In the 15th and 16th centuries, the High Renaissance gave rise to a stylised art known as Mannerism. In place of the balanced compositions and rational approach to perspective that characterised art at the dawn of the 16th century, the Mannerists sought instability, artifice, and doubt. The unperturbed faces and gestures of Piero della Francesca and the calm Virgins of Raphael are replaced by the troubled expressions of Pontormo and the emotional intensity of El Greco.
