references: Van Ottegen [pp22-25 : "The fact that within two weeks two editions of the 'Discours' were published by different publishing houses requires some explanation, especially because both editions appeared under the protection of a privilege of the King. On 10 April 1668 Nicolas le Gras received a privilege to print the 'Principes, Méditations, Méthode et Dioptrique', ( ... which) was withdrawn on the request of Charles Angot, who claimed to possess a privilege to publish all the works (...). Nevertheless, the case was settled and on 26 April 1668 a privilege was granted to Le Gras with Angot's consent."], Guibert [5].
