composed on the base of astronomical calculations regarding the
years, months and weeks in relation to the countries, regions
and most of the cities and villages in all Europe and Africa and
part of Asia...
composing process of the quatrains
The first two fragments from the letter to Cesar show which elements
played a part in the composing process of the quatrains.
Nostradamus got revelations, visions. In the investigation on which Nostradamus,
astrology and the Bible
is based, these revelations were called "imaginations". They
contain the nature of the forthcoming events and, as he wrote to Cesar,
details about the locations, such as buildings, bridges and the like.
Nostradamus completed the imaginations with what he called
"inspiration". One can only guess the nature of this inspiration.
This might have been mythology or history.
Nostradamus also completed the imaginations with mundane or judiciary
astrology. This is the kind of astrology which deals with all what
happens in the world in the broadest sense.
fragment of the letter to Henry II shows the functions of mundane
astrology. By mundane astrology, Nostradamus determined which countries,
regions, cities and villages would be involved when the imaginations
would be fulfilled. The second function of mundane astrology was to unveil
the fulfilment data of the forthcoming events. This means that
Nostradamus used a progression system. This is the CD4-system, the
system in which one degree of motion of the Caput Draconis equals four
means that the zodiacal longitudes, mentioned in the quatrains, occurred
during his life in a relatively short period, compared with the time
span of the quatrains (2242 years).
horary chart system: the composing data of the quatrains
The third fragment from the letter to Cesar shows that Nostradamus
got the imaginations between sunset and sunrise. This is also written in
numerous other lines in the letters to Cesar and Henry II.
The imaginations do no contain information about where and when events
will occur. Nostradamus got this information by applying mundane
In the investigation on which Nostradamus,
astrology and the Bible is
based, the astrological method of Nostradamus is called the "horary
chart system". The basic idea behind this system is that
Nostradamus, after an imagination, calculated a horary chart. With this
chart, he determined where and when the events which he saw, would
occur. The hour of the horary chart was the hour on which he got the
imagination. The coordinates of the horary chart were the coordinates of
the place where he was when he got the imagination.
The investigation on which Nostradamus,
astrology and the Bible
is based, showed that the zodiacal longitudes which are mentioned in the
quatrains, occurred between October 16, 1524, and February 27, 1554.
This period is called the "imagination period". There are 19
quatrains which contain enough astrological references to determine the
configuration date. These quatrains are called the "horary chart

Nostradamus got more than 900 imaginations and wrote them down in
the shape of quatrains. A part of the quatrains can be put in
chronological order by applying the horary chart system and the

the sequence of the quatrains is caused by the motion of the planets in
the zodiac. This means that Nostradamus got the imaginations in
chronological order and later, in his book, arranged then at random.
references in the quatrains
Application of the horary chart system makes it possible to some
extent to analyse astrological references in the quatrains. However,
such an analysis will never be sufficient.
The information in the quatrains is too much insufficient to derive when
and at what time Nostradamus got the imaginations on which he founded
his predictions. It is not possible to derive the exact location
where he was when he got an imagination. In the imagination period,
there were four periods of wandering and traveling: 1521-1529, 1532-1533,
1538-1544 and 1547-1551. If the date of an astrological reference is in
one of these periods, it is not possible to determine where Nostradamus
was at that date.
Nostradamus studied in Montpellier from October 1529 until 1532. He
lived and worked in Agen from 1533 until 1538. He worked in Marseille in
1544. In May 1546, he worked in Aix-en-Provence. Later that year, he
settled in Salon-de-Provence. IF the date of an astrological reference
is in one of these periods, the horary chart is calculated for the place
where he lived. It is however possible that he was on an entirely
different location at the time of an imagination.
some kinds of mundane astrology, the standard is to predict what will
happen in he world, when it will happen and in what time span (pre- and aftereffect)
on the base of full aspects (conjunctions, squares, oppositions). In the
case of the quatrains, however, the "what" is not determined
by astrological aspects, since it is revealed by imaginations. This
means that whenever an astrological aspect is mentioned in a quatrain,
this aspect is not always a full aspect. It also means that it is not
always the case that the astrological configuration which is involved,
contains an aspect. The imagination does not coincide with the
appearance of an aspect (full or not). This means that the references in
the quatrains must be analyzed carefully. For example: quatrain 01-52.

the first line, a Mars-Saturn conjunction in Scorpio is mentioned. In
the imagination period, this conjunction occurred only once: on January
31, 1542, 01:58:43 GMT. These facts were supposed to be the composing
date and the composing time of this quatrain. It is however possible
that a date and/or time is at stake, on which this conjunction was not
yet full or already passed by. January 31, 1542, is in one of the
wandering periods of Nostradamus. It is not known where he was exactly.
a number of quatrains there are not only astrological references, but
also references to fulfilment data. Together, these references must show
the composing data and the fulfilment data. For example: quatrain 08-48.

In the second line, February is mentioned, the month of fulfilment, but
Nostradamus does not mention the year of fulfilment.
In the imagination period, Saturn was located in Cancer from June 7,
1532, until July 20, 1534. In this period, only once a Mars-Jupiter
conjunction occurred: on December 26, 1532, at daytime.
February is the month of fulfilment. In order to determine the precise
date, the composing date was supposed to be December 26, 1532, and a
time moment of 0:00:00 GMT was chosen. On the base of these data, the
zodiacal longitude of the Caput Draconis was calculated. From this
position, the date of fulfilment was calculated: February 10, 2189.
Analysis of the horary
The words "horary chart quatrain" mean that such a
quatrain contains astrological references with which a horary chart can
be calculated, the chart Nostradamus calculated after an imagination.

Rodrigue Brind'Amour (Les premières centuries ou prophéties,
1996), Jacques Halbronn D.Litt. (numerous publications on Internet) and
Wöllner (Das Mysterium des Nostradamus, 1926), are also described.
