Ogham Acryptographic alphabet used in certain ancient Celtic inscriptions, notably in Britain and Ireland. Each character consists of from one to five parallel strokes, written over, under, and through the line, either upright or sloping. It was one of the means of intercommunication by the Druids both of the continent and of the British Isles.
Ogham (Modern Irish or ; ) is an Early Medieval alphabet used primarily to write the early Irish language (in the so-called "orthodox" inscriptions, 4th to 6th centuries), and later the Old Irish language (so-called scholastic ogham, 6th to 9th centuries). There are roughly 400 surviving orthodox inscriptions on stone monuments throughout Ireland and western Britain; the bulk of them are in southern Munster. The largest number outside Ireland is in Pembrokeshire in Wales.
