Along with learning and religion, various arts of civilized life were profusely supplied from Korea to vivify the general progress of the nation. Among the most important was the production and manufacture of silk, which was largely studied by the people and encouraged by the Emperor Yūryaku. Many Chinese artisans of the fallen dynasties migrated through Korea to Japan, where they were naturalized and transmitted their knowledge of the western arts and sciences. In architecture, also, with the coming of Buddhism a need arose for lofty and large edifices, the erection of which must have greatly changed the appearance of the capital. The art of pottery made a great advance, as did the blacksmith's craft of forging swords and other articles of iron. Nor were medicine and the calendar neglected, while the new art of carving and decorating as well as drawing the image of Buddha, gave a powerful impetus to painting and sculpture. The collective influence of all these and other new changes upon the life of the people, nearer the center of the government at least, must have been very great. With the development of the art of weaving, apparel was improved by the addition of silk garments; as agriculture progressed, rice and other cereals furnished agreeable aliment; the influence of Buddhism gradually produced a distaste for animal food. The introduction of the science of architecture soon effected a marked change in the dimensions and decoration of dwelling-houses. Transmission of intelligence was facilitated by the imported art of writing, the moral, intellectual, and political thinking of the ruling classes began to take a more or less definite shape from the coming of the Chinese classics, while Buddhism spread over the nation a charm which was at once captivating and ennobling. A new era of history had begun.
