David with the Head of Goliath (Caravaggio, Vienna)
David with the Head of Goliath, c. 1607, in the Kunsthistorisches Museum Gemäldegalerie, Vienna, is a painting by the Italian artist Caravaggio (1571–1610). Peter Robb believes it to have been acquired by the conde de Villamediana in Naples between 1611 and 1617, as Giovanni Bellori records Villamediana as having returned to Spain with a half-figure of David by Caravaggio. Caravaggio also treated this subject in a work currently in the Galleria Borghese, Rome, and in an early work dated c. 1600 in the Prado in Madrid. The exact moment depicted appears  to be that referred to in I Samuel 17:57: "When David came back after killing the Philistine, Abner took him and presented him to Saul with the Philistine's head still in his hand." The pose is a usual one for the episode, showing David striding in triumph with the head in his hand. In the Borghese version this has changed to an unconventional frontal presentation of the head toward the viewer, who is thereby placed in the position of Saul. The painting can be compared with the "David with the Head of Goliath" in the Galleria Borghese, which dates  from either 1607 or 1609–10. The two are very similar—Caravaggio frequently explored a subject in multiple variations, most notably his many versions of John the Baptist—but the Vienna painting is less dark in mood, the David more triumphant than the introspective and oddly compassionate David of the Borghese, and the head of Goliath, widely accepted as a self-portrait in the Borghese work, is more generic. The model for David in both versions appears to be a more mature version of the pubescent Cupid of "Amor Vincit Omnia" and the Capitoline and Pamphilij "John the Baptist", all painted  around 1602. The model for these works has been identified by some, most notably Peter Robb, as Cecco, a boy known to have been Caravaggio's servant in Rome in the early 17th century and believed by Robb to be identical with Cecco del Caravaggio, an artist active in Rome in the period 1610–1625 and painting very much in Caravaggio's manner. There is no record of Cecco having been with Caravaggio after the artist's flight from Rome in 1606.
