Writer 's childhood copy of
De Officiis, bearing the inscription in his hand, "Thys boke is myne Prynce Henry" ("This book is mine, [signed] Prince Henry") According to the Latin scholar Mario Citroni, fellow Latin scholar Emanuele Narducci suggested that the period of history in which Cicero lived and wrote as a protagonist could be defined as a "short century", using historian
Eric Hobsbawm's formula in
The Age of Extremes, not as purely modernizing lens but as a call to contemporaneity to rediscover aspects of archaism and barbarism. Cicero has been traditionally considered the master of Latin prose, with
Quintilian declaring that Cicero was "not the name of a man, but of eloquence itself". The English words
Ciceronian (meaning "eloquent") and
cicerone (meaning "local guide") derive from his name. He is credited with transforming Latin from a modest utilitarian language into a versatile literary medium capable of expressing abstract and complicated thoughts with clarity. Julius Caesar praised Cicero's achievement by saying "it is more important to have greatly extended the frontiers of the Roman spirit than the frontiers of the Roman empire". According to
John William Mackail, "Cicero's unique and imperishable glory is that he created the language of the civilized world, and used that language to create a style which nineteen centuries have not replaced, and in some respects have hardly altered." Cicero was an energetic writer with an interest in a wide variety of subjects, in keeping with the
Hellenistic philosophical and rhetorical traditions in which he was trained. The quality and ready accessibility of Ciceronian texts favored very wide distribution and inclusion in teaching curricula, as suggested by a graffito at Pompeii, admonishing: "You will like Cicero, or you will be whipped." Cicero was greatly admired by influential
Church Fathers such as
Augustine of Hippo, who credited
Hortensius (Cicero's
lost literary work) for his eventual conversion to Christianity, and St.
Jerome, who had a feverish vision in which he was accused of being "follower of Cicero and not of Christ" before the judgment seat. This influence further increased after the
Early Middle Ages in Europe, where more of his writings survived than any other Latin author's. Medieval philosophers were influenced by Cicero's writings on
natural law and innate rights.
Petrarch's rediscovery of Cicero's letters provided the impetus for searches for ancient Greek and Latin writings scattered throughout European monasteries, and the subsequent rediscovery of
classical antiquity led to the
Renaissance. Subsequently, Cicero became synonymous with classical Latin to such an extent that a number of humanist scholars began to assert that no Latin word or phrase should be used unless it appeared in Cicero's works, a stance criticised by
Erasmus. His voluminous correspondence, much of it addressed to his friend Atticus, has been especially influential, introducing the art of refined letter writing to European culture.
Cornelius Nepos, the first century BC biographer of Atticus, remarked that Cicero's letters contained such a wealth of detail "concerning the inclinations of leading men, the faults of the generals, and the revolutions in the government" that their reader had little need for a history of the period. Among Cicero's admirers were
Desiderius Erasmus,
Martin Luther, and
John Locke. Following the invention of
Johannes Gutenberg's printing press,
De Officiis was the
second book printed in Europe, after the
Gutenberg Bible. Scholars note Cicero's influence on the rebirth of religious toleration in the 17th century. Cicero was especially popular with the
Philosophes of the 18th century, including
Edward Gibbon,
Diderot,
David Hume,
Montesquieu, and
Voltaire. Gibbon wrote of his first experience reading the author's collective works thus: "I tasted the beauty of the language; I breathed the spirit of freedom; and I imbibed from his precepts and examples the public and private sense of a man ... after finishing the great author, a library of eloquence and reason, I formed a more extensive plan of reviewing the Latin classics..."
Philosopher Voltaire called Cicero "the greatest as well as the most elegant of Roman philosophers" and even staged a play based on Cicero's role in the
Catilinarian conspiracy, called
Rome Sauvée, ou Catilina, to "make young people who go to the theatre acquainted with Cicero." Voltaire was spurred to pen the drama as a rebuff to his rival
Claude Prosper Jolyot de Crébillon's own play
Catilina, which had portrayed Cicero as a coward and villain who hypocritically married his own daughter to Catiline. Montesquieu produced his "Discourse on Cicero" in 1717, in which he heaped praise on the author because he rescued "philosophy from the hands of scholars, and freed it from the confusion of a foreign language". Montesquieu went on to declare that Cicero was "of all the ancients, the one who had the most personal merit, and whom I would prefer to resemble." Cicero the republican inspired the
Founding Fathers of the United States and the revolutionaries of the
French Revolution.
John Adams said, "As all the ages of the world have not produced a greater statesman and philosopher united than Cicero, his authority should have great weight."
Thomas Jefferson names Cicero as one of a handful of major figures who contributed to a tradition "of public right" that informed his draft of the Declaration of Independence and shaped American understandings of "the common sense" basis for the right of revolution.
Camille Desmoulins said of the French republicans in 1789 that they were "mostly young people who, nourished by the reading of Cicero at school, had become passionate enthusiasts for liberty". In the modern era, American libertarian
Jim Powell starts his history of liberty with the sentence: "Marcus Tullius Cicero expressed principles that became the bedrock of liberty in the modern world." Likewise, no other ancient personality has inspired as much venomous dislike as Cicero, especially in more modern times. His commitment to the values of the Republic accommodated a hatred of the poor and persistent opposition to the advocates and mechanisms of popular representation.
Friedrich Engels referred to him as "the most contemptible scoundrel in history" for upholding republican "democracy" while at the same time denouncing land and class reforms. Cicero has faced criticism for exaggerating the democratic qualities of republican Rome, and for defending the Roman oligarchy against the popular reforms of Caesar.
Michael Parenti admits Cicero's abilities as an orator but finds him a vain, pompous, and hypocritical personality who, when it suited him, could show public support for popular causes that he privately despised. Parenti presents Cicero's prosecution of the Catiline conspiracy as legally flawed at least, and possibly unlawful.
Politician As a politician, Cicero was often the target of criticism, just as he was much praised, from both ancient and modern times. The accusations leveled at him range from inconsistency to vanity. His conduct can be justified if contextualized in the politics of the time, which revolved around game of agreements and conflicts between power groups and noble families who exploited political labels for personal aims. While linking to Greek (), Cicero himself also used the word to describe politics "completely compatible with ... honourable aristocratic behaviour". According to Gábor Hamza, a professor of Comparative Law, Roman Law, and the legal system of Eastern European countries, Cicero's political theory of the state can be attractive to both
conservative and
progressive thinkers. Conservatives appreciate his return to
tradition, while progressives emphasizes his absolute refusal of
autocracy. This is because Cicero's theory of the
state is open to multiple interpretations () as it includes republican ideas, liberty (), the refusal of
tyranny, the
mixed government (), the inviolability of
private property, and political, legal, and
social equality.
Astronomy Cicero had an influence on modern astronomy.
Nicolaus Copernicus, searching for ancient views on earth motion, said that he "first ... found in Cicero that
Hicetas supposed the earth to move." Notably, "Cicero" was the name attributed to size 12 font in typesetting table drawers. For ease of reference, type sizes 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, and 20 were all given different names. == Works ==
