The Ogham is said to have been invented by Ogma, a son of Elatha the king of Ireland. Ogma is known as a Celtic God of
literature and married Eton,the daughter of Diancecht the God of medicine.  The Ogham was carved and read from BOTTOM to
TOP (Also carved, occasionally, right to left) along a line. The line symbolizes the trunk of a tree. The tally marks represent
branches.

  Also written as ogam or ogum, it is pronounced "AHG-m" or "OH-ehm." The Ogham served as an alphabet for one of the ancient
Celtic languages. Its exact origin is uncertain. Current understanding is that the names of the main twenty letters are also the names
of 20 trees sacred to the druids.

 A 15th century treatise on Ogham, The Book of Ballymote, confirms that Ogham was a secret, ritualistic language. The Ogham, or
sacred Druidic alphabet, contained hidden secrets for magic and divination. Only the initiated could understand these occult
meanings. The ancient Celts used the Ogham alphabet in performing magick. They also threw divination sticks engraved with the
signs of the Ogham alphabet. Some authors have suggested the existence of a 13-month calendar, which shared some of these
names.

 The Moon is humanity's oldest calendar. Evidence of ancient peoples keeping time by the phases of the moon have been found
carved into rocks and cave walls the world over. The famous tree calendar of the Celts was such a time-keeping device, and, like
other tribal cultures, the Celts found names and associations for their moon which were developed and codified over many years of
ritual and experimentation. Each moon phase was assigned a corresponding tree, each tree being sacred to either feminine energy
and to the Goddess, or to masculine energy and to the God.

  The trees the Druids selected for the thirteen months were already trees that were sources of magick and myth in Celtic folklore.
The ancient Celts had a kinship with trees, which is shown in this magical alphabet and in their tree calendar. Several of the trees
are said to be attractive to faery folk, and others were sources of magick herbs or medicines.Today the counting of the Celtic tree
calendar begins with the full moon nearest Yule. Perhaps it once began with the full moon nearest Samhain since, until the influence
of the Norse, Samhain marked the beginning of the Celtic New Year.

  The Celts believed that many trees where inhabited by spirits or had spirits of their own. This idea most notably applied to any tree
with a strong aura around it. They also believed that certain trees had a healing influence on humans. From this ancient respect for
the power of trees came the expressions 'touch wood' and 'knock on wood'.
Oak, ash, and thorn were called the faery triad of trees. Where they grow together, it is still said that faeries live.

Ogham
For divination, paint or engrave the symbols on one side of some flat sticks. Ice cream sticks or tongue depressors work well for this
purpose. The symbols can also be drawn on cards and read as you do tarot. Choose seven sticks without looking. Concentrate on
your question while holding them in both hands. Then gently toss them on the ground or floor in front of you. The closest sticks
represent the present; the farthest represent the future. Any sticks that touch or overlap have a direct and enhanced influence on
each other.

The Ogham signs may also be carved into candles or used in writing out requests to be presented to the gods during rituals.
