Masaccio Paints the Brancacci Chapel
A twenty-four-year-old Tuscan named Tommaso Cassai began frescoing a side chapel in Florence's Santa Maria del Carmine. His figures cast shadows; Adam and Eve wept with real anguish. Young painters, including a boy named Michelangelo, would later climb the scaffolding to study them as if the future lived there. His single-point perspective and naturalistic lighting transformed flat medieval fresco into convincing three-dimensional space, inventing Renaissance visual language.
Zheng He's Seventh Voyage Planned
The Xuande Emperor, son of Yongle, hesitantly authorized one more treasure voyage against the wishes of his Confucian court. It would sail in 1431 and be the last. The Chinese state was withdrawing from oceanic engagement just as Portuguese caravels were beginning their systematic southward push. The interval reflected fierce bureaucratic resistance from Confucian officials who regarded the voyages as ruinous extravagance.
Battle of Valmontone Between Rival Italian Condottieri
Braccio da Montone, the most feared mercenary in Italy, died in an inconclusive clash against forces loyal to Naples. His death rebalanced the peninsula's mercenary market and left the Sforza clan as the dominant military brokers, a position that would put them on the throne of Milan a generation later.
University of Louvain Founded
Duke John IV of Brabant chartered a new university at Louvain in the Low Countries. It would eventually house Erasmus, produce the Complutensian Polyglot Bible's Flemish counterparts, and become a theological battleground during the Reformation. Its medieval establishment anchored Low Countries scholarship for five centuries. It grew into one of northern Europe's most important centers of learning, attracting students across the Low Countries and Rhineland.
Battle of Maclodio
Francesco Bussone da Carmagnola led Venetian forces to a decisive victory over Milan in Lombardy. He captured ten thousand Milanese prisoners and released them, a condottiere courtesy that Venice would later interpret as treason. Carmagnola's eventual execution would expose the dangerous relationship between Italian cities and their hired commanders. Carmagnola's leniency was typical of condottiere warfare but aroused suspicion of collusion among his Venetian employers.
