From the name, "Crixus" means a man with curly hair. It is estimated that he really has curly hair in history, which is unknown. Some people say that gannicus and Spartacus are the same person. Historically, I think Eric and Crixus are the same person.
As far as force is concerned, Crixus is the strongest man around Spartacus and his best friend. Crixus and Spartacus fought to the last in the 50-man battle in the arena. They didn't fight to the death, just played a little trick. Crixus survived and Spartacus won, so he was free and won the name Spartacus. Then Spartacus became a coach, and then he chose to rebel, which was purely a personal ideal. He also planned for this for several years, including colluding with several gladiator schools. ...
As far as commander-in-chief ability is concerned, Crixus is in charge of Spartacus' first legion. Needless to say, the name gannicus, maybe he's just a little leader of a legion or something.
On loyalty, the Senate was shocked when they rushed to the door of Rome. Before that, they didn't realize that slaves could pose such a great threat. By the way, the regular army of Rome is fighting abroad. At this time, there was a crisis, and the distant water couldn't put out the near fire, so crassus threw the duck off the shelf. In order to win Rome directly, Spartacus' plan was to spread false rumors of disagreement with Crixus, and the soldiers were divided into two ways, with the aim of attracting attacks and then encircling them together. But crassus was rich and bribed some people around Spartacus to know the situation in advance, but Spartacus was puzzled and didn't attack. He sent someone to tell Crixus to stay put, and the person in charge of delivering the message was bought by the enemy, so that Crixus led the troops forward and finally entered the encirclement of the enemy. After Crixus died, Spartacus was heartbroken and held a grand cremation.
Later, Spartacus was betrayed by pirates in the later period. In the film version of Spartacus in 2004, Spartacus believed that the long-term way was to escape to Sicily and establish a long-term revolutionary base. (By the way, Crixus in it is a curly-haired idiot, and the director's original intention is to show the limitations of slaves), so being betrayed by pirates is the main reason for the failure of the uprising, but I don't fully agree. Spartacus has experienced from uprising to expansion to attack and flee for life in history. At this time, he was in the period of running for his life, not because the civilians in the team slowed down, but because the team was full of traitors and separatists, and countless people escaped (as if gannicus was one of them). Finally, I had no choice but to die. It was indeed in the heyday of Rome, and the foundation of Rome could not be moved. This makes sense.
