No little ability, likewise, has been shown in this profession by Giovan Battista Mantovano, a disciple of Giulio Romano; among other works, in a Madonna who has the Child in her arms and the moon under her feet, and in some very beautiful heads with helmet-crests after the antique; in two sheets, in which are a captain of mercenaries on foot and one on horseback, and also in a sheet wherein is a Mars in armour, who is seated upon a bed, while Venus gazes on a Cupid whom she is suckling, which has in it much that is good. Very fanciful, also, are two large sheets by the hand of the same master, in which is the Burning of Troy, executed with extraordinary invention, design, and grace. These and many other sheets by the same hand are signed with the letters "J.B.M." And no less excellent than any of those mentioned above has been Enea Vico of Parma, who engraved the well-known copper-plate of the Rape of Helen by Rosso, and also another plate after the design of the same painter, of Vulcan with some Loves, who are fashioning arrows at his forge, while the Cyclopes are also at work, which was truly a most beautiful engraving. He executed the Leda of Michelagnolo on another, and also an Annunciation after the design of Tiziano, the story of Judith that Michelagnolo painted in the Chapel, the portrait of Duke Cosimo de' Medici as a young man, in full armour, after the drawing by Bandinelli, and likewise the portrait of Bandinelli himself; and then the Contest of Cupid and Apollo in the presence of all the Gods. And if Enea had been maintained and rewarded for his labours by Bandinelli, he would have engraved many other beautiful plates for him. Afterwards, Francesco, a protege of the Salviati, and an excellent painter, being in Florence, and assisted by the liberality of Duke Cosimo, commissioned Enea to engrave the large plate of the Conversion of S. Paul, full of horses and soldiers, which was held to be very beautiful, and gave Enea a great name. The same Enea then executed the portrait of Signor Giovanni de' Medici, father of Duke Cosimo, with an ornament full of figures. He engraved, also, the portrait of the Emperor Charles V, with an ornament covered with appropriate Victories and trophies, for which he was rewarded by His Majesty and praised by all; and on another plate, very well engraved, he represented the victory that the Emperor gained on the Elbe. For Doni he executed some heads from nature in the manner of medallions, with beautiful ornaments: King Henry of France, Cardinal Bembo, Messer Lodovico Ariosto, the Florentine Gello, Messer Lodovico Domenichi, Signora Laura Terracina, Messer Cipriano Morosino, and Doni himself. He also engraved for Don Giulio Clovio, a most excellent illuminator, a plate of a S. George on horseback who is slaying the Dragon, in which, although it was, one might say, one of the first works that he engraved, he acquitted himself very well.
