Another son of Brigit's was Ogma, master of poetry and inventor of _ogham_ writing, the word being derived from his name.[255] It is more probable that Ogma's name is a derivative from some word signifying "speech" or "writing," and that the connection with "ogham" may be a mere folk-etymology. Ogma appears as the champion of the gods,[256] a position given him perhaps from the primitive custom of rousing the warriors' emotions by eloquent speeches before a battle. Similarly the Babylonian Marduk, "seer of the gods," was also their champion in fight. Ogma fought and died at Mag-tured; but in other accounts he survives, captures Tethra's sword, goes on the quest for Dagda's harp, and is given a _síd_ after the Milesian victory. Ogma's counterpart in Gaul is Ogmíos, a Herakles and a god of eloquence, thus bearing the dual character of Ogma, while Ogma's epithet _grianainech_, "of the smiling countenance," recalls Lucian's account of the "smiling face" of Ogmíos.[257] Ogma's high position is the result of the admiration of bardic eloquence among the Celts, whose loquacity was proverbial, and to him its origin was doubtless ascribed, as well as that of poetry. The genealogists explain his relationship to the other divinities in different ways, but these confusions may result from the fact that gods had more than one name, of which the annalists made separate personalities. Most usually Ogma is called Brigit's son. Her functions were like his own, but in spite of the increasing supremacy of gods over goddesses, he never really eclipsed her. Among other culture gods were those associated with the arts and crafts--the development of Celtic art in metal-work necessitating the existence of gods of this art. Such a god is Goibniu, eponymous god of smiths (Old Ir. _goba_, "smith"), and the divine craftsman at the battle of Mag-tured, making spears which never failed to kill.[258] Smiths have everywhere been regarded as uncanny--a tradition surviving from the first introduction of metal among those hitherto accustomed to stone weapons and tools. S. Patrick prayed against the "spells of women, smiths, and Druids," and it is thus not surprising to find that Goibniu had a reputation for magic, even among Christians. A spell for making butter, in an eighth century MS. preserved at S. Gall, appeals to his "science."[259] Curiously enough, Goibniu is also connected with the culinary art in myth, and, like Hephaistos, prepares the feast of the gods, while his ale preserves their immortality.[260] The elation produced by heady liquors caused them to be regarded as draughts of immortality, like Soma, Haoma, or nectar. Goibniu survives in tradition as the _Gobhan Saer_, to whom the building of round towers is ascribed.
