Prompt
"Create an image of a historic, formal gathering of bishops in a grand, ornate hall with columns and arches, set in the 5th century. The scene should depict the Council of Chalcedon, with approximately 520 bishops seated in a semi-circle, engaged in discussion and deliberation. The dominant colors should be rich, muted tones such as gold, crimson, and dark wood. Incorporate subtle hints of the Byzantine Empire's architecture and decor. Convey a sense of gravity, importance, and intellectual debate, reflecting the council's significance in defining orthodox Christology and the nature of Christ."
