Perseus and Andromeda (Lemoyne)
Perseus and Andromeda (Lemoyne) refers to a painting by the French artist Jean-Baptiste Lemoyne II (1704-1778). It is not a single, universally known masterpiece, but rather the subject of Perseus rescuing Andromeda was a common theme in art throughout history. It is therefore plausible that Lemoyne created a painting, or potentially sculptures, depicting this mythological scene.
The story of Perseus and Andromeda is drawn from Greek mythology. Andromeda, daughter of King Cepheus and Queen Cassiopeia of Ethiopia, was chained to a rock as a sacrifice to a sea monster (often identified as Cetus) sent by Poseidon. Poseidon was angered by Cassiopeia's boast that Andromeda was more beautiful than the Nereids (sea nymphs). The hero Perseus, having slain Medusa, flew over Andromeda, fell in love with her, and rescued her by killing the monster. He subsequently married her.
Given the prevalence of the myth, any painting by Lemoyne titled "Perseus and Andromeda" would likely depict this pivotal moment of Perseus slaying the sea monster and freeing Andromeda. The style and artistic interpretation would be characteristic of Lemoyne's era (Rococo/Late Baroque). To confirm the existence and specifics of such a painting, one would need to consult art historical catalogues, museum collections databases, and scholarship dedicated to the works of Jean-Baptiste Lemoyne II.
