Historical Byzantine Mosaic Portrait Generation Prompt

Use the uploaded image as the composition and identity reference. Preserve the subject’s pose, gesture, framing, facial likeness, and overall arrangement. Transform the photograph into an authentic sixth-century Byzantine mosaic inside the apse of a Ravenna-style basilica. Rebuild the entire image using thousands of individually visible hand-cut glass and stone tesserae with irregular edges, dark grout, and slightly varied angles. Use a flat gold-leaf mosaic background with no realistic depth and place a simple golden halo behind the subject’s head. Adapt the figure into frontal Byzantine stylization with enlarged solemn eyes, simplified facial forms, and clothing rendered as graphic folds outlined in dark tiles. Use a limited palette of gold, lapis blue, oxblood red, ivory, and charcoal. Make the mosaic appear genuinely ancient, with cracked tiles, faded areas, missing sections exposing rough plaster, and soft raking light creating uneven reflections across the gold surface. Highly detailed historical mosaic texture, authentic handmade imperfections, aged basilica wall, museum-quality Byzantine artwork. Negative prompt: modern digital painting, smooth tiles, perfect symmetry, realistic 3D depth, glossy CGI, cartoon, anime, clean new wall, modern clothing details, text, logo, watermark. Do not place any text or website inside the artwork. Prompt credit: (http://www.prompteg.com) — external only, do not render it in the image.
