ปกหนังสือปรัชญาคลาสสิกสไตล์มินิมอล

Minimalist classical book cover design in vertical format on a warm ivory parchment background. At the top center, the title is set in elegant, large dark navy serif typography across two lines: "[La Ciudad de Dios]". Centered below with generous spacing is a small gold phi symbol (φ). In the upper-middle area, a delicate, thin-line gold illustration shows a fortified circular heavenly city with 8 visible outer towers, crenelated walls, and compact classical buildings surrounding a central dome, emitting a soft vertical gold beam of light downward. In the lower-middle area, delicate thin dark navy line art depicts earthly classical ruins: the Roman Colosseum on the left, a classical temple with columns on the right, an arched ruin, and a broken fallen column in the foreground. At the bottom center, the author name is set in matching dark navy serif typography: "[San Agustín de Hipona]". Symmetrical composition, ample negative space, clean editorial balance, sacred philosophical aesthetic, no photographic textures or clutter.
