Tillius Cimber
Lucius Tillius Cimber (died 42 BC) was a Roman senator. He was one of the assassins of Julius Caesar, creating the diversion that enabled the first-striking assassins to attack.
Assassin
Cimber was initially one of Caesar's strongest supporters. Caesar granted Cimber governorship of the provinces of Bithynia and Pontus in 44 BC. He may also have been Praetor in the same year.Cicero once used Cimber's influence on Caesar to help a friend.
It is not known why he joined the conspiracy, but Seneca states that he was motivated by ambition. His role was to set the stage for the attack by presenting to Caesar a petition to recall Cimber's exiled brother Publius. Plutarch states that other assassins then pretended to add their own petitions to Cimber's. According to Suetonius, Caesar gestured him away, but Cimber grabbed hold of him by the shoulders and pulled down Caesar's tunic. Caesar then cried to Cimber "Why, this is violence!" ("Ista quidem vis est!"). At the same time, Casca produced his dagger and made a glancing thrust at the dictator's neck but instead hit his shoulder. The other assassins then joined in.
