Caravaggio possessed a very irascible and roving disposition. At the height of his popularity at Rome, he got into a quarrel with one of his own young friends, in a tennis-court, and struck him dead with a racket, having been severely wounded himself in the affray. He fled to Naples, where he executed some of his finest pictures, but he soon got weary of his residence there, and went to Malta. Here his superb picture of the Grand Master obtained for him the Cross of Malta, a rich gold chain, placed on his neck by the Grand Master's own hands, and two slaves to attend him.
