His work is defined by an almost obsessive attention to small details and smooth surfaces. He frequently returned to specific themes, such as elderly hermits praying in rocky grottoes or scholars surrounded by books. These scenes often include a specific set of objects: a skull, a crucifix or a guttering candle. He used thin brushes and multiple layers of oil paint to create a porcelain-like finish that hides any trace of a brushstroke. This technique creates a sense of stillness and quiet contemplation.

Modern collectors value these paintings for their technical precision and muted colours. The small scale of his works makes them suitable for contemporary interiors where space is limited but detail is appreciated. His depictions of solitary figures offer a counterpoint to the noise of modern life. They invite the viewer to look closely at the textures of stone, paper and fabric. These prints offer a view into the private, intellectual world of the seventeenth-century Dutch Republic.
