# Antoine Loysel

Antoine Loysel, Seigneur of Courroy, Fouilloy and Églantier (16 February 1536 – 28 April 1617) was a French jurisconsult known for collecting the general principles of old French customary law.

## Biography
### Family and youth

Loysel was born in Beauvais, the son of Catherine d'Auvergne and Jean Loisel, an alderman and advisor to the king elected in the election of Beauvais.. His brother, Philippe Loisel, held positions as a civil and criminal lieutenant-general at the bailiwick of Senlis and master of requests for the Duke of Anjou. On 2 August 1563, Loysel married Marie de Goulas (1541–1595), who was a first cousin of Nicolas Goulas and the niece of Jean-Baptiste Dumesnil [fr], a lawyer to the king before the Parlement of Paris. Together, Antoine and Marie had 12 children, and Loysel also became the stepfather of Guillaume Marescot [fr].
"He wanted to devote himself to medicine, like his great-uncle Jean Loysel, physician to Louis XII and François I. His father did not approve, saying that despite the danger to which doctors were forced to expose themselves from day to day, a doctor could only ever be a doctor; but a lawyer could become president and chancellor."
In Toulouse, Loysel met Jacques Cujas, who inspired him to continue his studies in law.
Loysel became friends with Pierre Pithou, to whom he was introduced by a mutual acquaintance.
He was, with Nicolas Bergeron, the executor of the will of Petrus Ramus.

## Career

Successor to Charles Dumoulin, he is considered the first "thinker" of French law.
Loysel was a disciple of Jacques Cujas, whom he followed to Bourges, where he studied the methods of Humanist historians.
In February 1560, he received his lawyer designation in Paris. He became the Attorney General of Paris in 1564.
Some of his notable clients included Francis, Duke of Anjou, brother of Henry III of France, Catherine de Medici, the House of Montmorency, and the chapter of Our Lady of Paris. He ended his career as a public prosecutor at the Chamber of Justice in Limoges.
Loysel was a good follower of mos gallicus - the method of the humanists, which would move him away from the study of Roman law and history. Politically, he was a staunch defender of the king and the powers of the king and would, therefore, consider that the law must be that of the kingdom. He spoke first of a French law before speaking of a "Universal Law of our Kingdom". He believed that customs are "finally reduced to conformity, the reason for a single law". He wrote his work Institutes coutumières in 1607, whose form is Roman and background customary.
Loysel spent 40 years on his collection of the 958 maxims. It is an elegant expression of French law. By merging the rules of many customs and Roman law, Loysel set the foundation for French law.

## Quotes

Loysel liked to find formulas to synthesize the law into a series of legal adages. Many are still valid:
* "Who wants the king, if the law wants."
* "Whoever makes the child must feed him."
* "Daughter betrothed is neither taken nor left; for such a fiance does not marry."
* "In marriage any deceive who can."
* "The habit does not make the monk, but the profession."
* "One binds oxen by the horns, and men by words."
* "Enough done that gets done."
* "To all lords, all honours."
* "It is better to have one "here" than "you will have it" twice.
* "Once is not custom."
* "In crime, [there] is no guarantor."
* "It used to be said: 'To drink, to eat, to sleep together, [it] seems to me to be marriage', but the Church must go there."
* "Who sells the pot, says the word."
* "Who can and does not prevent sins."
