A macro photograph of a peacock feather lying on an old, dusty book in a dimly lit Gothic library. The feather displays a rich combination of deep blues, iridescent greens, and hints of gold, muted by the dim light. Tiny dust particles on the feather and book add intricate texture to the image. The background is a softly blurred mix of ancient leather-bound books and shadowy bookshelves, creating a mysterious bokeh effect that enhances the feather's striking beauty in a gothic setting. The composition centers on the eye pattern of the feather, with sharp focus on the detailed structures and muted colors. 8k, high resolution details,  ultra detailed texture, gothic bokeh background, studio photo quality.
