Appian of Alexandria Civil Wars 2.19.142

[142] While Brutus was still speaking in this sort, and after the assembly was dissolved, his discourse was approved by all as being entirely just. He and his associates were admired as men of intrepidity, and as peculiarly the friends of the people. The latter were favorably inclined toward them, and promised to coöperate with them on the following day. At daybreak the consuls called the people to an assembly and communicated to them the decisions of the Senate, and Cicero pronounced a long encomium on the decree of amnesty. The people were delighted with it and invited Cassius and his friends to come down from the Capitol. The latter asked that hostages be sent to them in the meantime, and, accordingly, the sons of Antony and Lepidus were sent. When Brutus and his associates made their appearance they were received with shouts of applause, and when the consuls desired to say something the people would not allow them to do so, but demanded that they should first shake hands with these men and make peace with them, which was done. The minds of the consuls were much disturbed by fear and envy lest the conspirators should get the upper hand of them in other political matters.
