Athair is the modern Irish word for 'Father' and 'Olathair' is an old Irish name that ties directly with one very singular deity. Olathair is best translated as 'great' or 'ample' father and there is only one God of Ireland that fits both of those descriptors very comfortably. He is an Dagda.
Oghma served the Tuatha Dé Danann as their Champion, bringing his great strength to bear time and again in the challenges that faced his tribe. Yet it was not only the power of his arm by which he served. It was also with the power of his mind.
Before their arrival in Ireland the Tuatha Dé Danann were said to have traveled far and wide, learning all manner of skill, druidry and other occult practices. The power of this tribe was such that their movements were noted in visions of prophecy long before their ships ever graced the skies
One of the most welcomed people in this skilled society were the bard's whose performances added much needed cheer in tales songs and music. Of course there are many who could turn their hand to an instrument, but there were few who could claim true mastery of it.
In ancient times Ireland was ruled by chieftains and kings, but the rule of land was not a birth right. One had to prove ones worth by skill of thought, word and deed even to be considered for such a role. Even those aspirants were not guaranteed to rule for the last, and some might say most important, step in the process was to connect with the sovereignty of the land itself, for only in a union with the Goddesses of the land could a rightful chieftain rule.
The Tuatha Dé Danann came into Ireland as the descendants of those who had emigrated to avoid oppression. They took rule of the land and began to prosper, yet there were dark times in their future. Something which could not have escaped the notice of those gifted in prophecy.
In the time before the Tuatha Dé Danánn came into Ireland there were other tribes in the land and indeed older Gods. Lír is the name of one such ancient deity and he was a being of some importance to the island nation as he was the God of the sea itself. Yet for all of his power and influence, we seem to have no tales about him, but we do have many tales concerning his son, the Mac Lír, known as Manannán.
The creation of this script was as a proof of Ogma's own ingenuity and that the knowing of this should be kept for only the most learned to pursue the truths that the Ogham may reveal. The act of crafting ogham is one of capturing the very essence of a sound, which could also be said as the naming of a thing and binding it to a physical form.
Amongst the Tuatha Dé Danann we find mention of the Badb, or Badhbh in modern Irish. She is listed, along with her sisters Macha and The Mórrígan, as a Goddess of battle and death. Said to take the form of a hooded or scald crow the Badhbh flies over the battle fields of Eireann and that her raucous cries cause the weak of heart to quail in terror.
The Lebor Gabála Eireann, or Book of Invasions tells of the coming to Ireland of the Tuatha Dé Dannan. As this tribe struggled to establish themselves upon the land and then defend it from invasion and war, there was one among the heroes who offered to do all that any other could volunteer. The lore tells us that they called him An Dagda as he was their Great God of druidry and magic.
What deeds could there be had if there were no one to record and remember them? Who would recall the names of the slain in times to come if not for the observation of their passing? Who could stand and gaze into the harming and slaying with a will to see, with a mind to recall every detail, and with a heart that could not be broken?
