Placidus 7: The Ultimate Tool for Ancient Astrology

Released in 2012, Placidus 7 combines Dr. Kolev’s previous Primary Directions and Early Western Astrology modules with a brand-new module for Mesopotamian astrology.

The Primary Directions Module

Drawing on Dr. Kolev's extensive scholarship, the Primary Directions module calculates hundreds of variations of primaries so you can see which systems yield the most accurate event timing. It produces lifetime lists of primaries including one that gives side-by-side comparison of the hit dates produced by 8 different keys (time-arc conversions), including Ptolemy, Cardan, Naibod, Placidus, Kepler, Kuendig, Van Dam, Sun's travel on birthdate, and user-defined. Direction types include Placidian, Regiomontanian and Topocentric, done both zodiacally and in mundo, direct and converse. You can see contacts to angles and cusps, planet-to-planet, and planet-to-itself, by conjunction or aspect, or by in mundo or rapt parallel. Promissors and significators include 170 fixed stars. So that you can integrate them with primaries, there are also the usual natal charts, transits, secondaries, solar arcs, and symbolic directions as well as solar and lunar returns, which you can display in 1- to 4- ringed static or animated wheels. Additional goodies include speculums--Placidus (classic or under the pole), Regio, Campanus and Topocentric, plus one for Alcabitius house cusps.

This module’s other features for off-the-ecliptic astrology include an impressive celestial sphere that shows in mundo relationships in the chart and how they change when points are directed. Selecting from its more than 100 menu choices, you can also use this screen to explore fixed stars, great circles, coordinate systems and houses. There's also a very nice 360-division Gauquelin wheel (a.k.a. Placidus mundoscope) that makes it easy to see parans and in mundo aspects.

The Hellenistic/Arabic/Medieval Module

The “Porphyrius Magus” module enables you to use and compare a very complete range of early astrological techniques. Its innovative chart wheel (which can be static or animated) uses special symbols and color-coding to show the traditional cosmic state of each point in the chart. Menus let you choose points, calculation methods and many other informative windows. These include an All Almutens Wizard that lets you experiment with different ways of calculating the almuten, and a Porphyry Almuten Wizard that lets you specify how a Porphyry almuten is calculated. There’s also a table showing the results of calculating the hyleg, alcocoden and almuten according to 10 different sources, and a Heliacal Phase window that graphs the phases of all the visible planets with regard to the Sun as of the chart date.

The Mesopotamian Module

Dr Kolev’s newest module brings to life the astrology practiced in Mesopotamia from 5500 BC to 70 AD. It is built around an innovative chart form that includes not just the ecliptic but also the horizon and meridian, the zenith and nadir, the three Babylonian celestial paths of Enlil, Anu and Ea, and images of the constellations overlaid by stars with their name and magnitude. On this form the ecliptic circle can show either the Babylonian fixed zodiac, the Babylonian tropical ecliptic (as per the MUL.APIN text), or the tropical Ptolemaic zodiac. As per the Liber Hermetis, each ecliptic degree is shown as lucid, shadowy, dark, or empty. Dodekatemoria can also be shown, as well as the equinoxes and solstices. As an additional overlay, you can put in the cusps for the oktatopon, or “circle of Petosiris,” an 8-fold mundane division that was used much as we use houses. You can switch virtually every feature on and off.

For any star, additional tables show, in all three zodiacal schemes, its position projected in three ways: simple ecliptical, paranatellonta (ecliptical degree that co-rises with the star), and ortus (ecliptical degree of the Sun when the star rises heliacally). Also shown are the star’s altitude and azimuth, RA and declination, days from the first morning appearance of Sirius, and other information.

The Mesopotamian module also computes all four heliacal phases of a star, based not only on the body’s declination and the observer’s latitude, but now also with the addition of a factor for atmospheric extinction. Based on more than 230 first-hand observations, the added atmospheric factor enables you to more closely pinpoint the date when a heliacal rising will be actually visible. Knowing the heliacal risings of the stars, you can determine the star under which a person was born -- the last star to heliacally rise before the person’s birth (called by the ancients “in the crown of the rising Sun”).

In addition, you can work extensively with planetary heliacal phases. You can plot the positions of these phases on the wheel, noting conjunctions to important chart factors. You can also derive information about a planet’s current state by viewing a chart for the exact time of that planet’s last heliacal “birth.” You can do heliacal calculations for any epoch.

Venus is a special case, because it spaces each successive instance of a given heliacal phase evenly around the zodiac in a 5-pointed star pattern. This 8-year cycle is reflected in another important part of Babylonian astrology, the celestial pentagram of Venus. The Mesopotamian module can plot the pentagram on the wheel, showing where it contacts important chart points over an 8-year cycle. As the basis of the pentagram, you can choose from any of the heliacal phases (morning first appearance, evening first, morning last or evening last) and the pentagram will then show the five points in the zodiac where that phase repeats over the 8-year period.

To give an overview of all the important Mesopotamian astrological events in any given year and place, there is a new Parapegma (or heliacal calendar). Arranged chronologically, this lists the dates of the heliacal phases of the planets and stars, plus the lunar phases and solar ingresses occurring during the period.

Yet another chart wheel view is the Sphaera Hermetica. This shows the positions of the planets relative to three ways of calibrating the ecliptic: a) the fixed Babylonian zodiac, b) the tropical Babylonian ecliptic with the equinox at 15 Aries, and c) the 12 or 13 luni-solar months with the equinox in Nisan. An outer ring shows the day and month of the heliacal rise of bright stars, and towards the center there is a ring for each of the visible planets that shows the positions of its recent heliacal phases.

Yet another view, the “2D + Contrast” wheel, divides the zodiac into dodekatemoria, and shows which of the 36 Mesopotamian divinities is associated with each dodekatemorion. This view also shows the year when the spring equinox entered that dodekatemorion. A zoom-up of up to 5 times is possible in this module.

An animated dynamic wheel view enables you to re-create the three main Mesopotamian progression rates: day for a year, two hours for a year, and four minutes for a year.

There’s also an extensive “Various Data” table showing, for each chart point, data such as its visibility, phase, dodekatemorion, dignities, whether it is hayz, and even its gravitational pull on the Earth as of the chart date. You can view the Various Data table either by itself, or placed under the chart wheel in a printout. For Dr Kolev's fuller (pdf) description of the new Mesopotamian features, click here.

Babylonian Astrology

Written prior to the latest Mesopotamian module, Dr Kolev’s Babylonia program enables you get into the mindset of a Babylonian astrologer by tracking the diurnal and heliacal cycles of the planets in any epoch. It includes a static or animated “3D” view of planets and stars as seen from any specified location, rise/set tables and bar graphs showing the daily cycles of the visible planets, and tables and circular diagrams showing the stages in each planet’s heliacal cycle. Dates of heliacal risings are computed accurately using the body’s declination and the observer’s latitude. Babylonia also converts dates to and from the Babylonian (and Jewish) calendar, and it includes data for all 32 extant Babylonian horoscopes collected by Francesca Rochberg. As a bonus, it offers special fast primary directions that Rumen Kolev has used with slower directions to pinpoint events exactly.

Windows 98 through Windows 10, both 32- and 64-bit.
