ogham

Ogham is an ancient script used primarily for writing in the Early Irish language, believed to have emerged around the 4th to 6th centuries AD. It consists of a series of linear marks or notches, typically carved along the edge of standing stones or wood, representing letters. Each character is made up of a combination of lines or strokes, often grouped by five for easier reference. Ogham inscriptions often served as gravestones or territorial markers, offering insights into early Irish culture and language, and are a significant aspect of Celtic heritage.
