The painting features a nude figure of Patriarch Jacob, depicted in a classical pose. The colors are warm, with soft flesh tones contrasting against a muted background. The setting is minimal, focusing attention on the figure itself.

The artist captures the anatomy with careful attention to detail, showcasing the musculature and form. This study is executed in oil on canvas, allowing for rich texture and depth. The brushwork is precise, highlighting the contours of the body. The dimensions are approximately 50 x 70 cm, making it a manageable size for study.

The work serves as a preparatory piece for a larger composition. Józef Simmler was a Polish artist known for his academic approach to painting. This nude study was created as a preparatory work for his larger painting, ‘The Immaculate Conception of the Blessed Virgin Mary’. It reflects the artist's commitment to the study of human anatomy and classical forms.

Simmler's works often combine religious themes with a strong emphasis on the human figure.
