Oghams celtic stone

Ogham is an early medieval Irish alphabet inscribed on stone monuments, dating from the 4th to the 7th centuries.

About this subject

Ogham (also spelled ogam) is the oldest known form of writing for the Irish language. It consists of an alphabet of 20 letters, organized into four groups of five, represented by lines and notches along a central line, typically the edge of a stone. Most of the approximately 400 known ogham inscriptions have been found in Ireland, but examples also exist in Scotland, Wales, Cornwall, and the Isle of Man, resulting from the migration of Irish settlers.

The primary function of ogham stones was funerary: they marked graves or commemorated important individuals, often recording the name of the deceased and their patronymic lineage. Some inscriptions include references to natural elements, such as trees, suggesting a possible link with Druidic traditions. The alphabet is divided into aicme, or families of letters, each letter named after a tree or plant (e.g., B - Beith, birch).

Although ogham was primarily used between the 4th and 7th centuries, knowledge of it survived in medieval manuscripts, such as the Book of Ballymote (14th century), which describes the characters and grammar in detail. Today, ogham is studied by linguists, historians, and archaeologists as a key to understanding Irish proto-history and the relationships between insular Celtic communities. Ogham stones are considered Irish cultural heritage, and many are protected under national monuments legislation.
