Wilson, ca 1881, vol 2, p 125: "This place, as the name implies, is famous for its potters´s clay. Its furnaces are dome-shaped and capable of burning enormous jars. The potter; mounted on a high seat, sets the wheel in motion with his foot and shapes the clay with his hand. The man beyond is adding handles to the jars."
