" thirty-year periods," of the Rosetta Stone) ; for these correspond to 

 the already-given larger Divisions of Time, 



30 years . . . . = a panegyry. 

 22 panegyries = 660 years = a phoenix. 

 2} phoenixes = 1540 years = a Great Year. 



4. Another line in the Turin Papyrus, is given by Bunsen as fol- 

 lows, 



"13,420 years." (=1540 x 9—440 = 9 Great Years— f phoenix.) 



5. According to Julius Africanus, The first book of Manetho's His- 

 tory of Egypt contained the events of 



"2308 years 70 days." (2310 = 1540 + 770=1* Great Years). 



6. Claudius Ptolemy, according to his own statement, "made his 

 Observation of the Vernal Equinox in the third year of Antoninus" 

 (A. D. 139, Clinton) ; and he further names "the seventh of the Egyp- 

 tian month Pachon," as the equinoctial day. On comparing the fixed 

 and movable calendars, the twentieth of July being the admitted 

 starting place, 



March 10 + April 30 + May 31 + June 30 + July 19 =120 



Pachon 23 + Paoni 30 + Abib 30 + Misra 30 + Epagomena 5=118 



we find a deficiency of two days: but morning being the time of adjust- 

 ment, and the equinox in question taking place " one hour after noon," 

 we may assume a deficiency of 21 days; and that the Great Year ended 

 (21 x 4=) 11 years previously, or in A. D. 128 : 



From this date, counting backwards (1540 — 128 — 1, the latter 

 deduction being required on reversing the order of reckoning), we 

 obtain, 



for the commencement of this Great Year, B. C. 1413. 



" Apion placed the Exodus in the 1st yr. 7th Olympiad" (B. C. 751, Clinton), 



662 ( — 2=a phoenix). 



Compare with this, the date of the alleged "burning of Bocchoris 

 by Sabaco ;" and Lysimachus' placing " the Exodus under Bocchoris "
