Lawrence was commissioned to paint for Windsor Castle a commemoration gallery of those who had restored the Bourbons. The sitters chosen were the Emperor of Russia, the King of Prussia, Blücher, and Hetman Platoff. The portraits were painted, and at about the same time, Wellington and Metternich sat to the painter. Lawrence recovered all the ground he had lost, and gained fresh honours in rapid succession. In the year of Waterloo he painted the portrait of the Prince Regent, who knighted him; in 1817 he painted at Claremont the portrait of the Princess Charlotte. To these years his biographers trace the beginning of his relations with Mrs. Wolfe, wife of a diplomat accredited to this country. Cunningham refers to her as the wife of a Danish Consul, Mr. Knapp says she was the wife of the German Ambassador, but the point is not worth investigating. Suffice it she was a clever, attractive woman, separated from her husband, and the artist seems to have established with her intimate but platonic relations. He was devoted to her, but, then, he had a very susceptible heart. The friendship continued until the death of the lady, whom the artist survived only a few months. In 1818 a further and greater honour than any that had come his way hitherto was conferred upon Sir Thomas. He was sent to Aix-la-Chapelle to paint members of the Congress then sitting there, with instructions to proceed to Vienna and Rome. An allowance of one thousand a year for travelling expenses made the commission still more attractive, and the artist, free at last to travel and to work in the most stimulating surroundings Europe could provide, remained away from England for a year and a half. In his work he distinguished himself. His sitters included Emperor Francis of Austria, Louis XVIII., Charles X., Archduke Charles, Metternich, Techernicheff, Ouvaroff, Hardenberg, Nesselrode, Baron Gentz, Earl Bathurst, Lord Liverpool, the Marquis of Londonderry, the Duke of Cambridge, and Mr. Canning. In Rome the aged Pontiff Pius VII. gave him nine sittings, and he painted the portrait of the great Cardinal Gonsalvi, “the Pitt of Rome.” But it was not only to paint that he went to the Eternal City; he had much to learn, and some of the letters he wrote to London during his stay are remarkable for their sound judgment and insight. The supreme master of art for him was Michael Angelo, following him Raphael, Correggio, Titian, Sir Joshua, and perhaps J. M. W. Turner came in the order named. To the end Lawrence was faithful in his devotion to the art of the first President of the R.A. “I don’t see why British artists wish to travel abroad when we have Sir Joshua in England,” he said in his untravelled days. He was not heard to express this opinion again in the years when he had crossed “the narrow seas.” Eighteen months of foreign travel did much for him; he brought a wider mind and a bigger intelligence home with him; to say nothing of a collection of gifts
