A formal eighteenth-century engraving by Johann Georg Wille, depicting the French financial official Jean de Boullongne within an architectural frame.

This engraving by Johann Georg Wille depicts Jean de Boullongne, a significant figure in the French financial administration during the eighteenth century. Wille, a German engraver who spent the majority of his career in Paris, achieved a high level of technical precision in this work. The portrait is framed within an architectural trompe l'oeil setting, a common device in period portraiture to provide a sense of depth and formal gravitas.

Boullongne is shown in a three-quarter view, wearing a voluminous periwig and formal attire that reflects his status as Contrôleur Général des Finances. His hand rests upon a ledger, a detail that identifies his professional role. The drapery behind him and the stone-like frame contribute to the structured, formal composition. Wille employs a variety of hatching and cross-hatching techniques to render the textures of the fabric, the lace at the cuffs, and the smooth surface of the stone frame.

The lower portion of the print features an elaborate cartouche containing the subject's name and titles, flanked by decorative scrollwork. This inclusion of heraldic and textual elements is characteristic of the formal portrait prints produced for the French aristocracy and high-ranking officials of the era. The work demonstrates the meticulous approach to line and tone that defined Wille's reputation as a master of the burin. By focusing on the interplay of light and shadow, the artist creates a convincing sense of volume and presence. This print serves as a record of the visual language used to communicate authority and social standing in mid-eighteenth-century France.
