(country, city, house and so on) has its own special center, for each specific ritual the only one, and at the same time acting as a hypostasis of the cosmic middle, the world axis. The center of the isomorphic cosmos is the house, the hearth, sometimes a pillar supporting the roof, around which domestic rites are performed. Thus also among the Romans and the Indians the circling of the bride and groom around the hearth is the central element of the wedding ritual.”
Well, and I hope you also understand that this explanation all the more shows what this caduceus is. It turns out that there is the serpent — this is like the entire universe “Mother,” the other serpent — this is the entire universe “Father,” and they entwine this center, this pillar, this staff. It is also written in Wikipedia that “about the middle of the world it is spoken in many philosophical texts, in Greek cosmology with its distinctly expressed geocentrism. The absolute center of the world was the Earth. The conceptions of a cosmic pillar, a world tree, around which the planetary spheres revolve, were quite widespread.”
In Wikipedia also separately ‘world tree,’ more precisely, ‘world tree.’
“A mythological archetype — the universal tree, uniting all spheres of the cosmos. As a rule, its branches are correlated with the heavens, the trunk — with the earthly world, and the roots — with the underworld. The most widespread representation is the image of the mythological middle of the world, the sacred center of the Universe, performing the harmonizing role.
In the Kalevala, the Karelian-Finnish poetic epic, in the subtitle it was noted “Finnish folk songs.” The image of the great spirit signifies the world tree, which sinks its roots into the depths of the earth and with its crown reaches the heavens. In the Korsian tradition of religion upon the world tree Echki Tuma there is the nest of the sacred bird Utte Ine Normun, from which falls the egg Ine Al, from which subsequently our world arises. The shell — this is the firmament Men-El-Ya with the stars. The yolk — this is the earth with land. The white — this is the boundless ocean. In the Latvian tradition the world tree bears the name Austraskoks. The corresponding Latvian national pattern is also so named. In ancient Iran they believed that the sacred tree grows near the springs of Ardvisura. Upon it supposedly lived the king-bird Senmurv, who scattered seeds over the earth.
