That evening, Cicero and Casca meet on a street in Rome. There has been a terrible storm, and Casca describes to Cicero the unnatural phenomena that have occurred: An owl hooted in the marketplace at noon, the sheeted dead rose out of their graves, and so on. Cicero then departs and Cassius enters. He interprets the supernatural happenings as divine warnings that Caesar threatens to destroy the Republic. He urges Casca to work with him in opposing Caesar. When Cinna, another conspirator, joins them, Cassius urges him to throw a message through Brutus' window and to take other steps that will induce Brutus to participate in the plot. The three conspirators, now firmly united in an attempt to unseat Caesar, agree to meet with others of their party — Decius Brutus, Trebonius, and Metellus Cimber — at Pompey's Porch. They are confident that they will soon win Brutus to their cause.
