After an initial training with Goya, Rosario Weiss completed her education in Bordeaux with Pierre Lacour, from whom she learned the art of the portrait. This became her speciality upon her return to Madrid. The Duke and Duchess of San Fernando commissioned her to make a smaller copy and an engraving of the large courtly portrait that had been painted of them by the Murcian artist Rafael Tegeo. Weiss’s replica, believed until recently to be by Tegeo himself, shows the extraordinary quality of the works of this artist, subsidiary as they often were to those of her male colleagues.
