Ogham
Glossary · Last updated: 2026-07-26
Ogham is a medieval Irish script where letters named after trees (Beith birch, Luis rowan, etc.) were carved on stones and sticks.
Modern Celtic tree zodiac books borrow tree symbolism from Ogham and folk calendars. Historical Celts did not use a sun-sign column like newspaper horoscopes.
