Medieval mystery unlocked: The Light of Ages by Seb Falk

From Express:

THE MEDIEVAL knack for stories and myths has created some of the world's most sought after mysteries, pushing scores of the Middle Ages' most groundbreaking scientific achievements from the history books, an historian told Express.

Religious myths adorn the Medieval period. Things like the Shroud of Turin have captured the imaginations and speculation of academics, religious figures and history buffs the world over. Yet, it is so-called mysteries like the Shroud that, in fact, have quickly overshadowed the true pioneering discoveries that were characteristic of the Middle Ages, according to Dr Seb Falk, a Medieval historian at the University of Cambridge. Science boomed in the period that is generally accepted to run from the 5th to the 15th century.  There was a whole slew of inventions that we still use today.

A spellbinding journey through the life of an English monk, an age of discovery and the mysteries of the medieval mind

The Middle Ages were a time of wonder. They gave us the first universities, the first eyeglasses and the first mechanical clocks as medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky. In this book, we walk the path of medieval science with a real-life guide, a fourteenth-century monk named John of Westwyk - inventor, astrologer, crusader - who was educated in England's grandest monastery and exiled to a clifftop priory. Following the traces of his life, we learn to see the natural world through Brother John's eyes: navigating by the stars, multiplying Roman numerals, curing disease and telling the time with an astrolabe. We travel the length and breadth of England, from Saint Albans to Tynemouth, and venture far beyond the shores of Britain. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy and the Persian polymath who founded the world's most advanced observatory.An enthralling story of the struggles and successes of an ordinary man and an extraordinary time, The Light Ages conjures up a vivid picture of the medieval world as we have never seen it before.
