Marcus Vulson de la Colombière

We have only some fragmented data about Vulson de la Colombière's life: even major 19th-century biographies deliver only incomplete information.

Gallicanism served as a means to express his Protestant views in opposition to Catholicism, and he presented them in a way acceptable to the state establishment.

For this reason, it could perhaps be concluded that Vulson de la Colombière was right in claiming the title of the inventor of the hatching system, and accusing Silvester Petra Sancta of copying his method and incorrectly publishing it in his 1638 work, one year before the same hatching system was published by Vulson de la Colombière.

[4] Vulson de la Colombière also maintains that he showed to Petra Sancta his hatching system in the past.

In the title of his 1639 book he directly mentions that hatching is a new method used by copperplate engravings ("suivant l'art des anciens roys d'armes... et une nouvelle méthode de cognoistre les métaux et couleurs sur la taille-douce").

In his 1639 work, Vulson de la Colombière published a hatching table, but did not mention Petra Sancta.
