in act 1 scene 3 of julius caesar a violent storm occurs

Casca meets with Cicero, one of the great Roman orators, and tells him he has seen many strange things on the streets of Rome that night including a slave with a burning yet uninjured left hand, a lion loose in the streets, and an owl hooting in the daytime. Cicero tells him men interpret things in their own way, and takes his leave.

Cassius then arrives and tells Casca that there is a reason behind all of the strange events taking place in Rome. Casca asks him, "'Tis Caesar that you mean, is it not, Cassius?" (1.3.78). Casca tells him that the senators are planning to make Caesar a king the next morning. At this news, Cassius draws his dagger and threatens to die before ever allowing Caesar to achieve so much power. Casca shakes hands with Cassius and they agree to work together to prevent Caesar from seizing power.
