In Erichthonius discovered by the daughters of Cecrops, vibrant colors dominate the canvas, showcasing a lush landscape filled with greenery. The figures of the daughters are depicted in dynamic poses, expressing surprise and curiosity. Erichthonius, a half-serpent figure, is at the center, drawing attention with his unusual form.

The background features a soft sky, enhancing the scene's mythical quality. Rubens employs oil on canvas to create this work, allowing for rich textures and deep colors. The composition is balanced, with the figures arranged in a triangular formation that guides the viewer's eye. The use of light and shadow adds depth, highlighting the emotional expressions of the characters.

The painting measures approximately 150 x 200 cm, making it a significant piece in size. Peter Paul Rubens, a leading figure of the Baroque period, often explored themes from mythology and history. This painting reflects his interest in dynamic movement and emotional expression. An interesting fact about this work is that it illustrates a lesser-known myth, showcasing Rubens' ability to bring obscure stories to life through his art.

Today, it is housed in the Museo del Prado, one of the most important art museums in Spain.
