Marcus Tullius, 107 BCE-44 BCE Cicero

Marcus Tullius Cicero (106–43 BCE) was a Roman statesman, orator, and philosopher of the late Republic. He is best known for his speeches and rhetorical and philosophical works, which profoundly shaped Latin prose and later Western thought. Note: The dates in your prompt (107–44 BCE) differ slightly from the well-established ones (106–43 BCE), so I used the latter.
