An example of van Coques' work in this genre is the "Interior with Figures in a Picture Gallery" (Mauritshuis, The Hague). This was likely a collaboration with Dirck van Delen who painted the architectural setting. It was believed earlier that it was Wilhelm Schubert van Ehrenberg who painted the architectural setting. The composition depicts a large gallery with many pictures on the walls and standing on the floor. A man and woman are sitting at a table on which are placed various sculptures and two children stand next to them. Possibly the picture depicts the Antwerp collector Antoon van Leyden (1626-1686), his wife Marie-An van Eywerven and their two daughters. The couple appear in the process of appreciating and discussing some of the artworks in the gallery. This gallery painting represents a later development in the genre initiated by David Teniers the Younger, which excludes non-art objects from the gallery. The figures in the gallery painting are portrayed as forming part of an elite who possess privileged knowledge of art. The genre of gallery paintings had by that time become a medium to accentuate the notion that the powers of discernment associated with connoisseurship are socially superior to or more desirable than other forms of knowing. The pictures depicted in the room appear to represent works of leading Antwerp painters. The presence of children in this type of composition has been explained by the popularity in the Netherlands during the 1660s and 70s of genre scenes showing domestic interiors and 'ordinary' people.
