Jan Baptist Zangrius (died 1606 in Leuven) was a Flemish engraver, publisher, typographer and bookseller. His name is mostly spelled as Johannes Baptista Zangrius, but is also known as de Sanger, de Zangre, Zangre, and Zangré. Biographical data He was active in Leuven between 1595 and 1606 and by all probability he was a relative of the publishers and typographists Petrus (1559–1623) and Philippus Zangrius (1585–1610). In 1601, Zangrius engraved the portraits of Infante Isabella, her husband archduke Albrecht Habsburg, governor of the Low Countries, and Justus Lipsius. These engravings were also part of his 1602 (or 1605) work titled Album Amicorum containing 67 engravings, namely 46 womanly costumes and armorial cartouches, 9 small and 11 bigger armorial engravings. It is one of the earliest examples of heraldic pavilions (by all probability after Jean-Jacques Boissard). The small armorial shields are empty. The womanly costumes were engraved after the tables of Julius Goltzius, to be found in the following title: Jean Jacques Boissard, Habitvs Variarvm Orbis gentium. Habitz de Nations estra:[n]ges. Trachten mancherley Voelcker des Erdskreysz, Cum Priuilegio Caesaro, Cum Priuilegio Regio, 1581 [Mechelen, Caspar Rutz] Zangrius in heraldry According to some authors, Zangrius developed the earliest hatching system in heraldry, identical with the present day hatching method, seen on his armorial chart of Brabant. (Jean Baptiste Zangre, Representation de l'Ancienne et Souveraine Duche de Brabant, ses Villes, Dignitez et Dependences, Comme Lothier, Limborghe et Pays de Outre Meuse, Louvain, 1600. Measures: 49 x 56.3 cm). Though manufactured by Arnold van Rincvelt, it is better known as the armorial chart of Zangrius. The original chart is held by the Helmond Castle-Townhall. The armorial chart of Zangrius was first published in the 81st volume (1964) of the De Nederlandsche Leeuw by F. J. van Ettro. He maintains that the present-day hatching system was invented by Zangrius. The historical background for the coming into existence of the armorial chart was the 6 March 1598 edict of the Spanish king Philip II who detached the Low Countries in his testament from Spain and gave independence to the Netherlands on the occasion of the marriage of his daughter Infante Isabella to archduke Albrecht Habsburg who served as the governor of the province since 1596. The princely consorts marched across Brussels ceremoniously on 5 September 1599. As Albrecht Habsburg died in 1621 without heirs, the country returned to the Spanish crown, as was stated in the
