In a Florence library, a 1551 astronomy book held handwritten notes that went unnoticed for centuries; a historian recognised them as Galileos writing from around 1590

A historian in Florence has discovered handwritten annotations believed to be Galileo Galileis in a 1551 copy of Ptolemys Almagest. The discovery sheds light on Galileos early engagement with geocentric astronomy before he became a leading supporter of heliocentrism. The mathematical notes and an accompanying biblical passage offer a rare glimpse into his intellectual and personal life, demonstrating how forgotten marginalia can reveal fascinating insights into historys greatest minds.
