What is the full name of the person that thought they had purchased an oil sketch prepared by Velázquez?  Answer the above question based on the context below:  In 1692, the Neapolitan painter Luca Giordano  became one of the few allowed to view paintings held in Philip IV's private apartments, and was greatly impressed by Las Meninas. Giordano described the work as the "theology of painting", and was inspired to paint A Homage to Velázquez (National Gallery, London). By the early 18th century his oeuvre was gaining international recognition, and later in the century British collectors ventured to Spain in search of acquisitions. Since the popularity of Italian art was then at its height among British connoisseurs, they concentrated on paintings that showed obvious Italian influence, largely ignoring others such as Las Meninas.An almost immediate influence can be seen in the two portraits by Mazo of subjects depicted in Las Meninas, which in some ways reverse the motif of that painting. Ten years later, in 1666, Mazo painted Infanta Margaret Theresa, who was then 15 and just about to leave Madrid to marry the Holy Roman Emperor. In the background are figures in two further receding doorways, one of which was the new King Charles (Margaret Theresa's brother), and another the dwarf Maribarbola. A Mazo portrait of the widowed Queen Mariana again shows, through a doorway in the Alcázar, the young king with dwarfs, possibly including Maribarbola, and attendants who offer him a drink.  Mazo's painting of The Family of the Artist also shows a composition similar to that of Las Meninas. Francisco Goya etched a print of Las Meninas in 1778, and later used Velázquez's painting as the model for his Charles IV of Spain and His Family. As in Las Meninas, the royal family in Goya's work is apparently visiting the artist's studio. In both paintings the artist is shown working on a canvas, of which only the rear is visible. Goya, however, replaces the atmospheric and warm perspective of Las Meninas with what Pierre Gassier calls a sense of "imminent suffocation". Goya's royal family is presented on a "stage facing the public, while in the shadow of the wings the painter, with a grim...
