The parentage of Lug is differently stated, but that account which makes him son of Cian and of Ethne, daughter of Balor, is best attested.[311] Folk-tradition still recalls the relation of Lug and Balor. Balor, a robber living in Tory Island, had a daughter whose son was to kill her father. He therefore shut her up in an inaccessible place, but in revenge for Balor's stealing MacIneely's cow, the latter gained access to her, with the result that Ethne bore three sons, whom Balor cast into the sea. One of them, Lug, was recovered by MacIneely and fostered by his brother Gavida. Balor now slew MacIneely, but was himself slain by Lug, who pierced his single eye with a red-hot iron.[312] In another version, Kian takes MacIneely's place and is aided by Manannan, in accordance with older legends.[313] But Lug's birth-story has been influenced in these tales by the _Märchen_ formula of the girl hidden away because it has been foretold that she will have a son who will slay her father. Lug is associated with Manannan, from whose land he comes to assist the Tuatha Déa against the Fomorians. His appearance was that of the sun, and by this brilliant warrior's prowess the hosts were utterly defeated.[314] This version, found in _The Children of Tuirenn_, differs from the account in the story of Mag-tured. Here Lug arrives at the gates of Tara and offers his services as a craftsman. Each offer is refused, until he proclaims himself "the man of each and every art," or _samildánach_, "possessing many arts." Nuada resigns his throne to him for thirteen days, and Lug passes in review the various craftsmen (i.e. the gods), and though they try to prevent such a marvellous person risking himself in fight, he escapes, heads the warriors, and sings his war-song. Balor, the evil-eyed, he slays with a sling-stone, and his death decided the day against the Fomorians. In this account Lug _samildánach_ is a patron of the divine patrons of crafts; in other words, he is superior to a whole group of gods. He was also inventor of draughts, ball-play, and horsemanship. But, as M. D'Arbois shows, _samildánach_ is the equivalent of "inventor of all arts," applied by Cæsar to the Gallo-Roman Mercury, who is thus an equivalent of Lug.[315] This is attested on other grounds. As Lug's name appears in Irish Louth (_Lug-magh_) and in British Lugu-vallum, near Hadrian's Wall, so in Gaul the names Lugudunum (Lyons), Lugudiacus, and Lugselva ("devoted to Lugus") show that a god Lugus was worshipped there. A Gaulish feast of Lugus in August--the month of Lug's festival in Ireland--was perhaps superseded by one in honour of Augustus. No dedication to Lugus has yet been found, but images of and inscriptions to Mercury abound at Lugudunum Convenarum.[316] As there were three Brigits, so there may have been several forms of Lugus, and two dedications to the _Lugoves_ have been found in Spain and Switzerland, one of them inscribed by the
