The year of Trojan fall.
1 Description in the historical record that can estimate the age of falling Troy
① The capture of Troy was in the reign of Menestheus the son of Peteus.
(Eusebius.Chron.185)
② In the reign of Demophon the son of Theseus, Diomedes (the son of Tydeus) was returning home from the capture of Troy. (Paus.1.28.9)
③ Troy was taken, in the first year of the reign of Demophon the son of Theseus at Athens, on the twelfth day of the month Thargelion.(Cleme.Str.1.21)
From the above description, the Trojan fall is presumed to be the year in which Demophon the son of Theseus crowned upon King Athenians.
2 The first year of the reign of Demophon
In twelfth year of the reign of the 29th king Aeschylus, the son of Agamestor, of Athens, the first Olympiad was held. [Eusebius.Chron.187] Because that year is BC 776, the first year of the reign of Aeschylus is presumed BC 788.
By Eusebius Chronicle, back to the reign of successive Athenians kings, the first year of the reign of the 12th king Demophon of Athens will be BC 1187.
3 The year of Trojan fall
From the above, Trojan fall is presumed to be May 20, 1187 BC.
