About Antoine Loysel
Lived 1536 – 1617 (aged 81). Antoine Loysel was a French jurist-consultant, lawyer, magistrate and jurist.
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,
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 expression of French law. By merging the rules of many customs and Roman law, Loysel set the foundation for French law.
Quotes
