Focus on The Inspiration of Saint Matthew and explain the abstract.
The Inspiration of Saint Matthew (1602) is a painting by the Italian Baroque master Michelangelo Merisi da Caravaggio. Commissioned by the French Cardinal Matteo Contarelli, the canvas hangs in Contarelli chapel altar in the church of the French congregation San Luigi dei Francesi in Rome, Italy.  
It is one of three Caravaggio canvases in the chapel: hanging between the larger earlier canvases of The Martyrdom of Saint Matthew, and The Calling of Saint Matthew. This was not an easy commission for Caravaggio, and at least two of the three paintings had to be either replaced or repainted to satisfy his patron, the Cardinal Del Monte.
