But returning to Marc' Antonio: having arrived in Rome, he engraved on copper a most lovely drawing by Raffaello da Urbino, wherein was the Roman Lucretia killing herself, which he executed with such diligence and in so beautiful a manner, that Raffaello, to whom it was straightway carried by some friends, began to think of publishing in engravings some designs of works by his hand, and then a drawing that he had formerly made of the Judgment of Paris, wherein, to please himself, he had drawn the Chariot of the Sun, the nymphs of the woods, those of the fountains, and those of the rivers, with vases, the helms of ships, and other beautiful things of fancy all around; and when he had made up his mind, these were engraved by Marc' Antonio in such a manner as amazed all Rome. After them was engraved the drawing of the Massacre of the Innocents, with most beautiful nudes, women and children, which was a rare work; and then the Neptune, with little stories of AEneas around it, the beautiful Rape of Helen, also after a drawing by Raffaello, and another design in which may be seen the death of S. Felicita, who is being boiled in oil, while her sons are beheaded. These works acquired such fame for Marc' Antonio, that his engravings were held in much higher estimation, on account of their good design, than those of the Flemings; and the merchants made very large profits out of them. Raffaello had kept an assistant called Baviera for many years to grind his colours; and since this Baviera had a certain ability, Raffaello ordained that he should attend to the printing of the engravings executed by Marc' Antonio, to the end that all his compositions might thus be finished, and then sold in gross and in detail to all who desired them. And so, having set to work, they printed a vast number, which brought very great profit to Raffaello; and all the plates were signed by Marc' Antonio with the following signatures, "R.S." for the name of Raffaello Sanzio of Urbino, and "M.F." for that of Marc' Antonio. Among these works were a Venus embraced by Love, after a drawing by Raffaello, and a scene in which God the Father is blessing the seed of Abraham, with the handmaiden and two children. Next were engraved all the round pictures that Raffaello had painted in the apartments of the Papal Palace, such as the Universal Knowledge, Calliope with the musical instrument in her hand, Foresight, and Justice; and then, after a small drawing, the scene which Raffaello had painted in the same apartment, of Mount Parnassus, with Apollo, the Muses, and the Poets; and also that of AEneas carrying Anchises on his back while Troy is burning, of which Raffaello had made the drawing in order to paint a little picture. After this they engraved and printed another work of Raffaello, Galatea in a car drawn over the sea by Dolphins, with some Tritons who are carrying off a Nymph.
