Cavalier d'Arpin
Borghese was a discriminating collector but notorious for extorting and even stealing pieces that caught his eye - he, or rather his uncle Pope Paul V, had recently imprisoned Giuseppe Cesari, one of the best-known and most successful painters in Rome, on trumped-up charges in order to confiscate his collection of a hundred and six paintings, which included three of the Caravaggios today displayed in the Galleria Borghese ("Boy Peeling Fruit", "Young Sick Bacchus", and "Boy with a basket of Fruit"). They joined the Caravaggios that the Cardinal already possessed, including a "Saint Jerome" and the "Madonna and Child with St. Anne" (the "Grooms' Madonna").
