And the Cycles of that year.]

431. The _Dionysian_ or vulgar Æra of _Christ_’s birth was about the end

of the year of the _Julian_ Period 4713; and consequently the first year

of his age, according to that account, was the 4714th year of the said

Period. Therefore, if to the current year of _Christ_ we add 4713, the

Sum will be the year of the _Julian_ Period. So the year 1757 will be

found to be the 6470th year of that Period. Or, to find the year of the

_Julian_ Period answering to any given year before the first year of

CHRIST, subtract the number of that given year from 4714, and the

remainder will be the year of the _Julian_ Period. Thus, the year 585

before the first year of CHRIST (which was the 584th before his birth)

was the 4129th year of the said Period. Lastly, to find the Cycles of

the Sun, Moon, and Indiction for any given year of this Period, divide

the given year by 28, 19, and 15; the three remainders will be the

Cycles sought, and the Quotients the numbers of Cycles run since the

beginning of the Period. So in the above 4714th year of the _Julian_

Period the Cycle of the Sun was 10, the Cycle of the Moon 2, and the

Cycle of Indiction 4; the Solar Cycle having run through 168 courses,

the Lunar 248, and the Indiction 314.

[Sidenote: The true Æra of CHRIST’s birth.]

432. The vulgar Æra of CHRIST’s birth was never settled till the year

527; when _Dionysius Exiguus_, a _Roman_ Abbot, fixed it to the end of

the 4713th year of the _Julian_ Period; which was certainly four years

too late. For, our SAVIOUR was undoubtedly born before the Death of

_Herod_ the Great, who sought to kill him as soon as he heard of his

birth. And, according to the testimony of _Josephus_ (B. xvii. c. 8.)

there was an eclipse of the Moon in the time of _Herod_’s last illness:

which very eclipse our Astronomical Tables shew to have been in the year

of the _Julian_ Period 4710, _March_ 13th, 3 hours 21 minutes after

mid-night, at _Jerusalem_. Now, as our SAVIOUR must have been born some

months before _Herod_’s death, since in the interval he was carried into

_Ægypt_; the latest time in which we can possibly fix the true _Æra_ of

his birth is about the end of the 4709th year of the _Julian_ Period.

And this is four years before the vulgar _Æra_ thereof.

[Sidenote: The time of his crucifixion.]

In the former edition of this book, I endeavoured to ascertain the time

of CHRIST’s death; by shewing in what year, about the reputed time of

the Passion, there was a Passover Full Moon on a _Friday_: on which day

of the week, and at the time of the Passover, it is evident from _Mark_

xv. 42. that our SAVIOUR was crucified. And in computing the times of

all the Passover Full Moons from the 20th to the 40th year of CHRIST,

after the _Jewish_ manner, which was to add 14 days to the time when the

New Moon next before the Passover was first visible at _Jerusalem_, in

order to have their day of the Passover Full Moon, I found that the only

Passover Full Moon which fell on a _Friday_, in all that time, was in

the year of the _Julian_ Period 4746, on the third day of _April_: which

year was the 33d year of CHRIST’s age, reckoning from the vulgar Æra of

his birth, but the 37th counting from the true _Æra_ thereof: and was

also the last year of the 402d Olympiad[88], in which very year

_Phlegon_ an Heathen writer tells us, _there was the most extraordinary

Eclipse of the Sun that ever was known_, and that _it was night at the

sixth hour of the day_. Which agrees exactly with the time that the

darkness at the crucifixion began, according to the three Evangelists

who mention it[89]: and therefore must have been the very same darkness,

but mistaken by _Phlegon_ for a natural Eclipse of the Sun; which was

impossible on two accounts, 1. because it was at the time of Full Moon;

and 2. because whoever takes the pains to calculate, will find that

there could be no regular and total Eclipse of the Sun that year in any

part of _Judea_, nor any where between _Jerusalem_ and _Egypt_: so that

this darkness must have been quite out of the common course of nature.

From the co-incidence of these characters, I made no doubt of having

ascertained the true year and day of our SAVIOUR’s death. But having

very lately read what some eminent authors have wrote on the same

subject, of which I was really ignorant before; and heard the opinions

of other candid and ingenious enquirers after truth (which every honest

man will follow wherever it leads him) and who think they have strong

reasons for believing that the time of CHRIST’s death was not in the

year of the _Julian_ Period 4746, but in the year 4743; I find

difficulties on both sides, not easily got over: and shall therefore

state the case both ways as fairly as I can; leaving the reader to take

which side of the Question he pleases.

Both Dr. _Prideaux_ and Sir _Isaac Newton_ are of opinion that

_Daniel_’s seventy weeks, consisting of 490 years (_Dan._ chap. ix. v.

23-26) began with the time when Ezra received his commission from

_Artaxerxes_ to go to _Jerusalem_, which was in the seventh year of that

King’s reign (_Ezra_ ch. vii. v. 11-26) and ended with the death of

CHRIST. For, by joining the accomplishment of that prophecy with the

expiation of Sin, those weeks cannot well be supposed to end at any

other time. And both these authors agree that this was _Artaxerxes

Longimanus_, not _Artaxerxes Mnemon_. The Doctor thinks that the last of

those annual weeks was equally divided between _John_’s ministry and

CHRIST’s. And, as to the half week, mentioned by _Daniel_ chap. ix. v.

27. Sir _Isaac_ thinks it made no part of the above seventy; but only

meant the three years and an half in which the _Romans_ made war upon

the _Jews_ from spring in _A.D._ 67 to autumn in _A.D._ 70, when a final

Period was put to their sacrifices and oblations by destroying their

city and sanctuary, on which they were utterly dispersed. Now, both by

the undoubted Canon of _Ptolemy_, and the famous Æra of _Nabonassar_,

which is so well verified by Eclipses that it cannot deceive us, the

beginning of these seventy weeks, or the seventh year of the reign of

_Artaxerxes Longimanus_, is pinned down to the year of the _Julian_

Period 4256: from which count 490 years to the death of CHRIST, and the

same will fall in the above year of the _Julian_ Period 4746: which

would seem to ascertain the true year beyond dispute.

But as _Josephus_’s Eclipse of the Moon in a great measure fixes our

SAVIOUR’s birth to the end of the 4713th year of the _Julian_ Period,

and a _Friday_ Passover Full Moon fixes the time of his death to the

third of _April_ in the 4746th year of that Period, the same as above by

_Daniel_’s weeks, this supposes our SAVIOUR to have been crucified in

the 37th year of his age. And as St. _Luke_ chap. iii. ver. 23. fixes

the time of CHRIST’s baptism to the beginning of his 30th year, it would

hence seem that his publick ministry, to which his baptism was the

initiation, lasted seven years. But, as it would be very difficult to

find account in all the Evangelists of more than four Passovers which he

kept at _Jerusalem_ during the time of his ministry, others think that

he suffered in the vulgar 30th year of his age, which was really the

33d; namely in the year of the _Julian_ Period 4743. And this opinion is

farther strengthened by considering that our SAVIOUR eat his last

Paschal Supper on a _Thursday_ evening, the day immediately before his

crucifixion: and that as he subjected himself to the law, he would not

break the law by keeping the Passover on the day before the law

prescribed; neither would the Priests have suffered the Lamb to be

killed for him before the fourteenth day of _Nisan_ when it was killed

for all the people, _Exod._ xii. _ver._ 6. And hence they infer that he

kept this Passover at the same time with the rest of the _Jews_, in the

vulgar 30th year of his age: at which time it is evident by calculation

that there was a Passover Full Moon on _Thursday April_ the 6th. But

this is pressed with two difficulties. 1. It drops the last half of

_Daniel_’s seventieth week, as of no moment in the prophecy; and 2. it

sets aside the testimony of _Phlegon_, as if he had mistaken almost a

whole _Olympiad_.

Others again endeavour to reconcile the whole difference, by supposing,

that as CHRIST expressed himself only in round numbers concerning the

time he was to lie in the grave, _Matt._ xii. 40. so might St. _Luke_

possibly have done with regard to the year of his baptism: which would

really seem to be the case when we consider, that the _Jews_ told our

SAVIOUR, sometime before his death, _Thou art not yet fifty years old_,

John vii. 57. which indeed was more likely to be said to a person near

forty than to one but just turned of thirty. And as to his eating the

above Passover on _Thursday_, which must have been on the _Jewish_ Full

Moon day, they think it may be easily accommodated to the 37th year of

his age; since, as the _Jews_ always began their day in the evening,

their _Friday_ of course began on the evening of our _Thursday_. And it

is evident, as above-mentioned, that the only _Jewish Friday_ Full Moon,

at the time of their Passover, was in the vulgar 33d, but the real 37th

year of CHRIST’s age; which was the 4746th year of the _Julian_ Period,

and the last year of the 202d _Olympiad_.

[Sidenote: Æras or Epochas.]

433. As there are certain fixed points in the Heavens from which

Astronomers begin their computations, so there are certain points of

time from which historians begin to reckon; and these points or roots of

time are called _Æras_ or _Epochas_. The most remarkable _Æras_ are

those of the _Creation_, the _Greek Olympiads_, the building of _Rome_,

the _Æra_ of _Nabonassar_, the death of _Alexander_, the birth of

CHRIST, the _Arabian Hegira_, and the _Persian Jesdegird_: All which,

together with several others of less note, have their beginnings in the

following Table fixed to the years of the _Julian Period_, to the age of

the world at those times, and to the years before and after the birth of

CHRIST.
