 The masterpiece in Rome is a "twin" of a second artwork on the same subject, David and Goliath, as reported in the inventory of the Galleria Borghese dated 1693, where is found that one was located in the first room, and the other in the fourth room.According to his biographer Bellori, the artwork had been commissioned to Caravaggio by Cardinal Scipione Borghese in 1606, a work that is possibly performed on a double easel, thus generating two twin masterpieces.The biographical interest of the painting adds another layer of meaning to an already complex work, David and Goliath standing for Christ and Satan and the triumph of good over evil in orthodox Christian iconography of the period, and also as the cold-hearted beloved who "kills" and his lover according to contemporary literary conceit.
