Another god of crafts was Creidne the brazier (Ir. _cerd_, "artificer"; cf. Scots _caird_, "tinker"), who assisted in making a silver hand for Nuada, and supplied with magical rapidity parts of the weapons used at Mag-tured.[261] According to the annalists, he was drowned while bringing golden ore from Spain.[262] Luchtine, god of carpenters, provided spear-handles for the battle, and with marvellous skill flung them into the sockets of the spear-heads.[263] Diancecht, whose name may mean "swift in power," was god of medicine, and, with Creidne's help, fashioned a silver hand for Nuada.[264] His son Miach replaced this by a magic restoration of the real hand, and in jealousy his father slew him--a version of the _Märchen_ formula of the jealous master. Three hundred and sixty-five herbs grew from his grave, and were arranged according to their properties by his sister Airmed, but Diancecht again confused them, "so that no one knows their proper cures."[265] At the second battle of Mag-tured, Diancecht presided over a healing-well containing magic herbs. These and the power of spells caused the mortally wounded who were placed in it to recover. Hence it was called "the spring of health."[266] Diancecht, associated with a healing-well, may be cognate with Grannos. He is also referred to in the S. Gall MS., where his healing powers are extolled. An early chief of the gods is Dagda, who, in the story of the battle of Mag-tured, is said to be so called because he promised to do more than all the other gods together. Hence they said, "It is thou art the _good hand_" (_dag-dae_). The _Cóir Anmann_ explains _Dagda_ as "fire of god" (_daig_ and _déa_). The true derivation is from _dagos_, "good," and _deivos_, "god," though Dr. Stokes considers _Dagda_ as connected with _dagh_, whence _daghda_, "cunning."[267] Dagda is also called Cera, a word perhaps derived from _kar_ and connected with Lat. _cerus_, "creator" and other names of his are _Ruad-rofhessa_, "lord of great knowledge," and _Eochaid Ollathair_, "great father," "for a great father to the Tuatha Dé Danann was he."[268] He is also called "a beautiful god," and "the principal god of the pagans."[269] After the battle he divides the _brugs_ or _síd_ among the gods, but his son Oengus, having been omitted, by a stratagem succeeded in ousting his father from his _síd_, over which he now himself reigned[270]--possibly the survival of an old myth telling of a superseding of Dagda's cult by that of Oengus, a common enough occurrence in all religions. In another version, Dagda being dead, Bodb Dearg divides the _síd_, and Manannan makes the Tuatha Déa invisible and immortal. He also helps Oengus to drive out his foster-father Elemar from his _brug_, where Oengus now lives as a god.[271] The underground _brugs_ are the gods' land, in all respects resembling the oversea Elysium, and at once burial-places of the euhemerised gods and local forms of the divine land.
