According to Irish mythology, the mysterious Ogham alphabet was invented by Ogma, the Celtic god of eloquence, learning, and the Druids. Because each letter takes the name of a tree venerated by the Celts, it has also been called the “Tree” alphabet. Letters were composed of straight or slanting lines, incised onto the edges of wooden or stone blocks.
