A stunning oil painting of a historical scene featuring a naked mermaid lounging on a rocky shore, her shimmering scales reflecting the sunlight. The background showcases a tranquil sea with gentle waves, bordered by lush greenery. The mermaid has flowing, wavy hair adorned with sea flowers, and her expression embodies both serenity and allure. The style should evoke the romanticism of the 19th century, reminiscent of the works of artists like John William Waterhouse, with rich textures and vibrant colors that bring the underwater world to life.
