Between 1557 and 1558, he built the Canal de Craponne which enabled irrigation of the Désert de la Crau with water coming from the Durance. De Craponne personally funded the project, with the help of private partners, such as Nostradamus, the reputed seer who, along with his wife Anne Ponsard, acquired a one-thirteenth share in the canal project.[1] (See Canal de Craponne#Contract law for the unforeseen legal and financial consequences over the ensuing 458 years.)
“In the year 1576, 'ledict' Adam de Craponne died of illness in Nantes, Brittany, employed by King Henry III of France to fortify the city, where he was believed to have been poisoned by envious Italian workers, ... He died within 24 hours and was buried in the l'église Notre-Dame”.[4]
According to some sources, he was poisoned by engineers envious of his success.[5]
Contract Law
Adam de Craponne was the unwitting, underlying cause of a notorious case in French contract law that still reverberates 450 years after his death. The original Canal de Craponne investors formally undertook to maintain the canal against a payment of three French sols for every two hectares irrigated by the farmers. Slowly this payment became derisory and out of proportion to the cost of maintenance, so the heirs of Adam de Craponne were granted an increase by the lower court. But in 1876 the farmers sought legal review and the decision of the Court of Appeal of Aix-en-Provence was quashed.[6]
After more than a century of further academic debate, the reform of French contract law (10 February 2016) overruled the Cour de cassation’s infamous decision on Canal de Craponne, according to which even a 300-year-old contract could not be modified to accommodate a change of circumstances that had rendered performance significantly more onerous for one of the parties.[7]
