Sulla (9.7-10.1)

but in a passion, and having surrendered to his anger the command over his actions, since he thought only of his enemies, and without any regard or even pity for friends and kindred and relations, made his entry by the aid of fire, which made no distinction between the guilty and the innocent. Meanwhile Marius, who had been driven back to the temple of Tellus, made a proclamation calling the slaves to his support under promise of freedom; but the enemy coming on, he was overpowered and fled from the city.

Sulla now called together the senate, and had sentence of death passed on Marius himself and a few others, among whom was Sulpicius the tribune of the people. But Sulpicius was killed, after he had been betrayed by a servant, to whom Sulla first gave his freedom, and then had him thrown down the Tarpeian rock; moreover, he set a price on the head of Marius, an act both ungrateful and impolitic, since it was in his house that he had found refuge and surrendered himself a little before this, and had been let off safe.
