Govert van Slingelandt (1623-90), lord of Dubbeldam. With his first wife Christina van Beveren and their two sons

Mytens employed oil paint to render the luxurious textures of the sitters' attire, such as the man's fur-lined cloak and the woman's shimmering silver gown, which shines like polished metal. His technique creates a sense of opulence and refinement, contrasting with the soft, distant landscape background featuring a rocky hill and trees under a muted sky. This attention to detail and material richness was characteristic of his commissions.

Johannes Mytens was a prominent portraitist active in The Hague during the Dutch Golden Age. Trained by Anthony van Opstal and Nicolas van der Horst, he specialized in depicting the affluent members of society, catering to the rising merchant class and aristocracy. This work exemplifies his skill in capturing the refined image desired by his elite patrons, reflecting the artistic and social conventions of 17th-century Dutch portraiture.

Painted in 1657, this family portrait by Johannes Mytens has become a significant piece within the Dutch Golden Age collection at the Rijksmuseum. Its inclusion in such a national institution underscores its historical and artistic value, serving as a testament to the societal and artistic trends prevalent in the Netherlands during the 17th century.
