The print combines engraving and etching on laid paper, allowing Saint‑Aubin to render fine lines and subtle textures. The overlay of engraving on etched areas creates depth, while the intricate hatching defines the fabric, hair, and facial features, giving the portrait a three‑dimensional quality within the limited tonal range.

Augustin de Saint‑Aubin produced this work during the final years of the French Ancien Régime, a period when portrait prints circulated widely among literate audiences. The piece reflects the family's tradition of publishing images of cultural figures, contributing to the visual record of France’s literary elite in the late eighteenth century.
