The sketch features Queen Jadwiga and Jaśko of Tęczyn, depicted in a moment of solemnity. The figures are rendered with a focus on their expressions and attire, showcasing the historical context. The colors are muted, primarily using earth tones that evoke a sense of gravity.

The background is minimal, directing attention to the figures and their interaction. This artwork is a preparatory sketch, likely created with pencil or ink on paper. The lines are fluid, suggesting movement and emotion, while the details in the clothing hint at the period's fashion. The dimensions are approximately 25 x 35 cm, making it a manageable size for a study piece.

The sketch serves as a foundation for the larger painting titled 'Queen Jadwiga’s Oath'. Józef Simmler was a Polish artist known for his historical and portrait works. This sketch is significant as it represents the initial concept for a larger painting, emphasizing the importance of Queen Jadwiga in Polish history. An interesting fact is that Jadwiga was the first female monarch of Poland, and her reign is celebrated for its cultural and political impact.

Simmler's work reflects the Romantic style, focusing on emotional depth and historical narrative.
