A detailed 1657 engraving by Jonas Suyderhoef, capturing the likeness of the Dutch legal scholar Adrianus Beeckerts a Thienen.

This engraving by Jonas Suyderhoef depicts Adrianus Beeckerts a Thienen, a legal scholar and professor at the University of Leiden. Executed in 1657, the work demonstrates the technical precision characteristic of the Dutch Golden Age printmaking tradition. Suyderhoef, a master of the burin, employs a sophisticated system of hatching and cross-hatching to model the subject's features and the texture of his garments. The sitter is presented in a bust-length format, wearing the traditional attire of a seventeenth-century academic, including a plain white collar that contrasts with the dark, heavy fabric of his robes.

The composition is balanced and formal, typical of the period's portraiture intended for scholarly or professional display. The background remains neutral, allowing the viewer to focus on the facial expression and the subtle play of light across the sitter's hair and collar. Below the portrait, the plate includes a Latin inscription detailing the subject's name, age, and professional titles, alongside the names of the painter, I.D. Vos, and the engraver, Suyderhoef. This inclusion of text serves both as a record of the sitter's identity and as a decorative element that anchors the image within the conventions of European print culture.

Suyderhoef was particularly noted for his ability to translate the tonal qualities of oil paintings into the monochromatic medium of engraving. His work often involved collaborations with contemporary painters, and this print reflects that collaborative process. The clarity of the line work and the careful attention to anatomical detail provide a clear view of the aesthetic priorities of the mid-seventeenth century. This print remains a representative example of the portrait engravings produced for the intellectual elite of the Dutch Republic, capturing the gravity and status associated with academic life during this era.
