"Marcus Tullius Cicero", was a Ancient Rome/Roman philosopher, politician, lawyer, orator, List of political theorists/political theorist, Roman consul/consul and Constitution of the Roman Republic/constitutionalist. He came from a wealthy Municipium/municipal family of the Roman equestrian order, and is widely considered one of Rome's greatest orators and prose stylists.
His influence on the Latin language was so immense that the subsequent history of prose in not only Latin but European languages up to the 19th century was said to be either a reaction against or a return to his style. According to Michael Grant (author)/Michael Grant, "the influence of Cicero upon the history of European literature and ideas greatly exceeds that of any other prose writer in any language". Cicero introduced the Romans to the chief schools of Greek philosophy and created a Latin philosophical vocabulary (with neologisms such as humanitas, qualitas, quantitas, and essentia) distinguishing himself as a linguist, translator, and philosopher.More Cicero on Wikipedia.
