THE COSMOLOGICAL CIRCUMSTANCES AND RESULTS OF THE ANNO DOMINI
INVENTION: ANNO MUNDI 6000, GREAT YEAR, PRECESSION, AND
END OF THE WORLD CALCULATION
ABSTRACT
The Anno Domini yearly count, invented in the beginning of the 6th century, were influenced
by mixture of ancient world concepts, astronomical aspects, calendrical cycles, and
apocalyptic teleology.
AD counts the years since a date of Christ’s fictitious incarnation at the former annual vernal
equinox on 25th March and was presented by Dionysius Exiguus as a new Easter computus
titled “CYCLUS DECEMNOVENNALIS DIONYSII”. AD was invented, because the
Cosmic Year 6000 of Julius Sextus Africanus’ chronicle was reached and caused end-time
fever. Basied on doctrines of late antiquity like the Great Year with the eternal return,
millennialism, the Gospels, and the Apocalypse the AD years focused on the world’s end at
an alignment of all planets in year 2000 of the newly invented count. The date of Christ’s
incarnation was adjusted by the medieval value of precession 2000 years before that
alignment.
This article is a work in process of the book STARTIME (Rothwangl, soon published) and
demonstrates that the dating of Christ’s incarnation by the Anno Domini Years is the result of
a cosmological and astrological quest for the world’s end in the world view of late antiquity
and early Christianity. The aim of the quest was to find a future alignment of all classical
planets, which would mark the end of the world according the Great Year doctrine. After
having forecast such an alignment, due to the astrological concept of the precessional ages
2
and by the medieval constant of precession, exactly 2000 years before that alignment the date
of the incarnation by the AD-Years was established.
This also explains why the AD-Years, focusing on the incarnation of Jesus Christ, as
established at beginning of the Sixth century by Dionysius Exiguus, diverge from historical
data, such as the death of Herod the Great in 4 BC, and is not synchronized with early
historiographies.
If we investigate the circumstances and reasons that influenced Dionysius to invent the new
Anno Domini count we find the following facts:
A) The Occurrence of Africanus‘ Cosmic Year 6000, which caused a calendric world`s
end at the beginning of the Sixth century.
The Cosmic Year (Anno Mundi) of Iulius Sextus Africanus is an early Christian temporal
concept based upon interpretation of the Bible, according to which the Lord created the world
in six days, which are equated to 1000 years each.
Ps. 90:4: For a thousand years in thy sight are but as yesterday when it is past, or as a watch
in the night.
2 Peter 3:8: One day is with the Lord as a thousand years, and a thousand years as one day.
Of the Sabbath He speaketh in the beginning of the creation; and God made the works of His
hands in six days, and He ended on the seventh day, and rested on it, and He hallowed it.
Give heed, children, what this meaneth; He ended in six days. He meaneth this, that in six
thousand years the Lord shall bring all things to an end; for the day with Him signifieth a
thousand years; and this He himself beareth me witness, saying, Behold, the day of the Lord
shall be as a thousand years. Therefore, children, in six days, that is, in six thousand years,
3
everything shall come to an end.
And He rested on the seventh day. This He meaneth; when His Son shall come, and shall
abolish the time of the Lawless One, and shall judge the ungodly, and shall change the sun
and the moon and the stars, then shall he truly rest on the seventh day.
Barnabas 15:3-5
To date the moment of creation the lifetime of Jesus and an end-time prophecy were drawn in
comparison:
I John 2:18: Children, it is the last hour; and as you have heard that antichrist is coming, so
now many antichrists have come; therefore we know that it is the last hour.
Writing in the first half of the third century, Origen, in his Commentary on Matthew,
employed the analogy of the twelve hours of the day to divide the whole of biblical history
into ages. Accordingly, he locates Noah at the third hour, Abraham at the sixth, Moses at the
ninth, and, finally, Christ at the eleventh hour. (Declercq, 2000)
The Christian Old Testament (2. Moses 25) tells that the Ark of the Covenant was 2 1/2 cubits
long, 1 1/2 cubits wide, and 1 1/2 cubits high. Irion (Hieron) of the court of Constantinople
and Hippolytus both interpreted these dimensions, amounting to 5 1/2 cubits, as symbolic of
the 5,500 years. (Mosshammer, 2009)
The first Christian Chronography of Africanus (3rd century) used these comparisons to date
Christ’s birth to the year 5500, figuering the fictitious creation in this way:
• The world lasts 6000 years.
4
• Christ came in the 11th of 12 hours,
• 6000 : 12 * 11 = 5500
• Thus Christ came in the year of the world 5500.
Yet the approach of the fatal Cosmic Year 6000 occurring 500 years after Christ’s birth
caused end-time fever among the believers.
At the turn of the fourth to fifth centuries, i.e., precisely the moment when the barbarian
invasions may have stirred up apocalyptic anxieties, the North African bishop Julius
Hilarianus, for instance, wrote a treatise ”On the Duration of the World,” in which he
calculates 5530 years from creation to the Passion of Christ, and 369 years from that event
until the consulate of Caesarius and Atticus (AD 397); there remain, so he concludes, 101
years to go before the Resurrection of the dead. (Declerq. 2000)
To avert end time fever and to sustain religious credibility several strategies were applied by
the church:
A1. Shifting the era of creation to the past in order to show that the dreaded year AM 6000
had long passed, as the chronicler John Malalas did by identifying the year 6000 with the
passion of Christ.
A2. Rejuvenating the age of the world and shifting the year AM 6000 into the future, which
was the method of the fourth century chronicler Eusebius. Influenced by Jerome, Eusebius
delayed the birth date of Christ by three centuries to AM 5199.
5
A3. Starting a new counting of the years from another fictitious point in time: Christ’s
incarnation. Dionysius Exiguus made the most widespread attempt at this when he created a
new temporal hinge point for counting the years: Anno Domini, Year of the Lord.
Dionysius created a new Easter cycle starting with AD 532 and established in this way a new
yearly count, but gives no concrete hint how and why he made his invention.
If we take the narrative of the Bethlehem star of the Gospel as a historical fact, we have the
dilemma that Herod the Great died in 4BC, and therefore the AD years do not represent
precise historical fact and in addition do not go conform with any contemporary chronologies.
The Adjustment of the “anni ab incarnatione Domini nostri Iesu Christi” by Dionysius
Exiguus
…Because the blessed Cyril began his first cycle in the 153rd year of Diocletian and ended
his last cycle in the 247th year of Diocletian, we have to start in the 248th year [i.e. 532 AD]
of this man, who was a tyrant rather than emperor.
However, we did not want to preserve the memory of an impious persecutor of Christians in
our cycles, but chose rather to mark the times with the years from the incarnation of our Lord
Jesus Christ [i.e., 532 AD], so that the commencement of our hope will appear more familiar
to us and the origin of the redemption of mankind, that is the Passion of our Redeemer, will
shine in a more glorious way.
(CYCLUS DECEMNOVENNALIS DIONYSII)
B) Doctrines that influenced Dionysius’ adjustment of AD:
1. The cosmological concept of Antiquity (Great Year)
2. The idea of Jesus‘ return at a conjunction of all planets
6
3. The astrological connection of Jesus with the current new heliacal vernal equinox
constellation Pisces symbolized by the acrostic ICHTHYS
4. The Apocalypse of John of Patmos and its allusion to the seven planets and precession
B1) The Great Year Doctrine of Antiquity
There exist dozens of ancient cites of a common multiple of the planetary periods as for
example Plato tells. This doctrine, called apokatastasis pantoon, was based upon the idea that,
when the planets return to the same position as at the beginning, everything would repeat
itself (Waerden, 1952, pp. 129-155), as Eudemos a pupil of Aristotle tells. From Berossos,
Cicero, Seneca, Heraclitus Stoicus, Macrobius, and Nemesius we have similar citations (de
Calatay, 1996)
... and hence they [humankind] can scarcely be said to know that their [i.e. the planets’, ed.]
wanderings, being infinite in number and admirable for their variety, make up time. And yet
there is no difficulty in seeing that the perfect number of time fulfills the perfect year when all
the eight revolutions, having their relative degrees of swiftness, are accomplished together
and attain their completion at the same time, measured by the rotation of the same and
equally moving [i.e. the equator, ed.].
Plato --Timaeus 39 c-d
There is a common multiple of all orbital times, the large year; at its expiration all planets
are again in the same place.
… If one believes the Pythagoreans, then I will return also in the future, as everything after
its number returns, and I will tell you here again fairy tales, holding this stick in my hand,
7
while you will sit likewise before me. Likewise everything else will repeat itself.
Eudemos, Aristotle’s disciple at the Lykaion at Athens
Men usually measure one year only by using the return of the sun, thus with only one star; but
if however all stars return to the same point from which they started, and repeat in long
intervals the same figure of the total sky, then this is called indeed a "turning year";
Marcus Tullius Cicero, Somnium Scipionis, de Rep. VI,24
The year that is called "mundanus” is a true turning-year since it happens by the turning of
the entire universe, unfolding over the longest periods of time; ... [it] is therefore the end of
the Great Year, when all the constellations and all the fixed stars so return from a known
place to the very same place, that not a single star is in a place other than the one in which it
was when all the others were set into motion from their places;
Macrobius, Somnium Scipionis 2,11,8-11
Berossos, the interpreter of Belus, states that the courses of the planets determine the time of
a fire disaster and a flood. A fire on earth will rage if all planets, which move now in different
courses, will gather in Cancer, standing still in the same place (of the sky), such that a
straight line can pass through all their positions. A flood, however, will come if the same
group of planets comes together in Capricorn.
Seneca, Questiones naturales III 29,1
Some people want the conjunction of the seven planets in one zodiacal sign to be referred to
by these words of Homer, and also the universal destruction, whenever this should happen.
He (Homer) alludes to the confusion of the universe when he brings together Apollo, i.e. the
Sun and Artemis, whom we identify with the Moon, as well as the stars of Aphrodite, Ares,
8
Hermes, and Zeus. In such a way as not to appear to be ignorant, we have to accept this
allegory more for its persuasiveness than for its veracity.
Heraclitus Stoicus, Quaestiones homericae, 53
Also, the Christian scholar, Clement of Alexandria, writes of this periodical purification by
fire and water, and accuses even Plato and the Greek philosophers of being thieves and having
stolen this idea from the Bible:
Plato also states in like manner that the Earth is purified at certain times by fire and water:
“There have been many destructions … the biggest ones by fire and water” …Then, (Plato)
speaking of the flood: “But when the gods purify the Earth by submerging it, those who are in
the mountains, cattlemen and shepherds, are saved, while the inhabitants of our cities are
carried away to the sea by the rivers. I have shown in the First Stromateis that the Greek
philosophers deserve to be called thieves, for they have taken their main tenets from Moses
and their prophets, without any acknowledgement of debt.
Clement of Alexandria, Stromateis, V, 1, 9-10
B2) The idea of Jesus‘ return at a conjunction of all planets
Nemesius gives a report that early Christians believed that during a Great-Year-alignment the
Resurrection of Jesus was expected.
According to the Stoics the conflagration and the destruction of all beings is generated, after
stated periods of time, by the planets, when they come back, both in longitude and latitude, to
the same sign in which each one of them was at the beginning, when the world was first
shaped. Then, from the start the world is restored anew. Since the stars are brought back
9
similarly, everything which occurred in the previous period is accomplished, without any
change. There will be again Socrates and Plato and every man, with their friend and fellow-
citizen. They will suffer the same things, and every city, every village and every field will be
restored similarly. This restoration of everything will not take place once, but many times, or,
more exactly, the same things will be restored indefinitely and endlessly. As for gods who are
not subject to destruction, by having witnessed this single period, they will know all the things
that will occur in the subsequent periods. For nothing will be unexpected regarding the things
which occurred previously, but everything will be the same without any change, even in the
tiniest details.
Some people state that Christians imagine the Resurrection by way of this restoration, but
those are completely wrong. For Christ's words instruct that the Resurrection will take place
once and not periodically. (Nemesius, about 400 CE)
In early Christian iconography the scene of the “Meal of the Seven,” (Fig. 1 and 2) found in
several graffiti at the catacombs of Rome represents this cosmic moment expected by early
Christians at the end of time or in the world beyond. This scene mirrors that sitting together at
a common meal, which alludes to the classical Greek symposium after the creation of
humankind by Prometheus. Figures 3 and 4 illustrate an alignment of the classical planet in
the Ptolemaic and Copernican system.

system (left) and in the modern heliocentric system (right).
B3) The astrological connection of Jesus with the contemporary new heliacal vernal
equinox constellation Pisces symbolized by the acrostic ICHTHYS
Early Christian iconography in catacombs of Rome shows the acrostic ICHTHYS and graffiti
of a fish (Figs. 5 and 6), which alludes to Jesus as the releaser of the new age of Pisces due to
the precession of the equinoxes. As a consequence Dionysius dated the starting point of his
years to the vernal equinox at 25th March, the former feast of Incarnation (now Annunciation).

11
The letters ICHTHYS of the Latinized version of the Greek word IXOYS (fish) was
interpreted as Iesous CHristos THeou HYios Soter (Jesus Christus, son of God, Savior).
Early 3rd century Christian writer Tertullianus alludes to Jesus Christ and the new age.
... we, little fishes, after the image of our ICHTHYS, are born in the water. (Tertullian, De baptismo)
B4) The Apocalypse of John of Patmos and its allusion to the seven planets and
precession.
As the great Franz Boll already states Revelation tells of the future cusp from one aeon to the
next. Thus it tells of the shift from the Piscean age to the Aquarian age.
The material... to interpret the Revelation of John... consists of texts and images. Prophecies
like Apocalypse deal with images of the future. ...The Apocalypses tell of events shortly before
the end of this world, or more correctly said, before or at the beginning of a new aeon or
saeculum. (Franz Boll, 1914)
In the introduction, the Apocalypse gives a hint on how to interpret it astrologically.
If we identify the seven stars with the angels, i. e. the ancient deities of the seven communities
of Asia minor, as Revelation itself says, we easily find an allusion to the seven classical
planets.
[Rev 1:20] As for the mystery of the seven stars which you saw in my right hand, and the
seven golden lamp stands, the seven stars are the angels of the seven churches and the seven
lamp stands are the seven churches.
12
Revelation explains that the seven stars are the angels (deities) of the seven churches and the
seven letters of the Apocalypse are addressed to these seven churches:
Ephesus: Main antique sanctuary of Artemis = Moon
Pergamon: The famous alter of Zeus = Jupiter
Thyatira: The text mentions the morning star = Venus
Sardis: The text deals with merchants and thieves = Mercury
Philadelphia: Greek Delphi is the sanctuary of Apollo = Sun
Laodicea: = Mars?
Thus Apocalypse addresses the seven classical planets and makes an allusion to the value of
Precession:
Rev 13:11] Then I saw another beast, which rose out of the earth; it had two horns like a
lamb and it spoke like a dragon.
[Rev 13:18] This calls for wisdom: let him who has understanding reckon the number of the
beast, for it is a human number, its number is six hundred and sixty-six.
In the Western hemisphere since the end of antiquity the usage of the precessional value 66,6y
each 1° (equal to 666y/10° or 2000y/30°) can be found in the writings of the following
astronomers:
• Theon of Alexandria (4th cent.)
• The tables of the Shah (Zij-i Shah) (6th cent.)
• Al-Khwarizmi, al zij Sindhind (c. 800)
• Tabulae probatae or az-Zig al-mumtan (c. 830)
• Al-Battani, called Albategnius, al-Zij (c. 880)
• al-Sufi, called Azophi (c. 965)
• Al Biruni (973-1048), al Canon al Masud
13
• Arabic fixed star catalogue of 1st Oct. 1112 CE (ed. Paul Kunitzsch)
• Libros del Saber von Alfons von Kastillen (1252-1284)
• Judah ben Verga of Lisbon (c. 1470)
There exists a strong indication that in India the value of 1800y/27° (Bennedik, 2007) was
used even before medieval times (Pingree, 1976, p. 112), which equals 2000y/30°. A transfer
of knowledge from India to the occident occured at the end of antiquity, as ascertained by the
9th century patriarch Photius of Constantinople, as well as by Cedrenus in the 11th century.
During the reign of Constantine in the 4th century, Metrodorus, who created a 532-yearly
Easter cycle, visited India to study philosophy with the Brahmins (Mosshammer 2009, p. 199)
An 8th century illustration of Germanicus’ “On the Phainomena of Aratos” in the Codex
Basiliensis (Haffner, 1997) impressively confirms the mediaeval identification of the feared
apocalyptical beast (Fig. 7) with the upcoming age of Aquarius and shows the horned beast
just between Pisces and Capricorn, where one usually expects to find Aquarius.

C) Conclusion:
Due to the arrival of the year 6000 in the Anno Mundi of Africanus in a year corresponding to
about 500 AD, which caused end-time-fever, Dionysius Exiguus was searching for a future
date of world’s end. He searched for a future alignment of all classical planets by the hand of
the commensurable planetary periods, similar to his Indian contemporary Aryabhata, who
calculated backwards to such an alignment and dated there the beginning of the Indian age
Kali Yuga. The same year, 3102 BCE, we find later in Persian and Arabic chronologies, such
as Abu Mashar’s “Book of the Conjunctions” where it is identified as the date of the Deluge
(Waerden, 1980, pp. 117-131) and makes evident the transfer of astronomical knowledge
between India and the West. Dionysius Exiguus, after having calculated a future alignment,
adjusted 2000 years before this alignment the starting point of his “anni ab incarnatione I.C.”
It has the effect that on May 5th, 2000 a rare close massing of the classical planets occurred
(Fig. 8). B. L. van der Waerden has calculated a very minimal probability (P = 0.026) that in
an interval of 6000 years, a massing of the classical planets within 30° would occur. Thus it
appears that Dionysius, based on the cosmological (Great Year) and religious (Six Day
Creation, Apocalypse) doctrines of his age, centered his AD years towards the alignment of
the year 2000 because of an expected end time together with the return of Christ.
