The concept of eloquence dates the ancient Greeks, Calliope, (one of the nine daughters of Zeus and Mnemosyne) being the Muse of epic poetry and eloquence.
Eloquence derives from the Latin roots: ē (a shortened form of the preposition ex), meaning "out (of)," and loquor, a deponent verb meaning "to speak." Thus, being eloquent is having the ability to project words fluidly out of the mouth and the ability to understand and command the language in such a way that one employs a graceful style coupled with the power of persuasion. Petrarch (Fracesco Petrarca), in his study program of the classics and antiquity (Italian Renaissance) focused attention on language and communication. After mastering language, the goal was to reach a “level of eloquence”, to be able to present gracefully, combine thought and reason in a powerful way, so as to persuade others to a point of view. Petrarch encouraged students to imitate the ancient writers, from a language perspective, combining clear and correct speech with moral thought. The Renaissance humanists focused on the correlation of speech and political principles as a powerful tool to present and persuade others to particular concepts. At the core of presentations was the use of graceful style, clear concise grammar and usage, and over time the insertion of rational and emotional arguments.
In modern times, colloquial speech entered into presentation styles deemed eloquent.
Other speakers and speeches termed eloquent:
Famous politicians in modern times Franklin D. Roosevelt, Winston Churchill, Joseph Stalin, Adolf Hitler, Joseph Goebbels and Benito Mussolini each spoke and wrote points of view in eloquent style and substance resulting in actions that brought the world to war World War II. More contemporary politicians with similar eloquent qualities include Tony Blair, Nicolas Sarkozy, Bill Clinton, David Cameron, and Barack Obama.
Eloquence is both a natural talent and improved by knowledge of language, study of a specific subject to be addressed, philosophy, rationale and ability to form a persuasive set of tenets within a presentation.
"True eloquence," Oliver Goldsmith says, "Does not consist ... in saying great things in a sublime style, but in a simple style; for there is, properly speaking, no such thing as a sublime style, the sublimity lies only in the things; and when they are not so, the language may be turgid, affected, metaphorical, but not affecting." (Of Eloquence, 1759)
