Most significant for the position occupied by the priests, is the fact that the latter are invariably the scribes who draw up the documents.
The archaeological material furnished by the excavations consists of the temples of the gods, their interior arrangement, and provisions for the various religious functions; secondly, the statues of the gods, demigods, and the demons, the altars and the vessels; and thirdly, the religious scenes,--the worship of some deity, the carrying of the gods in procession, the pouring of libations, the performance of rites, or the representation of some religious symbols sculptured on the palace wall or on the foundation stone of a sacred building, or cut out on the seal cylinders, used as signatures[10] and talismans.
Large as the material is, it is far from being exhausted, and, indeed, far from sufficient for illustrating all the details of the religious life.

This will not appear surprising, if it be remembered that of the more than one hundred mounds that have been identified in the region of the Tigris and Euphrates as containing remains of buried cities, only a small proportion have been explored, and of these scarcely more than a half dozen with an approach to completeness.

The soil of Mesopotamia unquestionably holds still greater treasures than those which it has already yielded.

The links uniting the most ancient period--at present, _c._ 4000 B.C .-- to the final destruction of the Babylonian empire by Cyrus, in the middle of the sixth century B.C., are far from being complete.

For entire centuries we are wholly in the dark, and for others only a few skeleton facts are known; and until these gaps shall have been filled, our knowledge of the religion of the Babylonians and Assyrians must necessarily remain incomplete.
