Ogham script

Ogham is an ancient script used primarily in Ireland and parts of Britain around the 4th to 7th centuries AD. It consists of a series of lines and notches carved along the edge of stones or wood, typically arranged in groups representing letters. Each letter corresponds to a specific tree or nature-related concept, reflecting the Druidic culture of the time. Ogham inscriptions often served as memorials or markers, providing insight into early Celtic languages and traditions. Today, it’s considered an important aspect of Ireland's cultural heritage and is studied in archaeology, linguistics, and history.
