“Caesar, beware of Brutus”

“Caesar, beware of Brutus” is the opening of Artemidorus’s written warning to Caesar in a street near the Capitol. Its significance lies in the way it turns a private paper into a compact warning of conspiracy: it names the men whose intentions Caesar should distrust, then insists that they share a purpose against him.

Form and Content

The warning proceeds as a sequence of direct instructions. After naming Brutus, it tells Caesar to take heed of Cassius, avoid Casca, watch Cinna, distrust Trebonius, and mark Metellus Cimber; it then states that Decius Brutus does not love him and that Caesar has wronged Caius Ligarius. The accumulating names make the threat specific rather than abstract, while the commands press for immediate vigilance.

The paper then gathers its accusations into a single conclusion: “There is but one mind in all these men, and it is bent against Caesar.” The phrasing presents the named men not as separate risks but as participants in a shared design. The warning turns from identifying that design to stressing Caesar’s vulnerability: “If thou beest not immortal, look about you: security gives way to conspiracy.”

Dramatic Function

The scene places Artemidorus on a street near the Capitol, entering while reading the paper. The expression therefore belongs to a written appeal being carried toward Caesar, rather than to a conversation already held between them. Its imperative opening makes the danger legible at once, and its progression from names to a collective accusation supplies the reason for the warning.

The paper closes with “The mighty gods defend thee!” and the signature “Thy lover, ARTEMIDORUS.” The personal sign-off contrasts with the warning’s catalogue of political danger: the message is at once an alert about conspiracy and an appeal from someone who professes attachment to Caesar. The scene establishes the warning’s urgency and its intimate address without stating whether Caesar will heed it.
