A detailed nineteenth-century engraving by Ambroise Tardieu depicting the French Marshal Jean-Baptiste Jourdan in full military regalia.

This engraving by Ambroise Tardieu depicts Jean-Baptiste Jourdan, a prominent French military commander who served during the Revolutionary and Napoleonic Wars. Tardieu, a member of a well-known family of cartographers and engravers, demonstrates technical precision in this portrait. The work captures Jourdan in his formal military uniform, complete with epaulettes and the insignia of his rank. The subject is presented within a classic oval frame, a common convention for portraiture of the period, which directs the viewer's focus toward the sitter's expression and features.

Technically, the print relies on fine hatching and stippling to create tonal depth and texture. The contrast between the dark fabric of the uniform and the lighter areas of the face and sash is managed with controlled lines, typical of early nineteenth-century French printmaking. The inscription below the portrait identifies the subject as 'M. le Maréchal Jourdan, Pair de France', reflecting his status in the post-Napoleonic political order. The composition is balanced and restrained, adhering to the aesthetic values of the era. This print serves as a historical record of a figure who played a significant role in the military history of France. The clean, academic style of the engraving ensures that the focus remains on the likeness of the subject, providing a clear visual document of his appearance and rank. The paper shows the subtle signs of age, which adds to the character of the piece as a historical artefact. It is an example of the professional portrait engraving that was widely produced to document the lives of public figures during the nineteenth century.
