Each practice is quite as primitive an effort of nature as the Ogham of the Celtic bard.

He used a stone pillar or a wooden stick for his notches,--a more permanent record than the knot or the Indian quipus.[162] The use of a stick as a vehicle for recording ideas by conventional marks, appears very ancient; and this in itself forms a good argument for the antiquity of Ogham writing.

Mr.O'Curry has given it expressly as his opinion, "that the pre-Christian Gaedhils possessed and practised a system of writing and keeping records quite different from and independent of the Greek and Roman form and characters, which gained currency in the country after the introduction of Christianity." He then gives in evidence passages from our ancient writings which are preserved, in which the use of the Ogham character is distinctly mentioned.

One instance is the relation in the _Tain bo Chuailgne_ of directions having been left on wands or hoops written in Ogham by Cuchulainn for Meav.
When these were found, they were read for her by Fergus, who understood the character.

We have not space for further details, but Professor O'Curry devotes some pages to the subject, where fuller information may be found.
