query: What is the significance of temples in ancient Greek and Roman architecture, specifically regarding their design and lighting?
answer: The design and lighting of ancient Greek and Roman temples, particularly whether they were hypaethral (open to the sky) or cleithral (covered), was a significant architectural feature.  The debate surrounding hypaethral temples involved discussions of how they were lit, the challenges of drainage in a rainy climate, and alternative methods of interior lighting.
