At the core of the Christian faith is an image at once powerful and harrowing the figure Jesus on the Cross. Seeing Salvation Part 3 "The Cross" - describes the depiction of the crucified Christ, Christ on the Cross, and the shifting culture of sacrifice and redemption portrayed by these symbols. Throughout the centuries this image has come to symbolise different things to different people ...sometimes the battle standard of a conqueror, at others a man whose suffering has a deeply personal resonance. In this episode of Seeing Salvation, Neil MacGregor examines the various responses of artists to this defining moment...the passion of Christ.
