After the “Supper at Emmaus,” Caravaggio produced two more paintings for the Mattei brothers. The first was the unorthodox “St. John the Baptist” that today is in the Capitoline Museums in Rome and is a rather unabashed representation of a naked youth embracing a ram and lacking any conventional imagery. The second painting is the dramatic “Taking of Christ,” which was thought lost for centuries before being rediscovered in 1990 in the dining hall of the house of Jesuit fathers in Dublin, Ireland.
