What is traditional astrology?

 “Traditional Astrology” is the sum of all branches of astrology before the 1700s, especially in the Western world which also includes Hellenistic Astrology, Medieval Astrology and Renaissance Astrology.  

Traditional Astrology is divided into three different periods. First of them is the “Hellenistic Astrology” or “Ancient Greek Astrology” which emerged following the discovery of horoscope astrology and which included everything written in Greek and Latin and has been efficient until the 5th century. The second is the “Medieval Astrology” which represented the development of Greek Astrology by the Arabic, Persian, Muslim and Jewish astrologers and their works embraced by the Latin world. The third is the “Renaissance Astrology” starting from the 1500s when the medieval knowledge was reformed and lasted till the 1700s.

During the Traditional Astrology lessons, we will start with the 1st century AD and give samples from the approaches and techniques of Manilius, Dorotheus of Sidon, Cladius Ptolemy, Vettius Valens, Julius Firmicus Maternus and Alexandrinus Paulus. We will particularly work on the techniques of Masha’Allah, Omar Tiberiades, Abu Ali Al-Khayat, Abu Ma’shar, Al-Kindi, Al-Qabisi (Alcabitius), Zahel, Haly, Abenragel, Al-Biruni, Ibn Ezra and Guido Bonatus. We will also see the techniques used in Renaissance Astrology by    Johannes Schöner, Jean Baptiste Morin, Jerome Cardan, Henry Coley and William Lilly. Within this wide range, we will mainly deal with the techniques of Medieval Astrology.

Why should we learn traditional astrology?

Traditional astrology techniques provide us the talents to delineate the objective reality of the native, his primary motivations and his life events like marriage, births and characteristics of his children; his profession, finances, health, family, spiritual life and to analyse all parts of his existence and to make predictions for the future. The key of an accurate prediction depends on the good analysis of the celestial map. Therefore, how to analyse a chart accurately should be learnt throughly.

The techniques of traditional astrology are consistent and technical. Traditional astrology sets up the rules for the chart analysis and predictions are based on this analysis. It predicts the general flow of the life; first divides it into big parts and then divides these parts into smaller time periods. This represents a deduction approach.

When we learn how to read our chart accurately, we may give up pushing the limits which make us unhappy and through the discovery of our true potential and talents we may see in which fields of life we may find happiness and success. Consequently, we may save time and tend towards right directions. Through accurate analysis, we may see the path we follow, what is expected in the future, when we will be successful or unsuccessful or we may determine the right timinig for our initiatives.

Through the help of traditional astrology techniques, we may make accurate analysis and accurate predictions. However, we should not expect a total precision in these predictions because our knowledge is limited; we may only make prediction but only God knows what will happen. Anyone who is occupied in astrology should know his place and limits.

What are the differences between Traditional Astrology and Modern Astrology?

Below, you may see the differences between the traditional astrology and modern astrology in terms of general approach and techniques. Here, I just want to specify the differences between these two, not to ascertain which of them works best.

* The main difference between traditional astrology and modern astrology is that as modern astrology deals with the native’s psychology, it approaches the chart as an entity which is only related with the native. However, according to traditional astrology the instruments in the native’s chart are not only related with the native’s personality or his belongings because the significators related with the native are the sign in ASC, the ruler of the ASC and the planets placed in the 1st house. Planets which make an aspect with the ASC degree also signify the native’s personality. Consequently, other planets represent the other people and the events in the native’s life, not his personality. Predictions are also based on this rule because in traditional astrology predictions may only be made through determining the significators. Traditional techniques focus on objective realities, not on psychological development. Predicting who or what will be influenced when certain impacts occur is important. That’s why, delineation of the houses is also important in traditional astrology. For instance, when we are talking about the 7th house, traditional astrology is not concerned with the relations or the marriage of the native as modern astrology does. Traditional astrology is concerned with if the native will marry, what kind of a person he would marry with, how will his marriage be, if he would be happy in his marriage and the possible consequences of this marriage.

* Modern astrology considers the chart as a whole. Traditional astrology focuses on different areas of life and determines some special significators, like significators related with marriage, children, career, health or finances, in order to find out possible situations which may occur in different areas of life.

* Traditional astrology is not primarily concerned with the aspects between the planets and other planets or reference points of the chart; this is a secondary approach in traditional astrology. However in modern astrology, aspects carry primary importance. In traditional astrology, it is important if an aspect is separating or applying. This approach, which is crucial in Horary Astrology, is also used in Natal Astrology. Modern astrology is not concerned with if an aspect is applying or separating. In modern astrology, aspects have certain tolerances, whereas in traditional astrology tolerances are only valid for the planets not for the aspects.

* In traditional astrology there are no psychological analyses but there are character analyses which are not indepth analyses as they are in modern psychology. For example, in traditional astrology charts are not categorised with their patterns (locomotive, bucket, bowl, etc.). In modern astrology, chart patterns are used in order to understand the native’s psychology and his interests in differenf areas of life. Similarly, Moon phases (new moon, full moon, balsamic moon, etc) are also important in modern astrology to find out the native’s tendencies whereas these are not used in traditional astrology.

* In traditional astrology Ptolemic aspects, which are sextile, square, trine, opposition and conjunction are used whereas in modern astrology minor aspects are also taken into consideration (especially semi-square (45°), sesquiquadrate (135°) and quincunx (150°). Additionally, aspect patterns like T-square, Grand Square, Grand Trine and YOD are not included in traditional methods. However, in modern astrology interpreting these aspect patterns are especially important.

* In modern astrology, a planet which is combust or void of course does not carry a distinctive feature. On the other hand, in traditional astrology it is a vital detail.

* In modern astrology, there is no distinction between a diurnal and a nocturnal chart while traditional astrology starts the analysis of a chart considering if the chart is a diurnal or a nocturnal one. Determining the Arabic Parts is also primarily related with if the chart is diurnal or nocturnal.

* Astrologers before the modern age, who were traditional astrologers, did not know Uranus, Neptune and Pluton. On the other hand, in modern astrology these three planets which are called “Generational Planets” and Chiron are highly important in chart interpretation. In modern astrology, and especially lately, asteroids, which were not used in traditional astrology, are also referred in interpretation. Similarly, Hypotetical Planets were not known in traditional era, while they are used in modern astrology. In traditional astrology, only traditional instruments were used: seven traditional planets, Lunar Nodes, Arabic Parts, full moon and new moon degrees before the birth (syzygy or SAN) and fixed stars. On the other hand, most of these instruments are not used in modern astrology or they are used differently then they were in ancient times.

* In traditional astrology, we see that the qualities of the signs are listed instead of making interpretations about them. In ancient texts, we see that there are information on signs about their nature, their style while taking an action, and their physical contributions. On the other hand, in modern astrology elements of the signs are used to delineate the personality of the native. 

* In modern astrology Secondary Progressions and Solar Arc are crucial prediction techniques. These techniques were not used during the period when traditional astrology was used. We may see Secondary Progressions in Placidus di Tito’s book named “Primum Mobile” for the first time but this technique has been used during the modern astrology period. Traditional astrology used Primary Progressions, Profections, Directing by Terms and Firdaria techniques which are not frequently used in today’s world. Transits are primarily used in modern astrology while they were only used after other techniques in traditional astrology.  

* Modern astrology tends to place a high value on personal freedom and voluntary or unconditional choices of the native. From the persperctive of modern astrology, prediction is in only possible if it is expressed in terms of learning, growth, transformation and objective attitudes. On the other hand, according to traditional astrology, we are only free within certain limits and we may predict future as we may not exceed some limitations determined by our birth charts. From the traditional perspective, the human character does not change but we may only learn how to comply with the changing conditions.

Why should we learn traditional techniques first?

Traditional astrology is rooted in ancient knowledge whereas modern astrology includes the knowledge that started shaping since the latest century. In historical development process, an improvement form the old to the new is logical. Learning astrology starts with learning the methods of traditional astrology. Through a sound and methodical astrology education, advanced techniques and modern methods may be built on a solid basis. Traditional knowledge helps us delve into the origins of modern techniques and it also helps us preserve the prediction techniques, which may only be used with a detailed analysis of the chart, amongst the intensive psychological concepts and the modern currents.

I do not think we should only use the traditional techniques and put modern techniques aside. On the contrary, we should make use of traditional texts and use modern techniques on this basic knowledge skillfully.

Course Schedule

The first part of the course, which will last for 28, is the Delineation part which will consist of 12 lessons. The second and third parts, Significators and Prediction parts, will consist of 8 lessons each.

The most important contribution of traditional astrology prediction techniques, which provides a stable method, is to allow us define the events objectively that the native may face with. Traditional techniques help us to see and understand the impacts of fate in our lives. The reason that we may see the general flow of our lives together with many details depends on this system and order of fate. We may clearly observe how this system works in the celestial maps. Themes and events of our lives are generally out of our control. This is why we may easily predict many future events accurately. Traditional astrology techniques are consistent and technical. It sets up the ruled for delineation of a chart and for the predictions. For accurate predictions, what the chart promises should be determined.

The fields that attract the attention of the astrologers while determining the main significators in a chart seem to differ rom the ancient astrologers. The main difference of traditional astrology from modern astrology is that it attributes the planets in a chart to other people in the native’s life, not the native himself. After learning the factors which are important in chart reading, significators should be determined. For instance, for marriage we do not only look at the 7th house and its ruler. Or, for career and professional matters we do not only consider the 10th house and its ruler. There are many other additional significators.
