In the Norse tale of the giant who had no heart in his body, the giant tells the captive princess, Far, far away in a lake lies an island, on that island stands a church, in that church is a well, in that well swims a duck, in that duck there is an egg, and in that egg there lies my heart. The hero of the tale, with the help of some animals to whom he had been kind, obtains the egg and squeezes it, at which the giant screams piteously and begs for his life. But the hero breaks the egg in pieces and the giant at once bursts. In another Norse story a hill-ogre tells the captive princess that she will never be able to return home unless she finds the grain of sand which lies under the ninth tongue of the ninth head of a certain dragon; but if that grain of sand were to come over the rock in which the ogres live, they would all burst and the rock itself would become a gilded palace, and the lake green meadows. The hero finds the grain of sand and takes it to the top of the high rock in which the ogres live. So all the ogres burst and the rest falls out as one of the ogres had foretold.
In a Celtic tale, recorded in the West Highlands of Scotland, a giant is questioned by a captive queen as to where he keeps his soul. At last, after deceiving her several times, he confides to her the fatal secret: There is a great flagstone under the threshold. There is a wether under the flag. There is a duck in the wether's belly, and an egg in the belly of the duck, and it is in the egg that my soul is. On the morrow when the giant was gone, the queen contrived to get possession of the egg and crushed it in her hands, and at that very moment the giant, who was coming home in the dusk, fell down dead. In another Celtic tale, a sea beast has carried off a king's daughter, and an old smith declares that there is no way of killing the beast but one.
In the island that is in the midst of the loch is Eillid Chaisfhionthe white-footed hind, of the slenderest legs, and the swiftest step, and though she should be caught, there would spring a hoodie out of her, and though the hoodie should be caught, there would spring a trout out of her, but there is an egg in the mouth of the trout, and the soul of the beast is in the egg, and if the egg breaks, the beast is dead. As usual the egg is broken and the beast dies.
In an Irish story we read how a giant kept a beautiful damsel a prisoner in his castle on the top of a hill, which was white with the bones of the champions who had tried in vain to rescue the fair captive. At last the hero, after hewing and slashing at the giant all to no purpose, discovered that the only way to kill him was to rub a mole on the giant's right breast with a certain egg, which was in a duck, which was in a chest, which lay locked and bound at the bottom of the sea. With the help of some obliging animals, the hero made himself master of the precious egg and slew the giant by merely striking it against the mole on his right breast. Similarly in a Breton story there figures a giant whom neither fire nor water nor steel can harm. He tells his seventh wife, whom he has just married after murdering all her predecessors, I am immortal, and no one can hurt me unless he crushes on my breast an egg, which is in a pigeon, which is in the belly of a hare; this hare is in the belly of a wolf, and this wolf is in the belly of my brother, who dwells a thousand leagues from here. So I am quite easy on that score. A soldier contrived to obtain the egg and crush it on the breast of the giant, who immediately expired. In another Breton tale the life of a giant resides in an old box-tree which grows in his castle garden; and to kill him it is necessary to sever the tap-root of the tree at a single blow of an axe without injuring any of the lesser roots. This task the hero, as usual, successfully accomplishes, and at the same moment the giant drops dead.
The notion of an external soul has now been traced in folk-tales told by Aryan peoples from India to Ireland. We have still to show that the same idea occurs commonly in the popular stories of peoples who do not belong to the Aryan stock. In the ancient Egyptian tale of The Two Brothers, which was written down in the reign of Rameses II., about 1300 B.C., we read how one of the brothers enchanted his heart and placed it in the flower of an acacia tree, and how, when the flower was cut at the instigation of his wife, he immediately fell down dead, but revived when his brother found the lost heart in the berry of the acacia and threw it into a cup of fresh water.
