De Jean de l’Ours à Persée ou de quelques modalités de la disjonction

The tale of Jean de l'ours (Jean of the Bear) is like the Bird Nester myth , but in a reversed position. Both heroes experience a vertical disjunction, the first one downwards, the second one upwards. Now, some north Amerindian versions of the Bird Nester have exactly the same structure as the Perseus myth. But in this case the story develops horizontally. The disjunction, which disappeared with verticality, is reached in a different way : by crossing the ocean.
