Gaius Cassius Longinus, known as Cassius, is a very rational and manipulative person. He is controlling, greedy, and puts forth a lot of effort in the military. Cassius is a senator of Rome. He is a rebel at heart and also wants everything done his way. Cassius is known for "hears no music," which means that he is not evil, but could never be satisfied.
Cassius is a different man to different people, depending on who it is he can be loving or ruthless, gentle or rough, passionate or mean. Caesar's opinion on Cassius is "Yond Cassius has a lean and hungry look; He thinks too much: such men are dangerous." ( l.ii.194). Brutus's opinion is, "The last of all the Romans, fare thee well! It is impossible that ever Rome should breed thy fellow equal." (V.iii.9) Cassius is a envious of Caesars position and fearful of what Rome might become if Caesar becomes the king.
Cassius is not very fond of Caesar and Antony. Part of the reason being, Caesar and Antony do not follow in Cassius’s footsteps. He despises the fact that the Roman people treat Caesar like an idol. More importantly, he hates the way Caesar runs around acting like he is an idol to the Roman people. "Why, man, he doth bestride the narrow world /Like a Colossus, and we petty men / Walk under his huge legs and peep about" (I.ii.10).
Cassius thinks Caesar has a secret plan to become a dictating King. The fact that Caesar rejects the crown offered to him didn't change Cassius’s mind; Cassius thinks the reason being is because Caesar does not want the people to know that he wants to rule Rome and have control of the Romans.
Cassius studied philosophy at Rhodesunder Archelaus and became a fluent speaker in Greek. He was married to Junia Tertia. They had one son in 60 B.C. Cassius’s wife was the half-sister to Brutus. Cassius decided to take part in the Battle of Carrhae; the battle was eventually lost by Marcus Licinius Crassus against the Parthians in 53 B.C.
In 44 B.C. Cassius was promised the governorship of Syria for the following year. Marcus Junius Brutus deeply offended him, and Cassius became one of the busiest betrayers against Caesar, taking a major part in the assassination.
Cassius was forced to withdraw from Rome when he plotted against Caesar; that is when he began the mission to assassinate him. He left Italy for Syria, where he created a large army and defeated Publius Cornelius Dolabella.
Cassius compares himself to a metal-worker as he suggests that even the noblest men can be manipulated. Cassius seduces brutus. First he suggests that the Romans want Brutus to lead them, and then he sent Brutus forged letters telling him to take down Caesar.
Cassius is also responsible for manipulating Brutus into joining the conspiracy; although Brutus may have been thinking of turning against Caesar already. ”Well, Brutus, thou art noble; yet, I see, thy honourable metal may be wrought from that it is...
