. When ancient accounts do not agree on what was said, what is left is a scene that is more legendary than documented. Shakespeare, three centuries later, did not invent murder, but he gave it the perfect phrase, the one that collective memory adopted as if it were historical truth.
It's a good reminder of how literature shapes our image of the past. Often, what "everyone knows" about an event doesn't come from the sources, it comes from the artist who shaped it. "Et tu, Brute?" It is false as a record and true as art: it captured, better than any chronicle, what it means to be betrayed by someone you love.

Did Caesar really say "Et tu, Brute"?
Probably not. The Latin phrase "Et tu, Brute?" it is a consecration of literary tradition, established by Shakespeare, and does not appear as a historical record in ancient sources about Caesar's death.
What does Suetonius say about Caesar's last words?
Suetonius reports that some heard Caesar say, in Greek, when he saw Brutus among the murderers, something like "you too, my son?". He records this as one report among others, not as certainty, and the phrase itself fuels the rumor about the relationship between the two.
And what does Plutarch say?
Plutarch tells a different version: that Caesar didn't say anything when he recognized Brutus, he just covered his face with his toga and stopped resisting. The two ancient sources disagree, which shows how the scene became more tradition than history.
