Irish Astrology

The Druids were possessed of “… much knowledge of the stars and their motion, of the size of the world and of the earth, of natural philosophy…” 

Julius Caesar

Irish Astrology, also referred to as Celtic Tree Astrology, is the astrological system practiced by the ancient Irish. It is based on a Druid symbol system and not on any of the traditional systems such as Western, Chinese or Vedic astrologies.  The Celtic Zodiac is drawn from the beliefs of the Druids and is based on the cycles of the moon. The year is divided into 13 lunar months, with a tree (sacred to the druids) assigned to each month. Each tree has particular magical qualities whose secret mysteries come from the ancient shamanic alphabet, the Ogram. The origin of this Tree Alphabet is ascribed to the God of Poetry and Eloquence of Celtic Ireland, Ogam. He is also known as the Celtic Herkules.

The Druids were Celtic priests who inhabited much of Western Europe, Britain and Ireland until they were supplanted by the Roman government and later, by the arrival of Christianity.

Some renowned Celtic scholars also noticed, thanks to their vast understanding, that Celtic astronomy paralleled the Vedics. They discovered that the ancient Celtic astrologers used similar systems as those of the Vedic astrologers.

Classical writers such as Cicero, Caesar, Pliny described the Celts as “masters of astronomy”. Even the Romans paid tribute to their astronomy. One of the first to note that the ancient Celts believed the world to be round (not flat) was Martial (c. AD 40-103/4) who himself claimed Celtic ancestry.

The Irish (and the Celts generally) have a long tradition of astrological learning stretching back to a time before Christianity and the incoming of Greek and Latin learning. For too long now this long and rich tradition of Celtic Astrology has been sadly neglected.

It is believed that the Tree’s hold many powers
as it sow’s its seed on our precious earth,It’s also said that trees are the toy chest of souls,
who wait for the right maiden to allot them rebirth.

Celtic Tree Astrology

Celtic Tree Astrology is the astrological system practised by the ancient Irish. It is based on an ancient Celtic symbol system. The Celtic Zodiac is drawn from the beliefs of the Druids and is based on the cyclesof the moon. The year is divided into 13 lunar months, with a tree (sacred to the druids) assigned to each month. Each tree has particular magical qualities whose secret mysteries come from the ancient Celtic alphabet, the Ogram.The Celts envisioned the entire Universe in the form of a tree, whose roots grew deep below (in the ground) and whose branches reached up high (into the Heavens). In time, the Celtic people eventually designated a tree to each of the 13 Moon Phase’s in their calendar, in accordance with its magical properties. As such the Celtic Zodiac is based upon the cycles of the Moon, with the year divided into the 13 lunar months established by the Druid religion.

The Druid religion was based mainly upon an awareness of natural and supernatural energies. These energies were identified with spirits and the Celtic Druids believed that trees were given these spirits, who dwelt within, and were perceived as attributes of the Supreme Being. Thus, trees were considered living entities, possessed with Infinite Knowledge and Wisdom…symbolically representative of the Cycle of Life, Death and Renewal, and symbolically connected with the three planes of existence: mind, body, and spirit. To Christians, it illustrated the essential core of Christian belief where God was the Father, the Son, and the Holy Spirit. For both beliefs, the Trinity Knot symbolized the way in which the three separate essences were vitally interconnected.

On the whole, Celtic societies were based upon the equality and balance between the male and the female…the female Druidesses being symbolized by the Spirits who lived in the sacred trees. Each Celtic Zodiac Sign corresponds to a given tree, a letter of the Ogham alphabet, a Guardian Animal, a Celtic God, and other items such as Gemstones.

The Celtic Zodiac


Celtic Astrology was created by the Druids sometime around 1000 BC. The Druid religion was based on 3 basic strands of belief: the first was to remember their ancestors and the past; the second was to have an understanding of nature so that they could work with it, not against it; and the third was to explore the connection of everyday reality with that of the spiritual realm.In Celtic astrology, the zodiac is based on the trees that the Druids held sacred. It was believed that the trees themselves expressed personal characteristics that could then be associated with particular months of the year. This was done by connecting the tree to a lunar month through the use of the consonants in the Celtic alphabet. 13 of the consonants form the calendar of seasonal magic, and the 5 vowels represent complementary seasonal stations.Unlike the Greco-Roman zodiac, the Celtic calendar has 13 astrological signs based on lunar months. Each month contains 28 days, except the last one (Ruis/Elder) which only has 24. However, the Celtic zodiac isn’t confined solely to the lunar cycle. The Druids split their years into 2 halves: the dark half and the light half to represent the recurring cycle of birth, life, death, and rebirth. As a result the Druids developed a zodiac rooted in both the lunar and solar cycles of life.

The Fabrication of ‘Celtic’ Astrology by Peter Berresford Ellis

The Celtic ‘tree zodiac’ fabrications, the direct result of Robert Graves’ invention of a tree calendar’, have become an almost insurmountable barrier to any serious study of the forms of astrology that were practiced by pre-Christian Celtic society. For fifty years, from the time Graves’ published his book The White Goddess (1946), a veritable industry has been built up among his acolytes, which preach artificial astrological ideas based on Graves’ spurious arguments. Some have even published books on what they fondly term ‘Celtic Astrology’, manufacturing a completely artificial ‘astrological system’.

It has hitherto not been my practice to directly criticize Graves nor his acolytes. As a novelist and poet, Graves’ work is much to be admired and his two-volume study of The Greek Myths (1955) is highly regarded. There is even much in The White Goddess that is praiseworthy. It can be said that Graves’ work is a fascinating attempt at an anthropological and mythological study which, had he had some scholastic advice, might have resulted in an interesting contribution in the mold of Joseph Campbell’s work.

However, when he asked for advice from a reputable scholar in the field of Celtic Studies and specifically Ogham research, he rejected it because it did not support his prefixed notions.  Continue Reading…

Another viewpoint:

In the ancient worlds, the study of astrology was as important as the study of astronomy. Magic and science were not separate disciplines, but part of the same coin. We know the Sumerians, Egyptians and Greeks of the western world all studied the movement of the heavens, along with Eastern and even ancient American scholars. It is upon the foundation of these western traditions that modern astrology is built. One culture that was renown for their knowledge of wisdom, including astrology, were the Celtic Tribes. The Celtic people eventually settled on the British Isles, but originally migrated westerly across Europe. The Druids, the priest caste of these people, held their lore in oral tradition, believing writing to profane sacred text. One must memorize all, including astrology. So unfortunately a complete system of Celtic astrology never survived in anything but a fragmentary form. The first piece of the puzzle was retrieved by Robert Graves, the famous author of the White Goddess. He correlated the thirteen letter Celtic tree alphabet, the Ogham, with a Celtic lunar calendar of thirteen months. Ogham is a system of symbols, sounds and sign language used by druids. Each one represents a whole host of complex associations, based on the imagery of the sacred trees. Trees played an important function in Celtic myth and society. The word Druid comes from the word Duir, or oak, and is believed to mean “one who has knowledge of the oak.”  If you had knowledge of the trees, you had wisdom and magic. Some modern critics have disagreed with Graves’s interpretation, while others have built upon it.


One such author, Helena Paterson from England, gives us an excellent resource, with  The Handbook of Celtic Astrology and the Celtic Lunar Zodiac.

  1. Fascinating! Many Moons ago I gave a talk at the Irish Astrological Society, My interest in all things Celtic springs from my Irish ancestry and I was privileged to meet Olivia ( Fellowship of Isis) – Robert Graves Irish cousin. I also met this great modern day bard in London in the sixties! He will be remembered long after his critics return to dust – his resting place with laurels lies in the ancient building of Westminister Abbey – enough said!

    1. Thank you so much for your comment Helena! Time ‘got away from me’, hence the late reply..

      Sounds amazing that you’ve met the people you mention, and would have loved to have attended the meeting to hear your lecture at the Astrological Society!

      I’ve since had the time to search for your book further, and I must say, will have to purchase that! So intriguing, along with your other books, so I thought I would also add the description and link to it on Goodreads..

      “Discover your lunar self Solar-oriented astrology has dominated Western astrological thought for centuries, but lunar-based Celtic astrology provides the missing “Yin” principle. Explore the Celtic lunar zodiac, where each month is associated with a tree sacred to the Druids. Each tree-sign is broken down into its Celtic mythology and meaning”.

      All the best Helena and Thanks again! 🙂
