Foreshadowing

A sign, statement, or image that anticipates something that will happen later in the work, sometimes visible only to those who reread.

In Julius Caesar

Cry 'Havoc!' and let slip the dogs of war

The prediction of "devastation" and war announces what comes after the scene: the civil war that runs through Philippi. The phrase warns the audience that Caesar's death settles far less than the conspirators believed.

Act III: The Assassination and the Forum, Mark Antony

But this same day / Must end that work the Ides of March begun

Act V: Philippi and the Death of Brutus, Brutus

When you do find him, or alive or dead, / He will be found like Brutus, like himself.

Act V: Philippi and the Death of Brutus, Lucilius
