Ogma

Ogma is master of poetry and the supposed inventor of the 'ogham' script, which is said to be called after him.

About the same period flourished the poet Ogma, the traditional inventor of the Ogham alphabet.

And as he was going across the plain he saw three armed men before him, that were the three sons of Tuireann, son of Ogma.

Mao sa guihapon; cun dili saoayon mo caron, dili acó magato-on niana hasta ogma.

Indech was slain by Ogma, who himself died of wounds received from his adversary.
