Whose reckoning: this year is the chronographers' own construction (Hippias of Elis' victor list, taken over by Eratosthenes, Apollodorus, Africanus and Eusebius). Everything earlier in this band is dated by counting back from it.纪年归属：此年为编年家自身的构造（厄利斯的希庇亚斯胜者名录，后为埃拉托色尼、阿波罗多洛斯、阿非利加努斯、优西比乌沿用）。本时段更早的一切年代，皆由此上推。
