Fache eyed the naked man, and grunted.

"Early religion was based on the divine order of Nature. The goddess Venus and the planet Venus were one and the same. The goddess had a place in the nighttime sky and was known by many names—Venus, the Eastern Star, Ishtar, Astarte—all of them powerful female concepts with ties to Nature and Mother Earth."

Fache looked more troubled now, as if he somehow preferred the idea of devil worship.

Langdon decided not to share the pentacle's most astonishing property—the graphic origin of its ties to Venus. As a young astronomy student, Langdon had been stunned to learn the planet Venus traced a perfect pentacle across the ecliptic sky every four years. So astonished were the ancients to observe this phenomenon, that Venus and her pentacle became symbols of perfection, beauty, and the cyclic qualities of sexual love. As a tribute to the magic of Venus, the Greeks used her four-year cycle to organize their Olympiads. Nowadays, few people realized that the four-year schedule of modern Olympic Games still followed the cycles of Venus. Even fewer people knew that the five-pointed star had almost become the official Olympic seal but was modified at the last moment—its five points exchanged for five intersecting rings to better reflect the games' spirit of inclusion and harmony.
