In this Table the extent of the _Ethnocratic age_ is 587 years according to the Canon of Ptolemy;[125] this is 2 years more than we assigned at p. 80, owing to the reign of Cyrus being estimated at 9 years instead of 7, which brings the _Sixth age_ up to the vulgar era of the Birth of our Saviour. The Canon assigns 43 years respectively to the reigns of Nebuchadnezzar and Augustus Cæsar; hence the former reigned 25 years after the taking of Jerusalem,[126] and the latter 28 before the Christian era;[127] thus the extreme intervals of the first column of the table were obtained. The intervals of Josephus were determined from the following passages:—Book XI. 1, 1, “In the first year of the reign of Cyrus, and this was the 70th from the day that it befell our people to remove from home to Babylon;”—Book XX. 10, 1, “After the period of the 70 years’ captivity, &c. Joshua the Son of Josedek, took the office of High Priest; and his posterity, in all 15, held the democratic form of government for 414 years, till the reign of Antiochus Eupator;”—Book XIV. 16, 4, “Thus ceased the government of the Asamonean [race] after 126 years;”—Book XVII. 6, 3, “for 125 years during which they [the Asamoneans] reigned;”—and, Book XVII. 8, 1, “Having reigned, after he [Herod] caused the death of Antigonus, 34 years, and after he was appointed by the Romans, 37 years.”[128] Now, taking the period of the Asamonean dynasty at 125 years, and the years of the reign of Herod before Christ was born, at 33, we have, from the preceding extracts, the intervals in the Table, and the extent of the whole period 642 years, according to Josephus. This result receives a striking confirmation from the summation of the periods contained in the Titles of the different Books of the Antiquities which relate the History from the 1st year of Cyrus to the death of Herod.
