The rings and top-pieces of the drainage-shafts also exhibit much skill and knowledge of principles.
Hitherto, however, the reader has not been brought into contact with any specimens of Chaldaean fictile art which can be regarded as exhibiting elegance of form, or, indeed, any sense of beauty as distinguished from utility.

Such specimens are, in fact, somewhat scarce, but they are not wholly wanting.

Among the vases and drinking vessels with which the Chaldaean tombs abound, while the majority are characterized by a certain rudeness both of shape and material, we occasionally meet with specimens of a higher character, which would not shrink from a comparison with the ordinary productions of Greek fictile art.

A number of these are represented in the second figure [PLATE XIII., Fig 2], which exhibits several forms not hitherto published-some taken from drawings by Mr.
Churchill, the artist who accompanied Mr.Loftus on his first journey; others drawn for the present work from vases now in the British Museum.
[Illustration: PLATE 13] It is evident that, while the vases of the first group are roughly moulded by the hand, the vases and lamps of the second have been carefully shaped by the aid of the potter's wheel.

These last are formed of a far finer clay than the early specimens, and have sometimes a slight glaze upon them, which adds much to their beauty.
In a few instances the works of the Chaldaeans in this material belong to mimetic art, of which they are rude but interesting specimens.
