Why was Artemesia Gentileschi so obsessed with the biblical story of Judith beheading Holofernes that she painted five versions of it?
The painting you are referring to, "Judith and Her Maidservant
Holding the Head of Holofernes" was actually painted by Artemisia
Gentileschi, not Caravaggio. Gentileschi was an avid follower of
Caravaggio, known as a caravaggisti, and copied many of his
techniques in her own work.
