The subsequent history of prose was said to be either a reaction against or a return to his style

It's easy for people to identify Shakespeare or the King James Bible as major cultural influences. Then you might get Einstein.

One who is seldom mentioned other than in the most refined of groups is Cicero. I have always enjoyed his work and have found it just remarkable how much of a person can be revealed via words from two millennia ago. A reminder of Cicero's influence from the Wikipedia entry.

Marcus Tullius Cicero (/ˈsɪsɨroʊ/; Classical Latin: [ˈmaːr.kʊs ˈtʊl.li.ʊs ˈkɪ.kɛ.roː]; Greek: Κικέρων, Kikerōn; 3 January 106 BC – 7 December 43 BC) was a Roman philosopher, politician, lawyer, orator, political theorist, consul and constitutionalist. He came from a wealthy 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, "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.

Petrarch's rediscovery of Cicero's letters is often credited for initiating the 14th-century Renaissance in public affairs, humanism, and classical Roman culture. According to Polish historian Tadeusz Zieliński, "Renaissance was above all things a revival of Cicero, and only after him and through him of the rest of Classical antiquity." The peak of Cicero's authority and prestige came during the 18th-century Enlightenment, and his impact on leading Enlightenment thinkers such as John Locke, David Hume, and Montesquieu was substantial. His works rank among the most influential in European culture, and today still constitute one of the most important bodies of primary material for the writing and revision of Roman history, especially the last days of the Roman Republic.

Interesting. I am not sure I have ever considered the connection between Cicero and Locke, Hume et al. Makes sense.
