Giulio Romano (1499?-1546), Italian painter and architect in the Mannerist style. He was born Giulio Pippi in Rome and became the chief pupil of the Italian painter Raphael, whom he assisted in many of the latter's finest works. At Raphael's death he completed the frescoes Battle of Constantine and Apparition of the Cross in the Vatican Palace, Rome. He inherited a portion of Raphael's wealth, including his works of art, and succeeded him as head of the Roman school.

About 1524, Giulio accepted the invitation of Federigo Gonzaga, ruler of Mantua (Mantova) and patron of the arts, to carry out a series of architectural and pictorial works. The drainage of the marshes surrounding the city and its system of protection from the inundations of the Po and Mincio rivers attest to Giulio's skill as an engineer; his genius as an architect found scope in the planning and construction of the Palazzo del Tè, the cathedral, the streets, and a ducal palace.

Among his works of this period are the frescoes Psyche,Icarus, and Fall of the Titans, in the Tè palace. In Bologna, he designed the facade of the Church of San Petronio. Among the best of his works is Martyrdom of Saint Stephen (San Stefano, Genoa).
