David with the Head of Goliath. It portrays the biblical David as a youth, full-length, facing the spectator, holding the decapitated head of the giant Goliath by the hair. The peculiar characteristic of this canvas is that although the hero is represented as the stronger of the two, evidently victorious over the giant, at the same time he is paradoxically fragile and vulnerable
Papadopoulos reads the Guido Reni painting of David and Goliath — known to Jung from childhood — as a symbolic template for the Jung-Freud relationship, in which the younger, vulnerable victor nonetheless overcomes the towering elder.
