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 conditae_ 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.
