Flavio Biondo (Latin Flavius Blondus) (1392 – June 4, 1463) was an Italian Renaissance humanist historian. He was one of the first historians to use a three-period division of history (Ancient, Medieval, Modern) and is known as one of the first archaeologists. Born in the capital city of Forlì, in the Romagna region, Flavio was well schooled from an early age, studying under Ballistario of Cremona. During a brief stay in Milan, he discovered and transcribed the unique manuscript of Cicero's dialogue Brutus. He moved to Rome in 1433 where he began work on his writing career; he was appointed secretary to the Cancelleria under Eugene IV in 1444 and accompanied Eugene in his exile in Ferrara and Florence. After his patron's death, Flavio was employed by his papal successors, Nicholas V, Callixtus III and the humanist Pius II.
