The culmination of a 15-year journey! After years of meticulous research, travel, and collaboration, Al-Idrisi and his team unveiled a work of genius that would stand unchallenged for centuries.

In this final chapter (Part 3), we reveal Al-Idrisi's monumental achievements:

The grand reveal: A massive silver planisphere and the accompanying book, "Nuzhat al-Mushtaq" (The Book of Roger).

His astonishingly accurate calculation of the Earth's circumference (37,000 km), which had less than a 10% error from the modern value.

The sophisticated scientific methods and global sources that made this accuracy possible.

Why "The Book of Roger" was the most detailed and accurate geographical text of its age.

This wasn't just a map; it was the pinnacle of scientific achievement in the 12th century.
