We have only some fragmental data about the life of Marcus Vulson de la Colombière. He visited Paris in 1618, but by all probability, until 1635 he was staying in Grenoble as he was a royal counselor in the Dauphiné parliament. He also published a book in the spirit of the Gallicanism in Geneva that year. Colombière's ideas suited the king's taste too, as a result he departed Grenoble and settled in Paris, where he devoted his entire energy to study heraldry. His next book was published in Paris in 1638. He had wide-ranging correspondence with the most renowned heraldists of his time. For this reason, it could perhaps be concluded that de la Colombière was right in claiming the title of the inventor of the hatching system, and accusing Petra Sancta of copying his method and incorrectly publishing it in his 1638 work ("Tesserae gentilitiae", Rome 1638), one year before the same hatching system was published by de la Colombière ("Recueil de plusieurs pièces et figures d'armoiries...", Paris 1639). However, the earlier book of Petra Sancta from 1634 had a hatching table as well. On page 37 of his title "La Science Heroїque" (1644), Colombière maintains that Petra Sancta simply copied his system without any changes. De la Colombière also mentions the book publishers and copperplate engravers as the users of the hatching system.
