In January of 1548, Titian, now past seventy, was summoned to Augsburg, where Charles V. had convened the Diet of the Empire. He painted the portrait of Charles on the field of Muhlberg "in burnished armor-inlaid with gold, his arms and legs in chain mail, his hands gauntleted, a morion with a red plume, but without a visor, on his head. The red scarf with gold stripes--cognizance of the House of Burgundy--hung across his shoulders, and he brandished with his right hand a sharp and pointed spear. The chestnut steed, half hid in striped housings, had a head-piece of steel topped by a red feather similar to that of its master." Titian also painted, while at Augsburg, King Ferdinand, the brother of Charles, Queen Mary of Hungary, "Prometheus," "Sisyphus," "Ixion," and "Tantalus" at her request, besides many other pictures. Charles so honored Titian that once when the artist dropped his brush the emperor picked it up and handed it to him, saying that "Titian was worthy of being served by Cæsar." On a second visit to Augsburg Titian painted a portrait of Philip II. of Spain, the son of Charles. This was sent to Queen Mary of England, when Philip was her suitor, and quite won her heart, presumably more than the man himself when he afterwards became her husband. When Titian parted from his patron, Charles gave him a Spanish pension of five hundred scudi. He returned to Venice "rich as a prince instead of poor as a painter." Philip II. was as much a patron of art as his father, and was constantly soliciting paintings from Titian. It is best, probably, that most of us are worked to our utmost capacity, for work rarely kills people; worry frequently destroys both body and brain. For Philip he painted a "St. Margaret," now in the museum at Madrid; a "Danaë," where an old woman sits beside the couch and gathers Jupiter's golden shower in her apron; a "Perseus and Andromeda," the princess bound to a rock, and Perseus saving her; and a "Venus and Adonis," now at Madrid. For the enfeebled Emperor Charles he painted "The Grieving Virgin," now in the Madrid Museum, which represents the mother lamenting over the sufferings of the Saviour, and the "Trinity," now at Madrid, showing the Virgin interceding before the Father and Son for the imperial family,--a picture upon which the emperor used to gaze with intense feeling when he had retired to die in the Convent of Yuste. Thither he carried nine of Titian's paintings for his consolation. He died in 1558, with his eyes resting lovingly upon a picture of the emperor painted by Titian, and upon "The Trinity." "Christ appearing to the Magdalen" was sent to Queen Mary of Hungary.
