Certainly, however, we may gather that the Tang era was one of learning and literary progress in Corea, as in Japan—all countries in pupilage to China feeling the glow of literary splendor in which the Middle Kingdom was then basking. The young nobles were sent to obtain their education at the court and schools of Nanking, and the fair damsels of Shinra bloomed in the harem of the emperor. Imperial ambassadors frequently visited the court of this kingdom in the far east. Chinese costume and etiquette were, for a time, at least, made the rigorous rule at court. On one occasion, in 653 A.D., the envoy from Shinra to the mikado came arrayed in Chinese dress, and, neglecting the ceremonial forms of the Japanese court, attempted to observe those of China. The mikado was highly irritated at the supposed insult. The premier even advised that the Corean be put to death; but better counsels prevailed. During the eighth and ninth centuries this flourishing kingdom was well known to the Arab geographers, and it is evident that Mussulman travellers visited Shinra or resided in the cities of the peninsula for purposes of trade and commerce, as has been shown before. Kion-chiu, the capital of Shinra, was a brilliant centre of art and science, of architecture and of literary and religious light. Imposing temples, grand monasteries, lofty pagodas, halls of scholars, magnificent gateways and towers adorned the city. In campaniles, equipped with water-clocks and with ponderous bells and gongs, which, when struck, flooded the valleys and hill-tops with a rich resonance, the sciences of astronomy and horoscopy were cultivated. As from a fountain, rich streams of knowledge flowed from the capital of Shinra, both over the peninsula and to the court of Japan. Even after the decay of Shinra’s power in the political unity of the whole peninsula, the nation looked upon Kion-chiu as a sacred city. Her noble temples, halls, and towers stood in honor and repair, enshrining the treasures of India, Persia, and China, until the ruthless Japanese torch laid them in ashes in 1596. The generation of Corean people during the seventh century, when the Chinese hordes desolated large portions of the peninsula and crushed out Hiaksai and Korai, saw the borders of Shinra extending from the Everlasting White Mountains to the Island of Tsushima, and occupying the entire eastern half of the peninsula. From the beginning of the eighth until the tenth century, Shinra is the supreme state, and the political power of the Eastern Kingdom is represented by her alone. Her ambition tempted, or her Chinese master commanded, her into an invasion of the kingdom of Pu-hai beyond her northern border, 733 A.D. Her armies crossed the Tumen, but met with such spirited resistance that only half of them returned. Shinra’s desire of conquest in that direction was appeased, and for two centuries the land had rest from blood.
