The Trental Mass for Berthal de Haze

Leys utilizes chiaroscuro to model the figures, allowing a narrow beam of light from a left‑hand window to illuminate the kneeling woman while the surrounding space recedes into shadow. The handling of oil paint emphasizes the texture of fabrics and the atmospheric depth, characteristic of the artist’s transition toward a more realistic rendering of light and form.
