FUKIDID: MENTIONED IN HIM ECLIPSES PROBLEM SOLUTION
Fukidid the author of book about Pellopones war, writes about severask eclipses in his book. We quotate him by (1). p.499
"About eclipses in Fukidid's book is going in four places. In book 1 in general, in book 2 about total Sun in Athens, in book IV about part Sun (in seven years after the first) and in book VII about Moon one, in 18 years after the first, on 19-th year of war"
The first one isn't in our interest so we shall comprehensively quotate information about all of others.
The first three in our interest:
"In this summer time (in which athenians exiled the inhabitants from Egina to Firea, considered they as main war culprits), in new Moon - it seems then only it's possible, Sun was eclipted and in afternoon it became whole again taking shape of halfmoon and several stars had appeared".
The second one:
"The winter campaign went
to end and the seventh year of the war was coming to end, the history of
which is described by Fukidid. In the beginning of the next summer company
(i.e. the eigth year) the Sun eclipse was held and in first ten days of
the same month (i.e. March, when the campaign was began after winter breaks)
was the earthquake (Fukidid, IV,51-52)"
The last one, third:
"When (in summer campaign
of 19-th year of war) everything was prepared to sailing (from Sicilia)
and athenians was intended to sail Moon eclipse was held. hen there waas
a full Moon(Fukidid, VII-50-51)".
Hence we obtain the problem
in three eclipses:
- the first is Sun full
in Athens in afternoon in year N,
- the second is Sun in
nondetermined prat of year, most eventually in spring, in Greece in year
N+7,
- the thord is Moon in
year N+18.
We shall solute this problem according to Krasilnikov's canon.
For every whole Sun eclipse observed from Athens in year range -1000 till +1400 (with phase no less 0,8) we shall choose corresponding nonfull Sun and Moon.
All results of search we place in the table 1. This tableis composed so: in upper row of each block is writing Sun eclipse observed from Athens and helding in year N, the second row is part eclipse observed in year N+7, in third row there are Moon eclipses held in year N+18. The time of eclipses is Grinvich.

From abovementined pairs the first two are so ancient. In the third ehich is traditional, the Sun eclipse in Athens isn't full once more it was observed in 17-00 local time (non afternoon). So if as criterium of problem silution the principle of guaranteed observing all of eclipse the best solution there will be eclipses with phases being closely to guaranteed observing. So the last two solutions are passing the most of all. We shall write it in table 2.

In the last three the third eclipse was obviously winter one. So most passing solution is first among two threes.
May be about this eclipse is going in Plutarch.
