SEYFFARTH — ON THE THEORY OF THE MOON's MOTIONS. 469 



Accordingly, the following epochs of Grecian history are incon- 

 tiovertibly fixed in advance : 



I- — 777» ^^^ first year of Archon >^shylus. Euseb. Chron. ii. 318. 



2. — 477, battle near Thermopylae Her. vii. 206; Arch. Calliades. Par. 



Marb. Ep. 52; Her. viii. 51. 



3. — 425, the 4th year of Peloponn. war, Arch. Diotimus. Thuc. iii. 8.

philus. 

 10. — 321, Arch. Hegesias; Alexander the Great dies in the following 

 year. Arr. vii. 28, 1. 



All these epochs refer to the years in which the Olympian 

 games were actually held, and by means of thena it will be an 

 easy matter to determine the true dates of all the eclipses men- 

 tioned in the history of the Greeks. 



The following Chronological Table summarily shows the dif- 

 ference between Petavius's Greek history and that of the author, 

 and, at the same time, it includes the true dates of all Greek 

 eclipses. We add the epochs of the Persian kings, fixed by clas- 

 sic authorities. In the next place, the Olympian games confirm 

 the results (p. 409). that the Peloponnesian war lasted, from the 

 first naval expedition of the Athenians to the destruction of the 

 Piraeus, 28 full years, as Thucydides and Xenophon testify, and 

 not, as Petavius '■'■ post inge7item laborem'' made out, 37 years only; 

 that, moreover, the history of the 21st year of the Peloponnesian 

 war and the first chapters of Xenophon's Hellenica have been 

 lost. For, the Olympian games being held in the 4th and 12th 

 years of the Peloponnesian war (Thuc. iii. 8 ; v. 49), i.e. — 425 

 and —409, do not agree with the Olympian games celebrated dur- 

 ing the 23d and 27th years of the same war (Xen. Hell. ii. 3, i, 

 and i. 2, i), i.e., according to Petavius, in — 406 and — 402, 

 because the games would have been repeated after an interval of 

 3 years. Besides, the years — 406 and — 402 disagree with the 

 epochs of all Olympian games mentioned in Roman history 

 (p. 451). The aforesaid loss of one year of the Peloponnesian
