The ancient Roman and Greek astrologers had a very peculiar dasa system of their own. It was called the Chronocrator which means the ruler of time. This system is completely unlike any of the well known dasa systems from Hindu astrology. But in the western countries nobody seems to remember anything about the Chronocrator anylonger. So obviously the ruler of time got lost in time...
Anyway, the use of this simple and yet very unique system is described in a detailed manner in a book called the Mathesis from the forth century A.D. written by a roman astrologer by the name of Julius Firmicus Maternus. We can learn it all from this book.
There are only seven planets in the ancient Roman and Greek astrology since Rahu and Kethu were not included. Further, any doubt about whether to use Tropical or Sidereal system with this system is out of the question as this kind of dasa system is not in any manner related to the signs.
The major periods
One by one each of the planets becomes the ruler of time following the order in which they are placed in the birth chart of the native. Thus, if we have Moon in Taurus, Mercury in Cancer and Venus in Leo, then Moon would be followed by Mercury and Mercury by Venus and so on with the major periods of the remaining planets.
According to Mathesis the first period will always be the Sun in a diurnal chart, and the Moon in a nocturnal chart. Experiments, however, seem to show that the system should always begin with the Moon. This may be a matter of further research.
The minor periods
Each of the planets holds dominion for ten years and nine months - equal to 129 months. Each of the major periods are further divided into seven minor periods of unequal duration:
Sun 19 months
Moon 25 months
Mars 15 months
Mercury 20 months
Jupiter 12 months
Venus 8 months
Saturn 30 months
The order of the seven minor periods will follow the order of the planets in the natal chart just like the major periods. But the first minor period in each major period will always be that of the planet ruling the major period itself.
Predictions from the major periods
According to the Mathesis, the major periods controlled by the luminaries always have a bad prediction. If the Moon is warning or any of the luminaries combine with Mars and Saturn it is even worse, but the benefic influence of Jupiter mitigates the evils. However, by the malefic influence of Saturn and Mars they will be aggravated. This is also the case with the other planets.
The Sun's period disturbs the order of life and also indicates illness, pains in the eyes, fever or troubles from fire. The Sun will give a quarrelsome time, and there may be disagreement about house or properties. Also it gives a bad prediction for the father and for the position of the native.
In the Moon's period life is changeable and disturbed in various ways. Something that has been collected earlier is lost again. There will be disturbance of hidden jealousy. There will be anxieties due to accusations and litigations. There will be cold effect to body and mind. Also illness, weakness of body and danger from water.
The period of Mars will change the order of life and occupation. Whatever was carried on before is transferred into something else. The position held before may be lost, or there will be crises. It indicates important steps in occupation with powerful disturbances. There will be some loss of income, quarrels, financial troubles and maybe even dangers.
In general Mercury is a period of joy and happiness. There will be nice profit and suitable income in occupation. There will be protection and friendship with important people. Promotion and fortune are likely in most of the duties and activities. Business affairs turn out prosperously with fortunate outcome. But normally this comes only after labour and troubles. This period also promotes some old disagreements and revives hidden quarrels. There will be certain dangers from things written. Deceit or forgery is indicated. But often the enemies or opponents are destroyed in various ways.
The period of Jupiter indicates good fortune, happiness and glory. Also it brings increase of income, honour and prosperity. Events of marriage or birth of children is likely if the chart and the age of the native permits. The affairs turns out well and there will be nice profit. There will be a happy time, free from all disturbance, and traces of evil are washed away in this period.
Venus is a happy time that often leads to romance. Either in shape of marriage or as illicit love affairs. But promiscuous intercourse and adultery may lead to some hidden scandal. This will be a time of personal charm and grace, freed from many previous misfortunes and troubles. There will be more fortune, happiness and security, and there will be prosperity and profit in most affairs.
Saturn will be a period of slow progress, delay, difficulties and hinderance in the important activities. It may lead to failure in occupation and in the domestic matters. Something goes wrong. This period promotes quarrels. There will be loss of some persons useful to the native. Either by death or by separation. There will be certain breaks in the relations. If danger has been indicated by Saturn, then whatever he had indicated before it will be more severe.
