William Hogarth was a great and original genius, who wrote comedies pictorially, satirized vice, and depicted all phases of life more in detail than is possible with the pen. He was early apprenticed to a silversmith; but the natural bent of his genius was too apparent and promising not to be encouraged by the study of art. In the dramatic and satirical departments of design he has never been excelled. It has been objected that his pictures are vulgar; but when we remember the period in which they appeared, and also the fact that they undoubtedly convey useful lessons of morality, we shall find ample excuse if not commendation for the artist. In 1753 he published his "Analysis of Beauty," in which he maintains that a waving line is essential to beauty. Hogarth composed comedies just as much as did Molière. It was a singular characteristic of this able designer and artist that he could not successfully illustrate another's work; he is known utterly to have failed in the attempt, though never in the successful illustration of his own ideas. Hogarth was also a historian, inasmuch as every picture he produced represented the manners and customs of the period. The interior scenes give us the exact style of the furniture and minutest domestic surroundings; while out of doors we have all the various modes of conveyance in use, and a faithful picture of the street architecture. Hogarth died in 1764. James Spencer, who was a personal friend of Hogarth, began life as a London footman; but the genius of an artist was born in him, and it gradually forced its way to the front. At odd moments he practised drawing and even painting with oils, whenever and wherever he could seize upon a brief chance. It happened that a professional portrait-painter was engaged to make a portrait of the head of the family where Spencer had long acted as footman. When the likeness was finished, he heard his master express some just dissatisfaction at its want of resemblance to the original. Spencer very humbly asked permission of his master to copy the painting and see if he could not get a good likeness. After expressing some astonishment at the request, his master assented. In a much briefer period than the first artist occupied, and without a single sitting on the part of his employer, Spencer astonished the family by producing not only a remarkable likeness, but an entirely satisfactory painting. With such a start the footman became a professional portrait-painter, and accumulated the means ere long to set up a fine London establishment.
