Born Antonio Allergi, was one of the most important painters of the High Renaissance in Italy. He worked in Rome, Parme and in his native city. He was probably the pupil of Francesco Bianchi Ferrari, but was deeply influenced by the work of Andrea Mantegna and Leonardo da Vinci, and later also came Raphael and Michelangelo. Correggio became a pioneering master of illusionistic painting by trying to achieve the best possible expression of lightness and grace. He employed tone and colour to counterbalance his forms, thereby developing innovative effects of light and shadow. He created superb three-dimensionality by means of foreshortening and overlapping; and used lighting along with the aligning diagonals to create a depth of field that he incorporated into the events depicted. His works include The Vision of st. John the Evangelist, 1522, Adoration of the Shepard's, 1528, and Jupiter and lo, 1531.
