Since the sun’s declination in this eclipse was only eight 
seconds, it may safely be neglected in the calculation ; and it 
may then be found very easily by plane trigonometry that the 
sun rose centrally eclipsed in N. lat. 47 0 34', and W. long. 1 T 
33' ; that it was centrally eclipsed on the meridian in N. lat. 
31 0 6 ', and E. long. 59 0 33'; and set centrally eclipsed in N. 
lat. n° 13b and E. long. 122° 36'. The centre of the moon’s 
shadow crossed the parallel of N. lat. 42 0 in E. long. 34 0 43' ; 
and the parallel of N. lat. 36° in E. long. 30° : and conse- 
quently passed nearly in a straight line over the north-eastern 
part of Asia Minor, through Armenia and Persia, where the 
sun became centrally eclipsed on the meridian, as above-men- 
tioned. This eclipse, therefore, was central and total to part of 
Asia Minor, Armenia, and Media: and the path of the moon’s 
umbra lay in the very track where the two hostile armies 
probably met. For it passed over the very mouth of the 
Halys, just at the point where Croesus, the immediate successor 
of Alyattes, crossed that river in order to attack the Median 
empire. 
It would appear from the order of events belonging to the 
reign of Cyaxares, as related by Herodotus, that the battle of
