Ptolemy. Almagest
[Bk. 4 Ch. 6 p. 191]

First the three ancient eclipses which are selected from those observed in Babylon. The first is recorded as occurring in the first year of Mardokempad, Thoth [month I] 29/30 in the Egyptian calendar [-720 Mar 19/20]. The eclipse began, it [the report] says, well over an hour after moonrise and was total. Now since the Sun was near the end of Pisces, and [therefore] the night was about 12 equinoctial hours long, the beginning of the eclipse occurred, clearly, 4 1/2 equinoctial hours before midnight.

Now we take as the standard meridian for all time deterĀ­minations the meridian through Alexandria, which is about 5/6 of an equinoctial hour in advance [i.e. to the west] of the meridian through Babylon So at Alexandria the middle of the eclipse in question was 3 1/3 equinoctial hours before midnight, at which time the true position of the sun, according to the [tables] calculated above, was approximately (?) 24 1/2Ā°.
