Ogham is the earliest written representation of the Irish language. It was created using of a series of perpendicular and intersecting lines. It is thought to represent the Latin alphabet with 20 characters. Over time it evolved adding additional letters and letter combinations. It is most commonly written vertically and is read from bottom to top. When presented horizontally, it is read from left to right.
Though its actual origins remain a mystery today it is believed that Ogham was first used in Ireland and parts of western England, Scotland and Wales beginning in the 4th Century A.D. Its main use was to mark territory by being carved into rocks and trees. Today there are approximately only 400 surviving examples.
For our work we have adopted a 21-letter version of the alphabet, which is considered one of the oldest. Our system includes a "P" missing from the earliest alphabet as well as multi-use characters (F/V, I/J/Y, Q/K, S/X)
