Giovanni Baglione, Italian painter and historian of art (b. 1566)
Giovanni Baglione (1566 – 30 December 1643) was an Italian Late Mannerist and Early Baroque painter and art historian. He is best remembered for his acrimonious and damaging involvement with the slightly younger artist Caravaggio and his important collection of biographies of the other artists working in Rome in his lifetime, although there are many works of his in Roman churches and galleries and elsewhere.
