Vandyck kept up a fine establishment, and lived luxuriously. He had a habit of asking his sitters to dinner; thus he could study their faces and retouch their portraits with the more natural expressions of their conversational hours, for it is rare that one is natural when posing before an artist who is painting one's portrait. But in the midst of his busy life as an artist and his gay life as a man of the world, Sir Anthony did not forget the needs of his brother painters. There was at that time no club or place where artists met socially to consult and aid each other in their profession. Vandyck founded the Club of St. Luke; it met at the Rose Tavern, and all painters of talent living in London joined it. One of the more personal acts of kindness which are related of him is that having seen by chance a picture which was painted by William Dobson, Vandyck sought him out, found him in a poor garret, instructed him with great care, introduced him to the king, and, in short, by his kind offices so prepared the way that Dobson was made sergeant-painter to the king after Vandyck's death, and won the title of "the English Tintoretto." The portraits which Vandyck executed in England are numbered by hundreds and are magnificent pictures. Those of the royal family are very numerous and important, and there is scarcely a man or woman belonging to this period whose name has come down to us in history or literature, whose portrait he did not paint. He also made thirteen portraits of himself which are still preserved. He was very skilful in painting horses and dogs, and frequently introduced these animals into his portrait groups. There is a large collection of the pictures of Vandyck at Windsor Castle; there are many also in the private galleries of Great Britain and other countries, besides a goodly number in the public galleries of Europe. He executed at least thirty-six portraits of Charles I., as many as twenty-five of Queen Henrietta Maria, and he also painted several groups of the children of the royal pair. Prince Rupert of the Rhine and Thomas Wentworth, Earl of Strafford, were also frequently portrayed by him, and one of his most important large works was a family picture of the Earl of Pembroke and his household. It is called the Wilton Family, as it is in a salon at Wilton House; it contains eleven figures, and has been called "the first and most magnificent historic portraiture in the world." Again, it is said to be stiff, wanting in harmony, bad in color, and so on, but after all it still remains a splendid monument to the skill and genius of Vandyck. The picture is twenty feet long by twelve feet high. Vandyck painted no portraits of the Puritans nor popular leaders of his day; neither did he of the literary men who flourished at that time, with the exception of the court poets, Sir John Suckling and Thomas Carew.
