Celtic Astrology Tree Signs

(Appearing Originally in Kaleidoscope Magazine)

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 interpretation, while others have built upon it. One such author, Helena Paterson from England, gives us an excellent resource, The Handbook of Celtic Astrology and the Celtic Lunar Zodiac. Her system uses the Celtic information in conjunction with traditional western astrology, giving us an even broader view.

Much like your traditional Sun sign can give you a lot of information, your tree sign can as well. Look to see what tree sign the Sun was in when you were born. I know a few people who relate much better to their Celtic Sign than the traditional zodiac.
