Cicero was a famous Roman writer and orator. ... Cicero was also a very talented author. He left many of his speeches written down, and others copied them, so we still have them today. As they did with Julius Caesar, people came to hear Cicero speak.
I've done a bit of research on your question, and I have found that the answer is that he raised $1 billion dollars off of donors. I hope this is helpful. =]
