unlike the tmingand crowded tympanum of saint-lazare at autun whose subject was the last judgment in all its terrifying detail, here, we have the promise of salvation and a serenity and a majesty and above all, an approachable humanity that anites thsculpture here. we see in them the very embodiment of the mid-12th century humanism that is so prevalent in the school of chartres at this very time. one exciting thing at chartres is you can move from the west front to the north transept and change completely the sense of style in the sculpture. there's a change in the attitude towards the human body. these figures are now freer and seem to move. they have animated facial expressions. the drapery falls around the bodies and reveals it in its contours. we've got old testament kings and prophets. all of these emphasize salvation through sacrifice. abraham, for instance, is preparing to sacrifice his son isaac, as god commanded him. he looks up at the angel who orders him to substitute the ram. both the north and south transept portals belong to the new cathedral, built after the 1194 fire.
