Roman historians rarely mentioned Spartacus. How do you explain this?

This is due to the fact that Spartacus showed the whole essence of Roman hegemony over the captured peoples. In addition, he was able to create an entire army that successfully fought against the Roman troops for several years. Rome was able to stabilize the situation only due to the fact that experienced legions were called in, as well as the fact that there was discord in the ranks of the uprising. Thus, the Romans in 71 BC managed to strangle this rebellion.
