If we wish to find some explanation for the splendid colouring that makes the masterpieces of Rubens the delight of every unprejudiced eye, we may surely be content to remember that he saw Venice with the enthusiastic eye of twenty-three in the year 1600. Even to-day when Venice, vulgarised to the fullest extent that modern ingenuity can accomplish, has become no more than a remnant most forlorn of what it was, it is one of the world's wonder cities. When the seventeenth century was opening its eventful pages, the memory of wonderful achievements was upon the great city of the Adriatic, it was still a power to be reckoned with. The season of pageants had not passed, and the luck that seemed destined to accompany Rubens throughout his career was in close attendance upon him here. The Duke of Mantua. Vincenzo Gonzaga, saw some of his work, and was so struck by its quality that he sent for the young painter. The man seemed worthy of his creations, and the Duke promptly offered him a position in his suite, an offer too good to be declined. Thereafter the sojourn in Venice was a short one. Mantua, Florence, and Genoa were visited in turn, and in Mantua, after some months travelling to and fro, the Court settled down, and Rubens was enabled to study the splendid collection of works that the city's rulers had collected. In the late summer of the following year Rubens would seem to have visited Rome, where he faced the terrible heat without any ill effect and devoted himself with untiring energy to a study of the work that is to be seen there and nowhere else. It would appear that he was well received by the leading artists of the day, that he made a friend of Caravaggio, and he was soon commissioned to paint an altar-piece for the Church of the Holy Cross of Jerusalem. The work, done in three parts, is now we believe in the possession of the French Government, and is to be seen in Grasse or one of the neighbouring towns of the Mediterranean littoral. When Rubens' leave of absence expired--it must not be forgotten that he was in the service of Mantua's ruler, and was not his own master--he returned to the north, where the Duke would seem to have employed him for a time as an art expert. We may imagine that politics and art were closely connected, and that Rubens soon knew responsibility in connection with both. The work must have been very well done in each case, for rather more than a year later, when it became necessary in the interests of Mantua's political position to send a message to the King of Spain, Rubens was the chosen envoy.
