The Nymph Egeria Dictating to Numa Pompilius the Laws of Rome is a painting created by Spanish artist Ulpiano Checa in 1883. It depicts the mythological scene of Numa Pompilius, the second king of Rome, receiving divine guidance from the nymph Egeria regarding the establishment of Roman religious practices.

In this painting, Numa and Egeria are shown in a secluded landscape, with the nymph sitting on a rock and dictating to Numa. The setting is peaceful, with a gentle stream running through the background, emphasizing the mystical connection between the two figures. Ulpiano Checa's use of light and shadow creates an ethereal atmosphere that underscores the divine nature of their interaction.

The painting showcases Checa's skill in rendering human forms and capturing the emotional intensity of his subjects. Numa's expression is contemplative, while Egeria's gaze is serene and wise. The composition is well-balanced, with the figures positioned symmetrically to create a sense of harmony.

The Nymph Egeria Dictating to Numa Pompilius the Laws of Rome reflects Checa's interest in mythological themes and his fascination with the historical development of Roman civilization. This painting exemplifies his ability to blend artistic sensibility with historical accuracy, resulting in an evocative and compelling portrayal of a pivotal moment in Roman legend.

Unfortunately, Ulpiano Checa is not as widely known today as some of his contemporaries, which may be due to the fact that many of his works were lost or destroyed during the Spanish Civil War. Nonetheless, The Nymph Egeria Dictating to Numa Pompilius the Laws of Rome remains a testament to his artistic talent and serves as an important representation of late 19th-century Spanish painting.
