Antoinette d'Aubeterre (1532–1580) was a French noble woman, who received a good classical education, learning mathematics from François Viète. François was her legal advisor, personal secretary, and tutor to Antoinette and her husband Jean V de Parthenay's daughter Catherine de Parthenay. Catherine married at about the age of 14 to Charles de Quelennec. Catherine was kidnapped by her husband in the middle of a scandal and Antoinette intervened to free her daughter.
Antoinette d'Aubeterre, the daughter of François II Bouchard, Seigneur d'Aubeterre and Isabelle de Saint-Seine was born in 1532.
Antoinette d'Aubeterre hired François Viète, a jurist, as her legal adviser to help her navigate legal issues that arose between the Calvinists (Huguenots) and the Catholics. He was born a Catholic, and did not personally engage in religious disputes. From 1564 to 1571, he worked as her personal secretary.
Antoinette d'Aubeterre and Jean V of Parthenay were married on 3 May 1553. Their daughter, Catherine de Parthenay, was born on 22 March 1554 at Château du Parc-Soubise.
The couple had a clear division of labor. Jean V concerned himself with business and political affairs that often took him away from home. Antoinette managed the financial and other private affairs that concerned her family and their relationships in their community.
François Viète, who had been Antoinette's former mathematics tutor, was hired to be her daughter Catherine's tutor. Viète taught Catherine geography, current discoveries, cosmographic knowledge, and mathematics, from 1564 to 1568. While he worked for Antoinette d'Aubeterre, he worked on trigonometric functions that were published in two of his books (1579). Viète co-founded modern algebra. He also published manuscripts of memoirs and genealogy of the Parthenays. Antoinette was his patron.
Catherine married Charles de Quelennec in 1568 (when she was about 14). They had a difficult marriage and her husband imprisoned his wife at a castle in Brittany.
On 6 September 1570, as Catherine was about to be kidnapped, she wrote a letter to her mother Antoinette. In it, she said she was being taken against her will and could not provide the care she wanted to provide for her ill mother. She stated she was the same as she "was on the eve of my wedding and that I have always been since my birth". Catherine snuck letters out of the castle. They were written in invisible ink of citrus juice and in Greek and Latin to her mother Antoinette d'Aubeterre and her former tutor. Antoinette contacted the Duke of Anjou (future King Henri III (1574–1589)) and his mother Catherine de Medici for guidance. They took Quelennec's side, but they would not have her detained. Antoinette then wrote to King Charles IX and the case went before the Grand Council on 11 September 1571, after which it was referred to boards of doctors and judges. Quelennec died the night of 23–24 August 1572, during the St. Bartholomew's Day massacre. Antoinette's daughter became a widow at the age of 18.
Their houses was looted, but noblemen of the king saved their furniture and the Antoinette's and her daughters lives. The following year she went to the Protestant city of La Rochelle for safety away from the Massacre.
John Calvin lived in Geneva from 1542 until he died in 1564 and he maintained contacts with others through correspondence. Among his correspondents were eighteen noblewomen, their communication with Calvin provides insight into the women's role in the advancement of Protestantism in the 16th century, which led to a political and military actions. Calvin needed the support of the aristocrats for change. Many of the noblewomen interested in reform, generally well-educated, developed rich spiritual lives where they read Scripture and debated about theology. With Calvinism, men and women had direct relationships with God.
In 1553, the Catholic Army surrounded and cut off the city of Lyon. Jean led the resistance, and the Catholic Army decided to end the battle by threatening Jean's wife and daughter to force him to step aside. The royal court intended to have Antoinette and her daughter Catherine stabbed to overcome Jean's resistance against the Catholics. Antoinette wrote to Jean that she would prefer to remain faithful to the cause and perish than have Jean back down. This comes from the Testament d’Antoinette d’Aubeterre, Dame de Soubise, du Parc et de Mouchamps that she made in 1570.
On the eve of entering Orléans, Duke François de Guise was killed by Poltrot de Méré. When questioned, the latter denounced Théodore de Bèze, Admiral de Coligny and Jean de Parthenay. The admiral responded to these accusations but Jean de Parthenay, who was locked up in Lyon, could not add his name to the protest of 12 March 1563, signed by Châtillon, La Rochefoucauld, and De Bèze.
The presumptions against Jean de Parthenay are that during the siege of Lyon he spoke of killing de Guise. Moreover, during the siege, Jean de Parthenay sent Poltrot to Admiral de Coligny and their accusers saw in this evidence of a plot.[1]
Antoinette d'Aubeterre hired François Viète, a jurist, as a legal adviser, who addressed suspicions of complicity by Jean V de Parthenay. In Lyon, Jean V and his lawyer researched documents about his actions. Viète also produced a summarization of Jean de Parthenay's behavior the previous year, during his administration of the city of Lyon.
Returning from Moulins at the beginning of the summer of 1566, Jean de Parthenay fell seriously ill. On 8 August 1566, Jean de Parthenay wrote his will and declared that he wants to be buried according to the form and manner observed by the Reformed churches of the kingdom. He died in 1566, possibly of jaundice, the same ailment from which his wife later suffered. Antoinette died in 1580.
