According to legend, Ogham was devised by Ogma Sun Face, the archetypal Celtic father figure and Sun God. Ogma is also the God of communication and writing and is sometimes thought of as the patron deity of Poets and Artists.
The Ogham was used from about 600 BC to 700 AD by Druids and Bards as a secretive language, especially during Roman occupation of Celtic lands, often "spoken" with the fingers across the forearm, nose, or shin. It was a symbolic alphabet, each letter having a host of ideas and thoughts associated with it. Examples of the Ogham can still be seen on ancient stones, where it was carved using the edge of the stone as the center line.
The sayings on these pieces have been translated into Gaelic and then to Ogham. Each piece also comes with a brochure showing the Ogham alphabet and the meanings associated with each letter.
