The book delves deeply into the origins and philosophical underpinnings of Ancient Greek architecture, specifically focusing on the structural and metaphysical aspects of the Tholos of Delphi. It explores how the Doric order and its tectonic logic form a foundational aspect of European architecture, tracing back to the Hellenic roots. The author presents architecture not merely as a technical or aesthetic pursuit but as a rational and structural logic that embodies a universal language of geometry and mathematics. This narrative intertwines the examination of historical constructs with modern interpretations, revealing how ancient forms, styles, and principles remain relevant and influential. Interspersed with personal reflections and dialogues inspired by Platonic methodology, the text provides a holistic view of the discipline, capturing both the rigor of architectural science and its broader cultural, ethical, and philosophical implications.
