| THE OGHAM The Ogham system of divination (often pronounced Owam or Ohm, as in the mantra) was created in about 600 BC and has been used by many different Celtic peoples from that date up to the fourteenth century. Its use survives in the form of folk poetry and there are many who find it an inspiration and guide today. It is a sure and safe road that never falters. The letters of the Tree alphabet were commonly cut as a series of nicks on the edges of squared-up wooden laths or sticks to form strokes across a straight line. A more advanced version made these sticks into a square frame, where each revolved at a touch and became a type of mantra - very similar to a Tibetan prayer wheel. Ogham was also carved on stones, using the edge of the stone as a stem line, with the letters usually reading from bottom to top. Some 360 such stones have survived in Ireland, Wales, southern England, the Isle of Man and Scotland. In the northeast of Scotland the inscriptions are in un-deciphered Pictish Ogham of the Dalriada, or Kingdom of Argyll. Initiates could secretly communicate with each other in Ogham by using it as a sign language. With Hand Ogham, communication could be effected by indicating the finger joints associated with each letter, or by forming the shapes of the letters by crossing fingers. Similarly, Nose Ogham and Shin Ogham used the five fingers of the hand to form the cross-strokes of the letters against the straight line of the nose or the shin bone. Obviously more complex ideas connected to the meanings behind the letters could be conveyed, rather than it being merely a matter of spelling. One could quite easily, in front of others, have an ordinary conversation with a person and at the same time send signals that were entirely different. In fact, this system of communication gave the Druids so much power that royal edicts were issued to prevent them conversing in Ogham. |
