A refined 1662 portrait engraving by Robert Nanteuil, depicting the French magistrate Guillaume de Lamoignon with characteristic technical precision.

This engraving by Robert Nanteuil depicts Guillaume de Lamoignon, a prominent French magistrate and the first president of the Parlement of Paris. Executed in 1662, the work demonstrates the technical precision that established Nanteuil as the pre-eminent portrait engraver of the seventeenth century. The subject is presented within an oval frame, a common convention for formal portraiture of the period, which directs the viewer's focus toward the sitter's expression and attire.

Nanteuil employs a sophisticated system of hatching and cross-hatching to render the textures of the subject's clothing, particularly the fur collar and the heavy fabric of his robes. The modelling of the face is achieved through subtle gradations of tone, capturing the individual features of the marquis with clarity. Below the portrait, the inclusion of a coat of arms provides a formal heraldic element, reinforcing the status of the sitter within the French legal and social hierarchy of the time. The Latin inscription surrounding the oval frame identifies the subject and his position, adhering to the tradition of commemorative portraiture.

As a master of the burin, Nanteuil moved away from the more rigid styles of his predecessors, opting for a fluid approach that allowed for a greater sense of volume and character. This print is an example of the high standard of portraiture produced during the reign of Louis XIV, where the depiction of public figures served both as a record of identity and a display of professional standing. The composition remains balanced, with the oval frame providing a clear boundary for the subject, while the heraldic detail at the base adds a decorative finish to the overall design. This print offers a view into the visual culture of the French legal elite during the mid-seventeenth century.
