Giovanni Baglione (Italian: [d͡ʒoˈvan.ni baʎˈʎoː.ne]; 1566 – 30 December 1643) was an Italian Late Mannerist and Early Baroque painter and art historian. Although a prolific painter, Baglione is best remembered for his encyclopedic collection of biographies of the other artists working in Rome during his lifetime, and particularly his acrimonious relationship with the slightly younger artist Caravaggio through his art and writings.
