Design an ornate stained glass window that would be found in a medieval castle's library. The central image is that of a wise old sage in flowing robes, holding a grand tome, symbolizing knowledge and learning. Around him are various heraldic symbols and creatures that represent different fields of medieval scholarship, such as alchemy, astronomy, and philosophy. The background features an intricate lattice of interlocking geometric patterns and Gothic arches, with a color scheme of rich burgundies, deep forest greens, and muted golds. The sunlight streams through the glass, casting an ambient glow that seems to animate the figures and symbols. The window is crafted in a wide 16:9 aspect ratio to display the splendor and wisdom of the medieval era.
