Most other known hatching systems also originated in the Low Countries. The tiny hatching table of the above-mentioned Jacob Franquart, to be found in his "Pompa funebris Alberti Pii Austriaci" (1623), was the earliest hatching method after Zangrius. The Cistercian abbot from Antwerp and historian and genealogist Christophe Butkens also developed his own system, but it was used by him in an inconsequent way which led to the misunderstandings and the resultant sudden disappearance of this system. The hatching table of Thomas de Rouck was radically different from that of Zangrius. Aegidius Gelenius was one of the most respected Cologne historians of his time. He developed a late hatching system but it did not gain popularity. Gelenius was deeply influenced by Petra Sancta and both the men met personally several times in Cologne. Gelenius also studied the coats of arms and antiquities of the Rhenish nobility in the territory neighboring the Low Countries. However, Gelenius’ hatching system is identical only at two points with Petra Sancta, indicating that he consciously tried to develop an independent system but failed to make a serious cut, or it can also indicate that Petra Sancta's system was not yet fully developed when they met in Cologne. If this is true, it makes certain the primacy of de la Colombière as the inventor of the hatching system.
