subtitle of the book was pour sculpteurs, peintres et orfebvres, pour s'en servir aux ornemens d'inscriptions, emblemes et armes (for sculptors, painters and goldsmiths, to be used for inscriptions, emblems and coats of arms), showing that the intention of the book was to serve as guidelines for painters, sculptors and goldsmiths. Architectural designs In 1620 he designed the Augustine church which stood on Place de Broukere in Brussels from its completion in 1642 to its demolition in 1893. The facade of the building now forms part of the Church of the Holy Trinity on Parvis de la Trinite in Brussels. One month after the publication of his Premier Livre d'Architecture he was asked to complete the Jesuit church in Brussels (destroyed in 1812). The church's construction had been started in 1606 with Hendrik Hoeimaker as the building master. His first building design was of great importance both for his own career and for its influence on his contemporaries. His Jesuit church played a key role in the evolution of the Flemish early Baroque even more so than the Saint Carolus Borromeus Church in Antwerp which was designed by Franciscus Aguilonius and Peter Huyssens and was built at the same time. His Baroque church showsthe influence of his Roman models. The primary Roman models include the Church of Saint Susanna by Carlo Maderno, the designs of Giacomo Barozzi da Vignola for the Jesuit Church which were not executed and the facade of the Jesuit Church which were built by Giacomo della Porta in 1577. Franquart's sole original contribution to these models is the addition of an attic (a story above the cornice of the façade), which adds an extra dimension to the facade, while not entirely breaking with the horizantality of Renaissance architecture. Franquart's Jesuit Church also incorporated local traditions as the facade hid a Flemish Late Gothic building (in part inherited from Hoeimaker's original design) characterised by its verticalism and interior rib-vaulting. Tuscan columns carried the rib-vaults, decorated in the centre by escutcheons, a treatment of the nave that was echoed by many, including Huyssens at St. Walburga Church in Bruges. In 1620 Franquart designed the Augustine church in Brussels. Various elements of his design, including the use of consecutive double columns, broken frontons and boldly decorated light-openings in various shapes, established a new architectural style that became known as the Brabant Baroque. He used a comparable design for the
