Lorenzo Valla Exposes Donation of Constantine
The Italian humanist philologist proved, through close analysis of Latin vocabulary, historical anachronisms, and impossible legal terms, that the Donation of Constantine, the document purportedly granting the papacy temporal authority over all of western Europe, was an eighth-century forgery. The method was as revolutionary as the conclusion: linguistic evidence alone had overturned a political foundation of medieval Christendom. Textual criticism had become a weapon capable of toppling centuries of authority.
Eleven African Captives Landed at Lagos
A Portuguese caravel returned to Lagos with the first recorded consignment of sub-Saharan African captives specifically acquired as slaves. Prince Henry took his share and paid his share of papal benediction. Over the next sixty years the trickle would become a stream, then a river, then the Middle Passage. A papal bull soon granted Portugal the right to enslave non-Christians, providing the legal framework for the Atlantic slave trade.
Alfonso V Conquers Naples
The Aragonese king-poet entered Naples through an aqueduct, took the Angevin throne, and united Sicily, Sardinia, and southern Italy under one crown for the first time in centuries. His court became an early Italian Renaissance center where Catalan, Neapolitan, and Latin mingled over shared humanist manuscripts. His court hosted Lorenzo Valla, who proved the Donation of Constantine a forgery, undermining papal claims to temporal authority.
Alfonso the Magnanimous Enters Naples
The Aragonese king formally entered Naples under a triumphal arch designed by Renaissance architects. The arch still stands, a marble monument to a Catalan king's Italianization. Alfonso's court became a center of Latin and Greek learning, hosting Lorenzo Valla who would soon prove the Donation of Constantine a forgery. His patronage made Naples a Renaissance center rivaling Florence, though the cultural flowering would not survive his dynasty.
