Thus the _Greek_ Chronologers, who follow _Timæus_ and _Eratosthenes_, have made the Kings of their several Cities, who lived before the times of the _Persian_ Empire, to Reign about 35 or 40 years a-piece, one with another; which is a length so much beyond the course of nature, as is not to be credited. For by the ordinary course of nature Kings Reign, one with another, about eighteen or twenty years a-piece: and if in some instances they Reign, one with another, five or six years longer, in others they Reign as much shorter: eighteen or twenty years is a medium. So the eighteen Kings of _Judah_ who succeeded _Solomon_, Reigned 390 years, which is one with another 22 years a-piece. The fifteen Kings of _Israel_ after _Solomon_, Reigned 259 years, which is 17¼ years a-piece. The eighteen Kings of _Babylon_, _Nabonassar_ &c. Reigned 209 years, which is 11⅔ years a-piece. The ten Kings of _Persia_; _Cyrus_, _Cambyses_, &c. Reigned 208 years, which is almost 21 years a piece. The sixteen Successors of _Alexander_ the great, and of his brother and son in _Syria_; _Seleucus_, _Antiochus Soter_, &c. Reigned 244 years, after the breaking of that Monarchy into various Kingdoms, which is 15¼ years a-piece. The eleven Kings of _Egypt_; _Ptolomæus Lagi_, &c. Reigned 277 years, counted from the same Period, which is 25 years a-piece. The eight in _Macedonia_; _Cassander_, &c. Reigned 138 years, which is 17¼ years a-piece. The thirty Kings of _England_; _William_ the Conqueror, _William Rufus_, &c. Reigned 648 years, which is 21½ years a-piece. The first twenty four Kings of _France_; _Pharamundus_, &c. Reigned 458 years, which is 19 years a-piece: the next twenty four Kings of _France_; _Ludovicus Balbus_, &c. 451 years, which is 18¾ years a-piece: the next fifteen, _Philip Valesius_, &c. 315 years, which is 21 years a-piece: and all the sixty three Kings of _France_, 1224 years, which is 19½ years a-piece. Generations from father to son, may be reckoned one with another at about 33 or 34 years a-piece, or about three Generations to an hundred years: but if the reckoning proceed by the eldest sons, they are shorter, so that three of them may be reckoned at about 75 or 80 years: and the Reigns of Kings are still shorter, because Kings are succeeded not only by their eldest sons, but sometimes by their brothers, and sometimes they are slain or deposed; and succeeded by others of an equal or greater age, especially in elective or turbulent Kingdoms. In the later Ages, since Chronology hath been exact, there is scarce an instance to be found of ten Kings Reigning any where in continual Succession above 260 years: but _Timæus_ and his followers, and I think also some of his Predecessors, after the example of the _Egyptians_, have taken the Reigns of Kings for Generations, and reckoned three Generations to an hundred, and sometimes to an hundred and twenty years; and founded the Technical Chronology of the _Greeks_ upon this way of reckoning.
