The clay coffins, shaped like a dish-cover, are among the most curious of the sepulchral remains of antiquity. On a platform of sun-dried brick is laid a mat exactly similar to those in common use among the Arabs of the country at the present day; and hereon lies the skeleton disposed as in the brick vaults, and surrounded by utensils and ornaments. Mat, skeleton, and utensils are then concealed by a huge cover in burnt clay, formed of a single piece, which is commonly seven feet long, two or three feet high, and two feet and a half broad at the bottom. It is rarely that modern potters produce articles of half the size.
