In short

The landmark Renaissance scientific volume surpassed expectations at Christie's New York after being consigned by a California collector who acquired it in 2014. Authored by Queen Elizabeth I's royal physician, the work revolutionized scientific methodology by prioritizing experimental validation over prevailing scholastic tradition. To substantiate his revolutionary planetary claims, the author used a small spherical magnet called a terrella to mirror global forces on a miniature scale. The sale reflects continued high valuation for foundational texts that established early modern physics.
