Delphic Oracle is a wonderful astrology software.
Not only that it is a software par excellence for Hellenistic Astrology, Delphic Oracle became Astrology software that contains in it many of the techniques used and favored by the Renaissance Astrologers.
I already wrote for one of these techniques, which is not Renaissance technique per se, but was favored and used by Luca Gauricus. This technique is the technique of 13 Monthly Revolutions in a year, of which I wrote here:
In your Delphic Oracle software, you can find this technique by clicking CTRL + D or going into Utilities/Derivative Charts and you will scroll down the list where you can find “Gauricus Monthly Revolution”.
Curtis Manwaring, the author of the software is always open for suggestions and improvements into his software, and this is a characteristic you would rarely find today. You can purchase Delphic Oracle from his site (something I highly recommend if you don’t already have the software) here.
This technique is very old, predates even Firmicus on whom the Renaissance authors like Gauricus and Junctinus rely. Valens used it, and Kolev is of the opinion that goes back to Mesopotamia.
Valens and Firmicus differs in allotting the days to each planet.
According to Valens the year is divided:
Sun……………………………..53 days 20 hours
Mercury……………………….56 days 16 hours
Venus………………………….22 days 16 hours
Moon ………………………….70 days 20 hours
Mars……………………………42 days 12 hours
The logic behind is that the sum of the minimum years of the planets is 129. When the minimum number of years multiplied with 2.83 you will get the above number of days Valens gives. For example, if we multiply Saturn’s minimum years (30) by 2.83 we will arrive at number 84.9.
The reason why we multiply with 2.83 is because when total number of minimum yearsof planets (129) is multiplied with 2.83 we get 365 which is the days of one whole year (Kolev).
But Valens and Firmicus are differing in allotting the days to certain planet, the reason and logic behind Firmicus’ I don’t know at this moment, but it seemed preferable by the later authors, which is again, most probably because Valens’ book was not so popular as Firmicus’ in late medieval and early renaissance period. Although, I am not sure how much truth is in this, because I have found that Gauricus is referring to Vettius Valens on several places in his Opera Omnia.
Firmicus speaks about this technique in Book II Ch. 29:
The days of the whole year are also divided by the individual stars. Moreover, how far they are divided, or from whence they receive their beginning, I shall also take care to show.
When illnesses, when debilities, when gains, when losses happen, when joys, when sorrows. For when the benefic stars receive the days, we are freed from all evil; when malefics, the sudden blows of misfortune strike us.
And so, in whatever sign the beginning of year is, the ruler of that sign receives the first days, and after him the others, according as they are severally placed. And so, which star is allotted how many days – this I shall also tell: the Sun 53 days, the Moon 71, Saturn 85, Jupiter 30, Mars 42, Venus 23 [and] Mercury 57. (Firmicus Maternis – Mathesis, translated by James Herschel Holden, MA)
As we can see, Firmicus gives 30 to Jupiter where Valens gives 34, 36 to Mars where Valens gives 42.5 and then he adds this years to Venus (33) where Valens gives 22.66.
Kolev and Holden noticed the difference but they don’t say the source for Firmicus’ years, nor the logic behind.
At this moment I am not informed too about the same.
Junctinus (1522 – 1580/90) later on wrote that it is better to start from the Lord of the Year but then proceed with the placement of the planets in the annual division (that is, Solar Revolution) instead of as they are placed in the natal chart as Firmicus suggest:
Consequently, the house ruler of the sign where has reached the progression (profection) of the ascendant, is the first to claim the first period of days. After this come the rest (of the planets) exactly as they are positioned in the natal chart – said Firmicus in book 2, chapter 29. However according to my judgment, we should take the distribution of the annual periods from the Lord of the year and after him the other planets as they are positioned in the annual revolution in the order of the zodiacal signs. (translated by Rumen K. Kolev in his translation of Gauricus’ Three Annual Charts for Ferdinand I).
Gauricus (1476 – 1558) in his analysis of Ferdinand’s annual charts uses the exact same technique.
Here’s the annual chart of Ferdinand I calculated in Delphic Oracle:
As you can see the divisions starts from the Lord of the Year, and that is Venus. If you check the Junctinus’ version of Annual Divisions you will get actually Firmicus’ allotment of years, but the divisions following the order of the planets as they are in the Solar Revolution chart as Junctinus, Gauricus, and probably other Renaissance authors propagate.
Gauricus did exactly the same in his analysis of this chart. He said to Ferdinand for example: “you will feel lazy in the rulership of Saturn”, or “you will enjoy with your wife and will take small journeys when Moon rules” (I am paraphrasing) and etc.
Note: Moon falls in 7th house in Gauricus’ annual chart. Calculation of the chart differs here, but my point is to show the order of the planets in the year [which is the same], so neglect the other chart factors.
It is interesting that in the previous year Gauricus used the Monthly Revolutions in his delineation of the year of Ferdinand I, but then, for the next chart of the next year, he shifted into using this technique of Annual Divisions.
So here we are, we have yet another technique on our Astrological disposal. I found out that in order some technique to give good results, one need to apply it on a continual basis, to catch the magic of the technique, that something which is not present in any written form. You can’t say “the technique doesn’t work”. It may be that it doesn’t work for you, but since the technique worked for such a great astrologers as Gauricus – The Prince of Renaissance Astrologers [as some called him without the reference “renaissance” which I add] who had such an amazing predictions, since it worked for Juncinus and Firmicus, and since the technique survived so many years, then there must be something in it.
