The Hyleg, Alcoccoden and the Length of Life in Ancient Astrology
Astrallis has been created with ease of use in mind, regardless of the inherent complexity of the subject. Mundo and Zodiacal Conjunctions, Directions to the Angles, Mundo Parallels, Mundo Rapt Parallels, and many other variations have been extensively tested and merged into a consistent software designed with speed and accuracy in mind.

Astrallis has a complete set of timing Keys (including Ptolemy, Placidus, Morinus, Naibod, Kolev, Kepler, and others). Calculations can be switched on the fly between Ptolemy, Pole Placidian, and Regiomontanus algorithms. Additional techniques, as they were formulated during the classical period until the seventeenth century, namely Secondary Directions, Progressions, Solar Returns, Transits, and Ingresses are also calculated and used to find the precise time at which a direction will be effective.

Rectifications are always automatic. It takes just a double-click to recalculate all Charts, Directions, Transits, Ingresses, and Progressions based on a rectified birth time. As soon as an event time changes, everything is recalculated accordingly. For more information about all available options please visit Features.
Welcome to Astrallis, home of the best software designed to calculate Primary Directions, the most ancient, powerful, and reliable predicting tool of Western Astrology since Ptolemy's time. Our goal is to offer a dependable and user-friendly astrology software ready for all your forecasting needs.
The earliest reference to Primary Directions in the Western world date back to the first century A.D., when Doroteus of Sidon gave some examples in his Carmem Astrologicum. One century later, Ptolemy, the famous Alexandrian scholar, was the first to explain different types of directions and the notion of 'similar places,' which is the basic idea behind the well-known semi-arc method. His famous Tetrabiblos was considered the undisputable source for astrologers until the fifteenth century, when Regiomontanus proposed a new method based in spherical trigonometry. Most astrologers from this period, like Morin and Lilly, adopted the new Regiomontanian system because it appeared to be a very 'elegant' and 'rational' solution, even though everybody admitted there was no 'perfect' trigonometrical solution for two 'similar places' having the same relation to both the horizon and the meridian at the same time.

Another two hundred years passed before Placidus de Titis managed to explain almost every kind of primary direction and proposed a clear method of calculation, developing his method of Secondary Direction
s and Progressions to supplement and support the main (Primary) directions.

In his book
Primum Mobile, Placidus contradicts most of the Regiomontanian system and declares he is a faifthful follower of "Ptolemy and reason." Synthesizing his theories in 42 Canons, he presents his ideas "trying to prove the true of things by example," which he certainly did in the last part of his work. Under this premise, an astrologer's reputation was linked to its ability to calculate, forecast, and understand upcoming events using Primary Directions.

Both Placidus and Regiomontanus' methods produce similar results and require a good knowledge of mathematics, astronomy, and astrology. Calculating primary directions by hand is a time-consuming task and generally prone to error. If rectifications, Secondary Directions, and Progressions are included, it becomes a challenge. The choice of one of the two methods was determined, in most cases, by the availability of astronomical and mathematical tables rather than by the quality of the results.

A renewed interest in Astrology around the nineteenth century came together with a questionable and distorted simplification of the original theories, replacing the traditional practice and calculations of Primary Directions with a new and combined definition of Progressions and Secondary Directions, which was quicker and easier to calculate. As a result, Astrology drifted from its original course and lost its standing as a predictive art, falling into the so-called modern astrology of the twentieth century, which, for the most part, ignores its ancient lineage and only provides
character analysis, trend analysis or karmic relationship reports based on robotic and computerized interpretations.

Fortunately, nowadays there is a new interest in the original art of predictive Astrology.
Astrallis' main goal is to provide a complete, reliable, and consistent set of predictive tools, including Primary Directions, Secondary Directions, Progressions, Solar Returns, Transits, and Ingresses as they were explained and practiced by Placidus and Regiomontanus.

Astrallis has been extensively tested and its results have been compared with the works of Placidus, Morin de Villefranche, Sepharial, and others in order to verify exactness and scope.
