SEYFFAKTH— ON THE THEORY OF THE MOON*S MOTIONS. 481 



2J^. Justinus (xxii. 6) and Diodor (xx. 5, p. 409 S.) relate that 

 tluring &e[to^ of 01. 117, 3, consequently in the summer of — 306, 

 the 7th year of King Agathocles of Sicily, whilst Hieromnemon 

 was archon in Athens, a total eclipse of the sun occurred between 

 Syracuse and Carthage. This eclipse happening one day after 

 the fleet left Syracuse, the locality and the time of this really total 

 eclipse of the sun are sufficiently fixed (r^ ^' baxziKua zrfMxa'jrr^v

 &zw(>o'Jii£vco'u rwv dazsfno)^ 7:a\^zayo\)). Petavius recurred, of 

 course, to the eclipse in — 309, Aug. 14th, 2oh. 15m., ii 4° W., 

 curve 42°, 35°, —4°, obscuration 10 inches ; but, alas ! this eclipse 

 occurred in ytifiion and not in &£[>o^^ and the archons of this 

 time ruled two, even three, years later than Petavius believed. 

 About that time, viz. in &£(jo^^ only one total eclipse of the sun 

 was possible near Syracuse, i.e. that in —306, June 13, 22h, 45m., 

 ft 0° 43' E., curve 0°, 21°, _3°. According to our Table, p. 429, 

 the ft lay 4° W. of the sun, and hence the obscuration of the sun 

 was total near Syracuse. The calendrical inscription (p. 412) 

 referring to Archon Nicodorus mathematically demonstrates that 

 the archons of this time ruled two, even three, yeai's later than 

 Petavius made out. Compare No. 19, p. 47<^, and the eclipses, 

 discussed further on, referring to - 197 and —196 (Babylonian 

 eclipses Nos. 11, 12, 13). 



2d. Diogenes Laert. (iv. 9, 64) reports that, according to Apol- 

 lodor (Ol. 162, 4), the death of Carneades was followed by an 

 eclipse of the moon (sz/^^rc azlrji/r^^) in Athens. On occasion 

 of the ecliptic full moon in — 126, Oct. 14, I3h. 30m., ft 9° W., 

 which the Olympiads point to, 6 inches were obscured. This 

 eclipse, however, being too small, and Apollonius living in later 

 times, we may presume the Olympiads to have been counted from 

 — 775, and in this case Apollonius and Diogenes Laertius would 

 have had in view the two-years earlier eclipse in 1 28, Nov. 5th, 

 1311. 30m., ft 7*^ E., which was, according to our Table (p. 429,) 

 a total one, because the longitude of the ft was 4'^' 12' shorter. 



26. Plutarch (De fac. i. o. 1. chap. 13, vol. ix., p. 680 R. ; see 



the passage p. 461),. being born a.d. 45 (Clinton F. R. p. 85) in 



Chaeronea, Boeotia, became when nearly 20 years old a pupil of 



Ammonius in Athens (Plutarch De £f, p. 385), and returned,
