About Jean-Baptiste de Boyer, Marquis d'Argens

Lived 1704 – 1771 (aged 66). Jean-Baptiste de Boyer, Marquis d'Argens was a French writer, philosopher, translator, military personnel and aristocrat.

Jean-Baptiste de Boyer, Marquis d'Argens (24 June 1704 – 11 January 1771) was a French rationalist, author and critic of the Catholic Church, who was a close friend of Voltaire and spent much of his life in exile at the court of Frederick the Great.

Life

Jean-Baptiste de Boyer, later Marquis d’Argens, was born on 24 June 1704 in the southern French town of Aix-en-Provence. He was the eldest of seven children of Pierre-Jean de Boyer and Angélique de L'Enfant, daughter of Luc de L'Enfant (1656–1729), President of the Regional Parliament.

Pierre-Jean de Boyer was Procureur général or Attorney-General for the Regional Parliament of Provence and a member of the Second Estate, the Noblesse de robe or Nobles of the robe. Their rank derived from the possession of judicial or administrative posts and unlike the aristocratic Noblesse d'épée or Nobles of the Sword, they were often hard-working middle-class professionals.

By the mid-18th century, many of these positions had become hereditary, with eldest sons expected to succeed their fathers, marry and have children. Jean-Baptiste rejected a legal career and while the rest of his family were devout Catholics, became a rationalist author and critic of the Church; he later wrote 'I was not my father's favourite child.'

To prevent the division of family estates amongst multiple heirs, younger sons were often required to remain unmarried; of his four younger brothers, three including Alexandre, later Marquis D'Éguilles were enrolled in the Knights of Malta religious order and the other became a priest. His refusal to conform meant he was disinherited in favour of his younger brother Alexandre in 1734 but despite their philosophical differences, the two remained close friends throughout their lives.

In 1749, he married French ballerina and writer Babette Cochois (1725–1780), with whom he had a daughter, Barbe (1754–1814). After many years living in Berlin, he returned to France in 1769, where he died at the Château de La Garde on 11 January 1771; originally buried in Toulon Cathedral, his remains were later moved into the family vault at Le Couvent des Minimes.

Career

While several generations of the de Boyer family held the position of Procureur général, they also had a background in the arts. Jean-Baptiste's great-uncle was the poet and dramatist Abbe Claude de Boyer (1618–1698), while his grandfather, Jean-Baptiste de Boyer (1640–1709), owned a famous art collection, with works by Titian, Caravaggio, Michelangelo, Van Dyck, Poussin, Rubens and Corregio.

In 1719, his father reluctantly purchased Jean-Baptiste a commission in the Régiment de Toulouse, based in Strasbourg. Pierre-Jean de Boyer was made 'Marquis d'Argens' in 1722 and since eldest sons were permitted to use the same title, Jean-Baptiste was also known as Marquis d'Argens. In 1722, he eloped with an actress and fled to Spain, before being taken back to France under military escort. One of his warders was Vicomte d'Andrezel, shortly to become French ambassador in Constantinople; he persuaded Pierre-Jean de Boyer to allow his son to accompany him and they left Toulon at the end of 1723.

D'Argens returned to France in 1724, where he spent the next few years obediently studying law and even acting in a number of legal cases. The 1731 Cadière witchcraft trial appears to have been the point at which he rejected a legal career, while confirming his opposition to the Catholic Church and the Jesuits in particular. He rejoined the army in 1733 during the War of the Polish Succession, serving in the same regiment as his younger brother Luc de Boyer (1713–1772). Wounded at Kehl, he was badly injured in a fall from his horse in 1734, which ended his military career.
