The story of Gerusalemme Liberata is based upon Tasso's epic poem of the same name.
As the crusaders reach the city of Jerusalem, two of the Christian leaders kneel in the foreground, both in Classical armor with garments of red, blue and yellow. The younger man is presumably Godfrey of Bouillon. Other mounted men in gray armor are seen behind. Rising in the background on the right are the walls of Jerusalem.
