It will be observed that only two of these nine sets of 

 eclipses are in months conformable to my published table. 



I proceeded to consider which of these sets of eclipses could 

 all of tbem be visible at Nineveb. To facilitate calculation I 

 made use of Largeteau's Mondtafeln in von Gumpacb's Hülfs- 

 bucb der reebnenden Chronologie, which give the true time of 

 Opposition of the sun and moon with tolerable aecuraey. I 

 calculated by these tables the true time of Opposition at each 

 eclipse of each set, until I came to one which was evidently 

 invisible at Nineveh. The result is as follows. The time is 

 here Nineveh time from midnight, deduced from the Paris time 

 of Largeteau's tables by adding 2'' 51 m for difference of longitude.

It appeared from this calculation that in only three of the 

 nine sets of eclipses would tbey all be visible at Nineveh; and 

 in only one of these would the second eclipse take place about 

 the time of sunrise. On the morning of the 13 th of September 

 — 701, tbe sun would begin to be visible at Nineveh, allowing 

 for the effect of refraction, about 5 h 33 m ; nearly an hour after 

 the Opposition as given by Largeteau's tables. Tbe eclipse might 

 very well terminate at the time of sunrise; and this is, I con- 

 fidently believe, what the Assyrian tablet states in the sentence 

 which follows the date of the eclipse. "The moon emerged 

 from the shadow while the sun was rising."
