Sir Joshua painted two years later the beautiful but unhappy Mrs. Musters, whose son John married Mary Chaworth, Byron's first love. "The fine full-length of her as Hebe, with the eagle, still hangs at Colwich Hall. Another full-length, with a spaniel at her feet, painted in 1777, the year of her marriage, is at Petworth. It is interesting to compare the two, and note the wear and tear of five years in the reign of a queen of fashion." The eagle was a pet of Sir Joshua, kept in a yard outside the studio. In 1783, when Mrs. Siddons was the leading actress of the time, she sat to Reynolds. Taking her hand, he led her up to his platform with the words, "Ascend your undisputed throne: bestow on me some idea of the Tragic Muse." "On which," she said, "I walked up the steps, and instantly seated myself in the attitude in which the Tragic Muse now appears." He inscribed his name on the border of her drapery, saying, "I could not lose the honor this opportunity afforded me of going down to posterity on the hem of your garment." Sir Thomas Lawrence called this the finest portrait in the world of a woman, and Mrs. Jameson says, "It was painted for the universe and posterity." This picture was purchased, in 1822, by the first Marquis of Westminster, for nearly nine thousand dollars. Reynolds also painted Miss Kemble, her sister, "a very sweet and gentle woman." This year, 1784, a friendship of thirty years was severed by the death of Dr. Johnson. On his death-bed, he made three requests of Sir Joshua: never to use his pencil on Sundays; to read the Bible whenever possible, and always on Sundays; and to forgive him a debt of thirty pounds, which he had borrowed of him, as he wished to leave the money to a poor family. Reynolds was present at the funeral, when his friend was laid beside Garrick, in the south transept of Westminster Abbey. Reynolds said of his friend: "His pride had no meanness in it; there was nothing little or mean about him. "Truth, whether in great or little matters, he held sacred. From the violation of truth, he said, in great things your character or your interest was affected, in lesser things your pleasure is equally destroyed. I remember, on his relating some incident, I added something to his relation, which I supposed might likewise have happened: 'It would have been a better story,' says he, 'if it had been so; but it was not.' Our friend, Dr. Goldsmith, was not so scrupulous; but he said he only indulged himself in white lies, light as feathers, which he threw up in the air, and, on whomever they fell, nobody was hurt. 'I wish,' says Dr. Johnson, 'you would take the trouble of moulting your feathers.' "As in his writings not a line can be found which a saint would wish to blot, so in his life he would never suffer the least immorality or indecency of conversation, or anything contrary to virtue or piety, to proceed without a severe check, which no elevation of rank exempted them from.
