"Create a detailed and atmospheric background suitable for displaying portraits of four famous historical figures. The scene should have an ancient, timeless feel with a blend of classic and grand elements, like a museum or gallery, with soft, diffused lighting. The backdrop should be neutral, with elegant textures like aged stone or dark, polished wood, subtly decorated with historic artifacts or scrolls. Ensure the background is rich yet not overpowering, allowing the portraits to stand out prominently."  --ar 9:16
