By meini of the data in the preceding Table, we 

 may canly convert the years of any one rra in those of 

 another ; and as the method of doing this is frequently 

 of the greatest use, we (hall illustrate it by a few ex- 

 ample*. 



;/<!. Cyrui took Babylon in the year of the 

 world 3>6 ; to what Olympiad does this year corre- 

 spond? 



Make a = the given year, e =r the corresponding 

 epoch in the Table, diminished by 1. Then the Olym- 

 piad will be 1, the remainder being the year of 



the Olympiad. Thus, in the preceding example, the 



S46fi 3227 



formula will become 1 = 59 with a re- 

 mainder of 3, which shews that the event happened in 

 the 3d year of the 59th Olympiad. 



Example 2. Socrates died in the 1st year of the 

 95th Olympiad ; in what year of the world did this 

 event happen ? 



The death of Socrates, which happened in the 1st year 

 of the 95th Olympiad, happened also in the 



The Peace of Westphalia, which happened in the year 

 of the world 5652, happened aUo in the

Tabular Chronology. 



TABU L.\n Chronology, is that branch of the science in 

 which all the leading events recorded in history are ar- 

 ranged in a chronological order, or in the order of time 

 in which they happened. Along with the great political 

 events which accompany the rise and fall of empires, 

 these tables ought to include the leading facts in the 

 arts and sciences the most striking natural phenomena, 

 such as total and central eclipses, the appearance of co- 

 mets, unusual conjunctions of the planets, the fall of me- 

 teoric stones, meteors, hurricanes, inundations, volcanic 



The year 1792 of the Christian Mrt. 

 The year 5796 of the Creation of the World. 

 The year 1 of the titSd Olympiad. 

 The year 2545 of the foundation of Rome. 

 The year 1206 of the Hegira. 

 . The year 6506 of the Julian Period. 



Let <7 be the number of the Olympiad, b the year of Ue of the 

 the Olympiad, and c the corresponding epoch diminished preceding 

 by 1. Then the year of the world will be a I X 4 + Ublc> 

 b 4. e, or 4 a 4 + b + r, which gives for answer 3(0 1 . 



['.xamplc 3. To what year of the Christian xra does 

 the 4th year of the ~\:\\ Olympiad correspond ? 



The letters denoting the same things as before, we 

 have a 1 X 4 + * c, or 4 u -- \ + l> c, \\ 

 gives the year of Christ required, 481. 



The formula in Example '2, and 3, is general for the 

 translation of Olympiads into the years of other seras, or 

 rice versa, with this difference only, that when the other 

 zra is after the Olympiads, the quantity e is negative, 

 and has the sign ; whereas when the other zra is 

 before the Olympiads, the quantity c has the sign + 



It would be an endless task to multiply examples for 

 all the other seras ; but those who wish to draw up 

 rules for themselves, will derive assistance from the fol- 

 lowing Table, which comprehends also some of the mi- 

 nor xras mentioned in page 413.

eruptions, &c. and an account of the philosophers, 

 statesmen, and warriors, who have acted a leading part 

 in the revolutions of kingdoms and of science. By this 

 means we obtain, at one glance, a general view of the 

 various steps in the progress of society, and the eye of 

 the reader becomes a useful auxiliary to his memory and 

 judgment. 



In drawing up the following Table, we have obtained 

 great assistance from the Chronological Tables of Blair, 

 Playfair, and Chantreaux ; but we have presented the 

 various events in the most abridged form, and have thus 

 made room for many new and curious facts and pheno- 

 mena which have never before been included in Chrono- 

 logical Tables.
