Author of the Book: Comte de Mirabeau
Based on Thomas Jefferson's first-hand recollections to friends and family in later years, Jefferson—while serving in Paris—became closely acquainted with Mirabeau,2 greatly admired his oratory,3 and "was an eye and ear witness" to much of it.4 During his time in France, Jefferson provided to Mirabeau materials he had written.5 6
Mirabeau was a prolific writer, authoring dozens of books and pamphlets in his relatively short life. His first major work, Essai sur le despotisme (Essay on Despotism), was published anonymously and printed in London in 1775.7 It echoed ideals that were the basis for the American Revolution and that appeared in much of Mirabeau's subsequent writing.
A second tract—Avis aux Hessois (Advice to the Hessians), published in 1777—denounced the traffic carried on by German princes in the flesh of their subjects. Mirabeau noted the irony of Hessians being paid to fight Americans who, in turn, were fighting for the fundamental rights of people such as the Hessians.8
Other influential works by Mirabeau included Considerations Sur l'Ordre de Cincinnatus (20 September 1784), or Considerations on the Order of Cincinnatus—a pro-democracy work translated into English by Mirabeau's friend Sir Samuel Romilly in 1785 and distributed widely in England and America.9 Mirabeau used Thomas Jefferson's Declaration of Independence as the basis for many of the egalitarian arguments made in Cincinnatus,10 and Mirabeau's colleague Benjamin Franklin personally provided some of the book's materials to Mirabeau.11
Mirabeau's next publication, De la Caisse d'Escompte (17 May 1785)—the book shown in the foreground of the
1785 Delapierre portrait—contained a scathing analysis of a French
government-controlled financial institution (the Discount Bank). Mirabeau
accurately predicted it was a risky venture doomed to collapse, likely with
serious political repercussions.
In the book's introduction, Mirabeau expressed views on agriculture that mirrored Jefferson's at the time.12 He professed that farming was the most honorable profession and that other endeavors—such as trading shares of the Discount Bank—were little more than speculation based on greed.13
De la Caisse d'Escompte was followed by several financial tracts and other books that made Mirabeau increasingly popular with the Third Estate (commoners) in France. Many of these were banned by the King's Council, including De la Banque d'Espagne, dite de Saint Charles (printed about June 1785) and Lettre du comte de Mirabeau à M. Le Couteulx de la Noraye, sur la Banque de Saint-Charles & sur la Caisse-d'Escompte (printed on 15 July 1785)—the two books Mirabeau wrote just after De la Caisse d'Escompte.14
Role in the Revolution
A moderate, Mirabeau favored a constitutional monarchy built on the model of the United Kingdom. He unsuccessfully conducted secret negotiations with the French monarchy in an effort to reconcile it with the Revolution.
A few days later, his health fading, Mirabeau confided prophetically to a friend: "When I am no more, it will be realized what I was worth. The evils I averted will fall upon France from all quarters; that criminal faction that trembles before me will no longer have any constraint." 16
was honored with one of the most elaborate funerals ever staged in
France—then or since. It was for him that the Panthéon in Paris was converted from a church to a mausoleum for the interment of great Frenchmen.
Mirabeau's Book Collection
In addition to his prolific writing, Mirabeau, like Jefferson, was a voracious reader and book collector. He amassed one of the largest private libraries in France, intending it to be a testament to the progress of mankind.
After he died, the books were sold at an auction that lasted several days.17

 According to Henry S. Randall, "The late Henry Clay informed us that he had heard Mr. Jefferson speak in strong and glowing terms of Mirabeau's matchless power over the minds [of] every class of men. Some of Mr. Jefferson's family entertain similar recollections." (See Henry S. Randall, LL.D., The Life of Thomas Jefferson: In Three Volumes, Vol. 1, J.B. Lippincott & Co., Philadelphia, 1865, p. 527, footnote 2.)
 William Wirt, a U.S. Attorney-General and colleague of Jefferson, described Jefferson's high regard for Mirabeau in a letter dated 6 May 1806 that Wirt wrote to his friend Benjamin Edwards: "He [Jefferson] spoke of him [Mirabeau] as uniting two distinct and perfect characters in himself, whenever he pleased;—the mere logician, with a mind apparently as sterile and desolate as the sands of Arabia, but reasoning at such times with a Herculean force, which nothing could resist; at other times, bursting out with a flood of eloquence more sublime than Milton ever imputed to the cherubim and seraphim, and bearing all before him." (See John P. Kennedy, Memoirs of the Life of William Wirt, Attorney-General of the United States, in Two Volumes, Vol. I, Lea and Blanchard, 1850, p. 137.)
 Mirabeau is perhaps most remembered for a celebrated reply he made to the Marquis de Brézé on 23 June 1789—three weeks before the fall of the Bastille and the beginning of the French Revolution. When, in the name of King Louis XVI, Brézé ordered the National Assembly to disperse, a defiant Mirabeau refused. Jefferson, who was present with the National Assembly when Mirabeau made his famous statement, recalled it as follows: "Tell those who sent you that we shall not move hence but at our own will, or at the point of the bayonet." (See Henry S. Randall, LL.D., The Life of Thomas Jefferson: In Three Volumes, Vol. 1, J.B. Lippincott & Co., Philadelphia, 1865, p. 527, footnote 1.)
 For example, Jefferson wrote to
Mirabeau on 21 August 1786 and provided Mirabeau with copies (French and
English text) of the "Act for
Establishing Religious Freedom"—first drafted by Jefferson in
1779—with the hope that "…the Count de Mirabeau will perhaps be able on
some occasion to avail mankind of this example of emancipating human reason." (The
Papers of Thomas Jefferson, Volume 10, edited by Julian P. Boyd, Princeton University Press, Princeton, New Jersey,
1954, p. 283; see also image below.)
 The research team has not found evidence that Jefferson had established a personal relationship with Mirabeau by mid-to-late 1785, when the Delapierre portrait was painted; however, he surely knew of Mirabeau then because of Mirabeau's earlier writings and because of the close personal relationship that Benjamin Franklin—Jefferson's colleague and ministerial predecessor in Paris—had established with Mirabeau prior to that time.
 Most early copies of Mirabeau's Essai sur le despotisme (Essay on Despotism) were printed in 1776. But a few of the very first, such as one obtained by the research team in June 2005, were published in 1775 (see image below).

 Benjamin Franklin provided Cincinnatus materials to Mirabeau during a meeting at Franklin's residence in Passy, France, that took place on 13 July 1784. Eight weeks later, on 8 September 1784, Franklin wrote a letter to Benjamin Vaughan that was instrumental in helping Mirabeau find a publisher in London for "his dangerous book."
