A detailed seventeenth-century engraving by Theodor Matham, depicting the Dutch statesman Johan Maurits van Nassau-Siegen in formal military attire.

This engraving by Theodor Matham depicts Johan Maurits van Nassau-Siegen, a prominent Dutch statesman and military officer. Matham, a skilled printmaker of the Dutch Golden Age, employs precise line work to capture the textures of the subject's armour, the soft lace of his collar, and the heavy folds of the curtain behind him. The composition follows the conventions of seventeenth-century portraiture, placing the sitter within an oval frame that includes a Latin inscription. To the right, a plumed helmet rests on a ledge, serving as a traditional symbol of military authority and status.

Johan Maurits is shown in three-quarter profile, holding a baton of command, which reinforces his role as a leader. The engraving technique allows for a high degree of detail, particularly in the rendering of the metal surfaces and the facial features of the sitter. The play of light across the polished steel of the breastplate demonstrates the technical proficiency required for such works during this period. The surrounding oval border contains text that identifies the subject and his titles, a common feature in prints intended for circulation among the educated classes of the time.

This print provides a clear example of the portraiture style used to document the figures of the Dutch Republic. The work is executed with a focus on clarity and formal representation, typical of the period's approach to commemorative portraiture. The inclusion of the helmet and the baton provides context for the sitter's career, while the overall arrangement maintains a sense of balance and order. This piece is a representative example of the printmaking traditions that flourished in the Netherlands during the seventeenth century, documenting the appearance and status of individuals who shaped the political and military affairs of the era.
