In his 1907 essay on Chukchi mythology, Bogoraz describe their cosmogony as follows:
According to the cosmogonical beliefs of the Chukchee, there are several worlds situated one above another, in such a manner that the ground of one forms the sky of the one below. The number of these worlds is stated as five, seven, or nine. These worlds are arranged symmetrically above and below the earth, each of the lower worlds having a corresponding one above it. [...] All these worlds, as said before, are joined by holes situated under the Polar Star. Shamans and spirits while going from one world to another slip through these holes.
And earlier, while describing the star itself:
The most important is the Polar Star, which is called in the Chukchee language Ilu'kalin e'nier or Ilu'k-e'iner ("motionless star"), or Aglqe'p- e'ner ("nail star"), or Unp-e'nier ("the pole-stuck star"). This latter name occurs throughout Asia. It suggests the existence of a simile in which all other stars move around the Polar Star as horses or reindeer move around a pole to which they are tethered. The house of the Polar Star stands in the zenith. Directly under it is a hole through which it is possible to pass from one world to another. Through a series of these holes the Polar Star can be seen in al the lower and higher worlds, while the other constellations change with the diferent worlds. Carrying this idea further, the house of the Polar Star is supposed to be higher than that of any other star. It is made of a material similar to ice, and on the top of it is set the beacon - lamp of the star.
The Chukchi being a people living in the arctic Siberia, one would indeed expect the North Star to be central to their cosmogony. Hence my question: did the other people indigenous to the Arctic develop similar cosmogonical beliefs surrounding the North Star?
