Vieira Lusitano lived admired and honoured, to a venerable age, eighty-four; and his constant heroine, the Lady Agnes, also reached a good old age, and shared prosperity which could hardly have been real, or of any value, without her. She died at Mafra in 1775, and from the day of her death he never again touched a pencil. To the last, says Cyrillo, he idolised her memory; and, no doubt, the strength of his affection for her was the governing motive of his publication of their strange history, five years after her decease, and but three before his own. Both his own portrait and hers were often introduced into his paintings. Many of his works perished in the earthquake, with the temples and mansions they adorned. He particularises, as thus destroyed, "his grand picture of the Martyrs--the inestimable portrait of the first Patriarch of Lisbon, Don Thomas Almeida," (who figures as an important influence, for and against him, in the narration of his love adventure;) "the portraits of the Royal Children, and that sublime idea," (the words are his own,) "the Meeting of the Blessed Mother with her Son, after her assumption--the Death of Moses--Pluto and the Court of Hell listening to the suit of Orpheus." He says he designed the last-named performance as an allegorical plea for the restoration of his wife, to whom the convent was a hell. In another composition, which he calls "a stupendous work," and which was also demolished--Perseus exhibiting the Gorgon's head to Phineus--he represented his own effigy as that of the Greek hero, and the image of his cloistered wife, as a winged Victory, hovering over him, and about to drop a laurel wreath on his helm, &c.
