Celtic Astrology

Since the beginning of mankind, the sky has been the first tool used to gain knowledge, and Albert Einstein is said to have referred to astrology as the mother of science.

Just as Chinese astrology can differ from ‘ours’ – that is, the astrology we are familiar with in Europe, with the 12 signs of the zodiac, which in fact comes from Egypt – Celtic astrology is also distinct.


It starts from the idea that each person’s life broadly follows a sort of storyline which is set out in their solar birth story or ‘myth’, itself associated with one of the 36 constellations of Celtic astrology. Each of the 36 signs has a myth or legend, in which a person must become immersed in order to fulfil their destiny, in harmony with the forces of the cosmos. Indeed there is a sense that the individual is just one of many actors on an immense stage, each playing his or her role.


Celtic astrology is not well or widely known; there have been very few books written about it, and those that exist are mostly out of print (although these days you can find a good amount of information about it on the internet). This is actually not a coincidence; for thousands of years this knowledge has been passed on from the initiated down to a select and privileged number who were worthy to receive it and who were trained for it all their life. It was passed on orally, like a secret. In the time of the Gauls, it was the druids who possessed this knowledge.


It has reappeared, in our age, and has avoided sinking into oblivion, thanks to a few people who have taken on the task of writing about this subject, whose history reaches back to Neolithic times.


In fact, there is much confusion surrounding its history. The people who built the megaliths lived between 7000 and 2000 BC, well before the arrival of the Celts around 1000 BC in the lands we now call ‘Celtic’, such as Brittany. There is also confusion between the terms Celt, Breton, Gaulois…


So, this form of astrology known as Celtic actually has its roots in prehistoric times, from men who worked with stone, and later metals in the bronze and iron ages. It was around since the first hominid peoples who populated these lands, and continued with the arrival of ‘modern’ man about 50,000 years ago from Africa. This is what astrology is, something which links humanity to nature, and to knowledge and understanding which has existed since the dawn of our existence.

Celtic astrology suggests an interpretation of each person’s birth theme, by connecting the individual’s life to the mythical dynamics within it. A meeting of the heavens and the earth through human conscience. It gives each person the opportunity to play his part in life, alongside others, with the goal of becoming a better being. Each Celtic sign is represented by a constellation, of which there are 36. When presented as a circular chart, each sign rules over ten degrees of the circle, known as a decan.

Celtic astrology is based on the notion of destiny. Rather than escaping or denying one’s destiny, it offers the chance to understand one’s ‘myth’ (a tale in which some trial or adversity is overcome), to meditate upon it and let oneself be guided by it in order to succeed. It is the great game of life, which must be taken up joyfully, and by allowing ourselves to be lead by our understanding, we can control our destiny by ‘becoming ourselves’.

It is the oldest system of symbolic thought which men are still aware of. Its aim is that an individual flourishes in each incarnation, through studying their natal chart marked with the movement of the sun around the earth, which crosses the constellations each year. The aim of this form of astrology is not to make predictions but to interpret consciousness, by experience and through an understanding of the myths. There is no separation between the internal and external world, the visible and the invisible; thought is also part of the framework of the world. Through our personal myth and according to our sign, this astrological approach teaches us how to comprehend the world which surrounds us, our consciousness, and our destiny.

Astrologie Celtique

Although called ‘Celtic’ after the name of the last people group to have used it, this form of astrology is grounded in empirical knowledge acquired over millennia. Its intention is to guide the person whilst leaving them freewill – the person becomes a crossroads, a meeting point between heaven and earth. It interprets life as a series of exchanges between the forces of the universe, reflects on how everything is related and interlinked, and then allows each individual to find their place at each particular moment in time.

The symbolic system of Celtic astrology rests upon the observation of the cosmos, of the trajectory of the sun across the sky during the course of a year, its path crossing the twelve signs of ‘traditional’ astrology. But these ancient peoples also took into account constellations that the sun’s path did not actually cross, but which seemed to have a considerable influence on the spiritual and material order.

The idea was that the arrangement of heavenly bodies, the cosmic order, was a viable and observable model for organising life, and understanding the forces at work in the world and in the individual. So they chose 36 constellations, and divided the year into 36 periods of approximately 10 days and, linking the two, they formed decans. Each decan has a Master, the constellation which is positioned perpendicular to the sun. Each decan is associated with a symbolic legend, which represents certain personality traits. It is also associated with a tree, which gives its name to the decan and exemplifies the myth. The tree is a symbol of life on earth, of the order which rules here, linking it to heavenly realms via the ‘crossroads’ of the individual. And this is in order to live in harmony with cosmic laws which preside over life, in peace and with serenity.
