Andrea Mantegna's early study of antique sculpture moulded his whole life's work. He took great delight in modelling, in perspective, of which he made himself a master, and in chiaroscuro, or light and shade. Had his powers of invention and grace not kept pace with his skill, he would have been a stiff and formal worker; as it was, he carried the austerity of sculpture into painting, and his greatest work, the 'Triumph of Julius Caesar,' would have been better suited for the chiselled frieze of a temple than it is for the painted frieze of the hall of a palace. Yet he was a great leader and teacher in art, and the true proportions of his drawing are grand, if his colouring is harsh. I am happy to say that Mantegna's 'Triumph of Julius Caesar' is in England at Hampton Court, having been bought from the Duke of Mantua by Charles I. These cartoons, nine in number, are sketches in water-colour or distemper on paper fixed on cloth. They are faded and dilapidated, as they well may be, considering the slightness of the materials and their age, about four hundred years. At the same time, they are, after the cartoons of Raphael (which formed part of the same art collection of Charles I.), perhaps the most valuable and interesting relic of art in England. The series of the 'Triumph' contain the different parts, originally separated by pillars, of a long and splendid procession. There are trumpeters and standard bearers, the statues of the gods borne aloft, battering-rams and heaps of glittering armour, trophies of conquest in huge vases filled with coin, garlanded oxen, and elephants. The second last of the series, presents the ranks of captives forming part of the show, rebellious men, submissive women, and unconscious children--a moving picture. In the last of the series comes the great conqueror in his chariot, a youth in the crowd following him, carrying his banner, on which is inscribed Caesar's notable despatch, 'Veni, vidi, vici;' 'I came, I saw, I conquered.' Another of Mantegna's best pictures is in distemper--in which, and on fresco, Mantegna chiefly painted,--and is in the Louvre, Paris. It is the Madonna of Victory, so called from its being painted to commemorate the deliverance of Italy from the French army under Charles VIII., a name which has acquired a sardonic meaning from the ultimate destination of the picture. This picture--which represents the Virgin and Child on a throne, in an arbour of fruit and flowers, between the archangels, Michael and St Maurice, in complete armour, with the patron saints of Mantua and the infant St John in the front, and the Marquis Ludovico of Mantua and his wife, Isabella D'Este, kneeling to return thanks--was painted by Mantegna at the age of seventy years; and, as if the art of the man had mellowed with time, it is the softest and tenderest of his pictures in execution. A beautiful Madonna of Mantegna's, still later in time, is in the National Gallery.
