Sir Joshua was now elected mayor of Plympton, his native town, an honor which he greatly prized; and received the degree of D. C. L. from Oxford University. Oliver Goldsmith had died, and on the day of his death Sir Joshua did not touch a pencil, "a circumstance the most extraordinary for him," says Northcote, "who passed no day without a line." He acted as executor for his dead friend, and found, to his amazement, that his debts were ten thousand dollars.

Reynolds was as ever the centre of a charming circle. Miss Burney, the author of "Evelina," liked his countenance and manners; the former she pronounced "expressive, soft, and sensible; the latter, gentle, unassuming, and engaging." Hannah More, too, was greatly pleased with the distinguished painter.

"Foremost among the beauties of this brilliant time," says Leslie, "was Sir Joshua's pet in childhood, now the irresistible young queen of ton, Georgiana, Duchess of Devonshire. She effaced all her rivals, Walpole tells us, without being a beauty. 'Her youth, figure, glowing good-nature, sense, lively modesty, and modest familiarity make her a phenomenon.' The young duchess was now sitting to him in the full flush of her triumph as arbitress of fashion, the most brilliant of the gay throng who danced and played the nights away at the Ladies' Club, masqueraded at the Pantheon, and promenaded at Ranelagh. Marie Antoinette herself had scarcely a gayer, more devoted, and more obsequious court. It was this beautiful young duchess who set the fashion of the feather headdresses, now a mark for all the witlings of the time. Sir Joshua has painted her in her new-fashioned plumes, in the full-length now at Spencer House....

"Another beautiful sitter of this year was Eliza, the youthful wife of Richard Brinsley Sheridan. The young couple were now emerging from the first difficulties of their married life. Her exquisite and delicate loveliness, all the more fascinating for the tender sadness which seemed, as a contemporary describes it, to project over her the shadow of early death; her sweet voice, and the pathetic expression of her singing; the timid and touching grace of her air and deportment, had won universal admiration for Eliza Ann Linley. From the days when, a girl of nine, she stood with her little basket at the pump-room door, timidly offering the tickets for her father's benefit concerts, to those when in her teens she was the belle of the Bath assemblies, none could resist her beseeching grace. Lovers and wooers flocked about her; Richard Walter Long, the Wiltshire miser, laid his thousands at her feet....

"Nor had she resisted only the temptation of money; coronets, it was whispered, had been laid at her feet as well as purses. When she appeared at the Oxford oratorios, grave dons and young gentlemen commoners were alike subdued. In London, where she sang at Covent Garden in the Lent of 1773, the king himself was said to have been fascinated as much by her eyes and voice as by the music of his favorite Händel. From all this homage Miss Linley had withdrawn to share love in a cottage with Sheridan at East Burnham, after a runaway match in March, 1772, and after her husband had fought two duels in her cause with a Captain Matthews. When she began to sit to Sir Joshua, Richard Brinsley Sheridan was only known as a witty, vivacious, easy-tempered, and agreeable young man of three and twenty, with nothing but his wits to depend on; but, before the picture was finished, he was famous as the author of 'The Rivals.'"

Sir Joshua painted Mrs. Sheridan as St. Cecilia. "She had a way of gathering little children about her, and singing their childish songs, with 'such a playfulness of manner, and such a sweetness of look and voice,' says one, in describing her so engaged, 'as was quite enchanting.'... Mrs. Sheridan was gentleness personified, and sang without pressing; but her husband, proud of her as he was, would never allow her to sing in public after their marriage, and was even chary of permitting her to delight their friends with her sweet voice in private. She was the lovely model for the Virgin in Reynolds's 'Nativity,' for which the young Duke of Rutland paid him six thousand dollars, an unexampled price for an English picture at that time. It was burnt at Belvoir Castle. She died a few years later, living long enough to witness her husband's great success, and not long enough to see him overwhelmed with debts, partly the result of drink."

In 1780, Sir Joshua painted the ladies Maria, Laura, and Horatia Waldgrave, grand-nieces of Horace Walpole. "He never had more beautiful sitters," says Leslie; "and in none of his pictures has he done more justice to beauty. Their bright faces are made to tell with wonderful force, by the white dresses and powdered têtes worn by all three. They are sitting round a work-table. Lady Laura, in the centre, winds silk on a card from a skein held by Lady Horatia; while Lady Maria, on the right, bends over her tambouring frame. The action admits of a natural arrangement of the heads, in full-face, three-quarters, and profile; and it is impossible to conceive an easier, prettier way of grouping three graceful, high-bred young ladies." At this time, all three of these young ladies were in sorrow. The young Duke of Ancaster, to whom Horatia was betrothed, had just died suddenly, and two prominent lords to whom the other sisters were engaged had broken their promises. Lady Maria married, four years later, the Earl of Euston; Laura, her cousin, Lord Chewton; and Horatia, Lord Hugh Seymour.

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.
