Manuscript notarial act. Single vellum leaf, written in brown ink in a notarial cursive hand, with the signature of Bourcier at the end. Notarial act headed by Florimond de Beaune (16011652) in his early role as conseiller du roi at Blaye, predating his later renown as a mathematician and correspondent of Descartes. This notarial deed records that Madame?Pepin and her son paid 45?livres, 10?sols in dépens (legal costs), applied toward the consignation of a larger principal sum of 1,100?livres. Executed at Blois and signed by the notary Bourcier, it reflects a partial settlement within an ongoing financial proceeding. The act is headed by the formal authority of Florimond de?Beaune (16011652), then serving as conseiller du roi. Born in Blois on 7 October 1601 and deceased there on 18 August 1652, de?Beaune was a French jurist and an erudite amateur mathematician. Though mentioned here in his judicial capacity, Florimond de Beaune is best remembered as the first major interpreter of Descartes's geometry. His Notae brevesan introduction printed with the 1649 Latin edition of La Géométriehelped disseminate Cartesian methods, and in 1638 he posed to Descartes the celebrated "inverse tangent" problem, an early instance of a differential equation. A jurist by profession, de Beaune also assembled a substantial scientific library and maintained an observatory at his estate in Blois, embodying the humanist scholar-official of seventeenth-century France. .
