Caravaggio
Michelangelo Merisi (Michele Angelo Merigi or Amerighi) da Caravaggio (, , ; 28 September 1571 – 18 July 1610) was an Italian painter active in Rome, Naples, Malta, and Sicily from the early 1590s to 1610. His paintings combine a realistic observation of the human state, both physical and emotional, with a dramatic use of lighting, which had a formative influence on Baroque painting.
Giulio Mancini
Giulio Mancini (21 February 1559 – 22 August 1630) was a seicento physician, art collector, art dealer and writer on a range of subjects. His writings on contemporary artists like Caravaggio and Annibale Carracci remain one of our earliest sources of biographical information; his "Considerazioni" being an important source on art in early 17th-century Rome.
