The Spiral Path: The Life of Fibonacci

In 12th-century Pisa, spice merchant Guglielmo Bonacci discovers his son's gift for numbers, fluency in languages and swordsmanship.

The father and son set sail across the Mediterranean, unknowingly charting a course that will alter the destiny of mathematics, trade, and science in Europe. But genius is never without enemies.

From the intrigue-filled courts of Palermo to the shifting sands of North Africa, Leonardo’s rise sparks suspicion. As he introduces revolutionary ideas in calculation and dares to publish Liber Abaci, powerful forces push back. His wife Cecilia becomes a target of the Inquisition.

In the face of persecution and betrayal, Leonardo finds unexpected allies: a visionary emperor, a devoted apprentice, and the quiet, unstoppable rhythm of the spiral that governs the world. Through danger and love, war and science, Leonardo pursues his true passion—decoding the divine patterns in nature.

Profuse in historical detail about the life of Fibonacci, John Broughton's THE SPIRAL PATH is a story of discovery and resilience.
