《上帝之城》古典风格封面

A minimalist, elegant vintage book cover design on warm ivory textured paper for {argument name="book title" default="La Ciudad de Dios"}. Center the title near the top in large classical serif typography, dark navy blue, with refined spacing and a literary feel. Directly below it, place 1 small eight-point star in gold. In the upper middle, illustrate a heavenly walled city floating on clouds, drawn as delicate gold line art: a symmetrical sacred city with 1 central domed cathedral, many clustered towers, spires, walls, and gates, surrounded by soft clouds, with radiant sunburst lines spreading outward behind it. From the central gate of the celestial city, send down 1 vertical column of thin golden light beams toward the lower half of the cover. In the bottom third, depict an earthly ancient Roman landscape in fine blue-gray ink line art: 5 main architectural ruins and monuments arranged horizontally, including a long arcade on the left, a classical temple with columns near left-center, a domed building in the middle, a bell tower and surrounding ruins near right-center, and a colosseum-like ruin on the far right, plus a broken fallen column drum in the right foreground and sparse shrubs and ground texture. Keep the composition airy, symmetrical, and contemplative, with abundant negative space between heaven and earth. Place the author name {argument name="author name" default="SAN AGUSTÍN DE HIPONA"} centered at the bottom in spaced small caps serif, dark navy blue. Use only 3 visible text elements total: the title, the author name, and no subtitle. Palette limited to ivory, gold, and dark navy blue, with precise engraved linework and a sacred, timeless, classical theological mood.
