XV. KEEP COOL
There is no doubt about the European character of this tale, which is found in Brittany, Picardy, Lorraine, among the Basques, in Spain, Corsica, Italy, Tyrol, Germany (though not in Grimm), among Lithuanians, Moravians, Roumanians, Greeks, Irish, Scotch, Danes, Norwegians (Cosquin, ii., 50). The central idea of the Rage-Wager is retained throughout, and in many places the punishment is the same—the loss of a strip of skin. In all but three instances the story is told of three brothers, which practically proves its identity. I have given the Irish version in More Celtic Fairy Tales.
The "sells" however change considerably, though in most of them the final dénoument comes with the death or wounding of the wife. The pigs' tails incident is also very common and is indeed found in another set of tales, more of the Master Thief type. Campbell's No. 45 had an entirely different set, some of them very amusing. Mac-A-Rusgaich has all three meals at once and lies down. He holds the plough and does nothing else; he sees after the mountain; literally casts ox-eyes at the master, and makes a sheep foot-path out of sheep's feet. I have taken from Campbell the direction to wash horses and stable within and without, though it does not occur elsewhere. Yet Mac-A-Rusgaich has a bout with a giant, in which he slits an artificial stomach, like Jack the Giant Killer; and this incident occurs in four other of the European tales, again showing identity. "Keep cool" is thus an interesting example of identity of framework, with variation of incident.
