Ceramics. Art of pottery-making, and oldest of all the arts; for the rudest savage must soon have artificially applied the natural process of rain-softened and sun-burned clay. The potter's wheel appears on the Theban monuments, having probably traveled westward from China. In historical research the evidence afforded by ceramics is invaluable since it was the means by which antiquity honored its dead. By the pottery of the tombs we learn the life of forgotten nations, and trace the geographical limits of successive races and empires. The potter's art was highly honored: there was a potter to the King of Judah, Numa established a potter's college in Rome and the Chinese Emperors multiplied decrees for the production of impossible porcelains and richly rewarded new varieties. European royal patronage came much later. Majolica was introduced by the Dukes of Urbino, and we owe
