The Ogham Alphabet /// Primitive Irish

“Ogham, quite delightfully, is one of the few alphabets written and read vertically from the bottom to the top.

Its twenty letters, called feda (= ‘trees’), group into four aicme (= ‘family, tribe’) of five letters each.

Each letter is simply a cluster of one to five straight lines, scratched along the (usually) vertical edge of a stone.”
