238 Mr. Baily on the Solar Eclipse 
SlCULUS, lib. 20, (pxvvjvxi vw era, $ect>(>ovy,ei/uv tuv ctcrTE(>av 
Truvrux*, “ it seemed exactly like night, the stars every zvhere 
“ appearing.” This eclipse was therefore evidently total in 
the place where it was seen by the fleet of Agathocles. It 
happened on August 15th, 310 B. C. The ecliptic conjunc- 
tion took place at S h 10' 23" in the morning, mean time at 
Greenwich, or 8 h g' 6 " apparent time : and the elements were 
as follow :

From these elements I have found, by a trigonometrical 
calculation, that the sun rose centrally eclipsed to the inhabi- 
tants of the western coast of Africa, in N. lat. 24 0 37' and W. 
long. 14 0 g'. The centre of the moon’s shadow then, crossing 
the desert, proceeded towards the Mediterranean, near to, but 
rather to the southward of, Tripoli ; and crossed the parallel 
of N lat. 33 0 in E. long. 20° 44'. But in no part of its course 
did it advance more northerly than N. lat. 33 0 55' 36", which 
I find by a trigonometrical calculation to be its maximum of 
latitude, and the parallel of which it reached in E. long. 33° 
21/ 8". It then turned to the south; and the sun became 
centrally eclipsed on the meridian in N. lat. 30^° and E. long. 
59 ° 45'-
