The grounds of the Chronology here followed, I will now set down as briefly as I can.
The Peloponnesian war began in spring An. 1 Olymp. 87, as Diodorus, Eusebius, and all other authors agree. It began two months before Pythodorus ceased to be Archon, Thucyd. l. 2. that is, in April, two months before the end of the Olympic year. Now the years of this war are most certainly determined by the 50 years distance of its first year from the transit of Xerxes inclusively, Thucyd. l. 2. or 48 years exclusively, Eratosth. apud Clem. Alex. by the 69 years distance of its end, or 27th year, from the beginning of Alexander's reign in Greece; by the acting of the Olympic games in its 4th and 12th years, Thucyd. l. 5; and by three eclipses of the sun, and one of the moon, mentioned by Thucydides and Xenophon. Now Thucydides, an unquestionable witness, tells us, that the news of the death of Artaxerxes Longimanus was brought to Ephesus, and from thence by some Athenians to Athens, in the 7th year of this Peloponnesian war, when the winter half year was running; and therefore he died An. 4 Olymp. 88, in the end of An. J.P. 4289, suppose a month or two before midwinter; for so long the news would be in coming. Now Artaxerxes Longimanus reigned 40 years, by the consent of Diodorus, Eusebius, Jerome, Sulpitius; or 41, according to Ptol. in can. Clem. Alexand. l. 1. Strom. Chron. Alexandr. Abulpharagius, Nicephorus, including therein the reign of his successors Xerxes and Sogdian, as Abulpharagius informs us. After Artaxerxes reigned his son Xerxes two months, and Sogdian seven months; but their reign is not reckoned apart in summing up the years of the Kings, but is included in the 40 or 41 years reign of Artaxerxes: omit these nine months, and the precise reign of Artaxerxes will be thirty nine years and three months. And therefore since his reign ended in the beginning of winter An. J.P. 4289, it began between midsummer and autumn, An. J.P. 4250.
The same thing I gather also thus. Cambyses began his reign in spring An. J.P. 4185, and reigned eight years, including the five months of Smerdes; and then Darius Hystaspis began in spring An. J.P. 4193, and reigned thirty six years, by the unanimous consent of all Chronologers. The reigns of these two Kings are determined by three eclipses of the moon observed at Babylon, and recorded by Ptolemy; so that it cannot be disputed. One was in the seventh year of Cambyses, An. J.P. 4191, Jul. 16, at 11 at night; another in the 20th year of Darius, An. J.P. 4212, Nov. 19, at 11h. 45' at night; a third in the 31st year of Darius, An. J.P. 4223, Apr. 25, at 11h. 30 at night. By these eclipses, and the Prophecies of Haggai and Zechary compared together, it is manifest that his years began after the 24th day of the 11th Jewish month, and before the 25th day of April, and by consequence about March. Xerxes therefore began in spring An. J.P. 4229: for Darius died in the fifth year after the battle at Marathon, as Herodotus, lib. 7, and Plutarch mention; and that battle was in October An. J.P. 4224, ten years before the battle at Salamis. Xerxes therefore began within less than a year after October An. J.P. 4228, suppose in the spring following: for he spent his first five years, and something more, in preparations for his expedition against the Greeks; and this expedition was in the time of the Olympic games, An. 1 Olymp. 75, Calliade Athenis Archonte, 28 years after the Regifuge, and Consulship of the first Consul Junius Brutus, Anno Urbis conditæ 273, Fabio & Furio Coss. The passage of Xerxes's army over the Hellespont began in the end of the fourth year of the 74th Olympiad, that is, in June An. J.P. 4234, and took up one month: and in autumn, three months after, on the full moon, the 16th day of the month Munychion, was the battle at Salamis, and a little after that an eclipse of the sun, which by the calculation fell on Octob. 2. His sixth year therefore began a little before June, suppose in spring An. J.P. 4234, and his first year consequently in spring An. J.P. 4229, as above. Now he reigned almost twenty one years, by the consent of all writers. Add the 7 months of Artabanus, and the sum will be 21 years and about four or five months, which end between midsummer and autumn An. J.P. 4250. At this time therefore began the reign of his successor Artaxerxes, as was to be proved.
The same thing is also confirmed by Julius Africanus, who informs us out of former writers, that the 20th year of this Artaxerxes was the 115th year from the beginning of the reign of Cyrus in Persia, and fell in with An. 4 Olymp. 83. It began therefore with the Olympic year, soon after the summer Solstice, An. J.P. 4269. Subduct nineteen years, and his first year will begin at the same time of the year An. J.P. 4250, as above.
His 7th year therefore began after midsummer An. J.P. 4256; and the Journey of Ezra to Jerusalem in the spring following fell on the beginning of An. J.P. 4257, as above.
