Portrait of Baldassare Castiglione by Raphael The period known as the High Renaissance roughly spans the four decades from 1490 to the sack of Rome in 1527. It represents the accepted apogee of Renaissance art - the period when the ideals of classical humanism were fully implemented in both painting and sculpture, and when painterly techniques of linear perspective, shading and other methods of realism were mastered.
