The first earthly epoch in Steiner's cosmology, when humanity existed as warmth bodies in a recapitulation of Old Saturn, before Hyperborean, Lemurian, and Atlantean.
Polarian Epoch in Anthroposophy is the first of seven earthly epochs in Rudolf Steiner's evolutionary cosmology, recorded from the Akashic Record in Cosmic Memory (From the Akashic Record), GA 11, lectures and essays composed between 1904 and 1908. In Steiner's account the new Earth condition does not begin with mineral solidity. It begins as an astral germ holding the embryonic human being, surrounded by an envelope of the finest etheric matter. The Polarian humans exist as warmth bodies and etheric forms, not yet physically densified, with the soul still organising its etheric image from outside. The epoch recapitulates Old Saturn within Earth, lays down the seed of the physical body, and precedes the Hyperborean, Lemurian, and Atlantean epochs in the sevenfold series.
The Polarian Epoch is the opening chapter of earthly time in Anthroposophy. Steiner describes it as the moment when an astral germ, carrying everything the previous planetary stages had achieved, finds itself on a physical earth made only of finest etheric matter. Sun, earth, and moon are still one body. Humanity is a sphere of countless tiny etheric spheres, organised from the astral envelope around it.
In Steiner's Own Words
This astral germ of the earth at first contained the embryonic human being, the beginnings of the future human souls. Everything which existed in previous states as minerals, plants, and animals, had been absorbed by these human germs, merged in them. So, before man trod the physical earth, he was a soul, an astral being, and as such he finds himself on the physical earth, which then consisted of the finest matter, called in Theosophical literature the finest etheric matter. The astral human beings drew this ether round them, imprinting on it their own nature. This primeval humanity is called in Theosophical books the Polar, or First, Root-Race.
What it Means Today
The Polarian epoch sounds remote until you take it as a description of how anything new actually begins. Steiner's claim is concrete: a new condition of existence does not start with finished form. It starts with warmth, with an undifferentiated etheric matrix, with soul forces still working from outside. The dense body comes much later, after a long sequence of separations. This is the same gesture Goethe traced in living plants, the gesture the Goetheanum's Natural Science Section in Dornach has been working with for a century. The contemporary reading, advanced in particular by Jochen Bockemühl and the phenomenologists trained at the Goetheanum, is that the Polarian condition is not behind us in a fossil sense. It is the warmth pole that every living process still passes through at its earliest moment, before chemical, fluid, and solid stages crystallise out of it.
This is why Steiner placed the Polarian first and not, say, in the middle. It is the pure-warmth recapitulation of Old Saturn at the start of Earth, the same stage Bockemühl's Goethean phenomenology of warmth identifies in a sprouting seed or a forming embryo. To read the epoch this way is to take Steiner at his word that the Akashic Record is not a mythology of long ago. It is the structural law of how form arises. The Polarian first, the Hyperborean second, then Lemurian and Atlantean. Same sequence, every time something begins.
