At about the period of Ching-hwa, Europeans were making efforts to reach the East by sea, and in 1498 Vasco de Gama sailed round the Cape of Good Hope, and thus made an opening, by which eventually trade was carried on by sea to China. The Portuguese were the first to settle in China in 1516. From their factory or settlement in Macco, or Macao, at the entrance to the Canton river, the first sea-borne pieces of Oriental porcelain were sent to Europe by way of the Cape. The conclusion, therefore, must be, in view of these dates, that the earliest pieces found in England and on the Continent were carried overland, by camels, thousands of miles over mountains and through deserts, till at last they reached their European owners. The earliest porcelain found in England--that is, a Celadon bowl presented to New College, Oxford, by Archbishop Warham, and the bowls of Oriental china given in 1506 by Philip of Austria to Sir Thomas Trenchard--came by land. The Portuguese vessels were not content to sail only to China and to exchange its products for those of Europe, for in 1542 they appeared in Japan. Fernam Mendez Pinto in his "Travels," published in 1545, states that he and his companions were cordially received by the Prince of Japan. Evidently, then, at the time when Queen Elizabeth was reigning in England the Portuguese were pushing their trade in the East as the Spaniards were in the West, and, as we have seen, the Portuguese, amongst other commodities, sent Oriental porcelain home, and brought European products back. They brought the Jesuits too. Christian teachers had been at work in China for long years before the Jesuits came, but the activity and knowledge of these gave them great influence amongst the reigning class practically from the close of the sixteenth to the beginning of the eighteenth century. It is said that they had much to do with the evolution of the beautiful enamel colours of the next dynasty, the "Tsing," though the evidence of this is of the slightest. On the contrary, the development appears to have had purely a native origin; an unusual step, it is true, to be taken by a nation which seemed all along the line to be reproducing earlier forms and earlier decoration. From the period when the vases of the Yung-lo period were in demand, painted as they were with lions rolling a ball, with birds or with dark blue or red flowers, we find progress being continually made.
