Esquisse pour quatre personnages drapés 

This pencil sketch by Narcisse-Virgilio Diaz, titled "Esquisse pour quatre personnages drapés" is a preliminary study for a larger composition. It shows four figures, likely women, draped in flowing garments, sitting in a group. The artist uses loose, gestural lines to capture the movement and form of the figures, suggesting a sense of spontaneity and immediacy. The sketch is an example of Diaz's interest in capturing the beauty of the human form and the movement of fabric. This preliminary study, also known as an "esquisse" in French, is a fascinating glimpse into the artist's creative process.
