Career
De Rouck developed a late hatching system (1645), but failed to make a serious cut. The engravings, according to his 1673 work, were possibly made by his relatives. The portrait of the vicar Lambertus de Rycke (†1658) seen in the book was engraved by West de Rouck.
F. J. van Ettro maintained, he was familiar with the hatching system of Zangrius.
However, it seems more evident that even Butkens might have known Zangrius’ system despite his hatching table being radically different from that of Zangrius because he also applied the same oval escutcheon in his hatching table similar to what Zangrius did in his system.
