The literature of the Chaldeans is very varied in its forms. The hymns to the gods form an important department, and were doubtless employed in public worship. They are by no means lacking in sublimity of expression, and while quite unmetrical they are proportioned and emphasized, like Hebrew poetry, by means of parallelism. In other respects they resemble the productions of Jewish psalmists, and yet they date as far back as the third millennium before Christ. They seem to have been transcribed in the shape in which we at present have them in the reign of Assurbanipal, who was a great patron of letters, and in whose reign libraries were formed in the principal cities. The Assyrian renaissance of the seventeenth century B.C. witnessed great activity among scribes and book collectors: modern scholars are deeply indebted to this golden age of letters in Babylonia for many precious and imperishable monuments. It is, however, only within recent years that these works of hoar antiquity have passed from the secluded cell of the specialist and have come within reach of the general reader, or even of the student of literature. For many centuries the cuneiform writing was literally a dead letter to the learned world. The clue to the understanding of this alphabet was originally discovered in 1850 by Colonel Rawlinson, and described by him in a paper read before the Royal Society. Hence the knowledge of Assyrian literature is, so far as Europe is concerned, scarcely more than half a century old.
