It is now about two years since Sir H. Rawlinson published his discovery of the Assyrian Canon, that is to say, of a list of annual functionaries in the kingdom of Assyria, extending over a period of about two hundred and seventy years of the duration of that great empire. This is the most valuable contribution towards the recovery of ancient Asiatic chronology which has been made since the time when Selden deciphered and published the contents of the Parian Chronicle, in the reign of Charles the First; and there is every reason to believe that by means of this document, in conjunction with the well-established dates of the early portion of the Babylonian Canon, we shall be enabled, not only to fix with certainty the dates of the reigns of thirteen kings of Assyria, reaching as early as the year B.C. 907; but also, with much probability, to recover the exact date of the rise of the first Chaldean dynasty in Assyria; or, in other words, the commencement of the era of Ninus and Semiramis. Sufficient time has now elapsed for a full investigation of the contents and bearing of this valuable document, and three eminent Assyrian scholars, viz., Sir H. Rawlinson in England, Dr. Hincks in Ireland, and Monsieur Oppert in Paris, after careful and independent examination, have published their comments upon it. They are as yet undecided as to what was the exact nature of the functions of these annual officers, whether military, civil, or priestly.
