Ogham is Ireland’s oldest known writing system, dating back more than 1,500 years. If you have ever seen strange lines carved along the edge of an old stone, you may have been looking at ogham. But what did those marks mean? Who carved them? Were they gravestones, boundary markers, family claims to lands or something else entirely? In this episode, I speak with ogham expert Dr Nora White about how this ancient writing system worked, where it came from and what it reveals about early Ireland. These short inscriptions preserve some of the earliest evidence of the Irish language, along with names, ancestors, territories and hints of a society changing through migration, Christianity and contact with Britain and the wider world. Ogham may look simple, but it opens a window onto one of the most fascinating and mysterious periods in Irish history.
