The primacy of developing a hatching method belongs undoubtedly to Zangrius. In comparison to his system, Petra Sancta and de la Colombière made only minor changes to Zangrius‘ system such as different hatching for the colour Sable. It seems that de la Colombière preceded Petra Sancta and the armorial chart of Zangrius published in French could possibly be known to him pretty well. The artists from the Spanish Low Countries (where by all probability the heraldic hatching systems were invented), that is to say from the neighbouring territories to France, visited Paris very often.
