The opposition in longitude occurred therefore at Ri’ 6” 28* Greenwich Mean 
Solar Time, or about 15^ 59“ Sardes Mean Solar Time; and the Moon’s South Lati- 
tude was 11' 51"'l ; which would be reduced to about 10' 35" by the corrections at 
which I arrived in Section IV. It was therefore a total eclipse, nearly central (the 
moon’s limb being at least 16' within the inner boundary of the penumbra), and it is 
probable that the moon disappeared completely, and was lost for nearly two hours. 
54. I think it extremely probable that this really was the eclipse to which the 
account of Herodotus refers. But for its adoption it is necessary to bring down the 
date of the battle of Salamis one year later than in the chronology generally received.
