The text is split into two halves, headed First Act and Second Act, and describes the dreams of a man. It is written in the form of a case history, but probably can be read as autobiographical despite the absence of personal pronouns. There is no mention of studying a subject or of interviews with him. The text does not seem to be organized for dramatic effect or to be a resource, nor is it fiction, poetry, or science. T
The dreams, which are recounted in German (the rest of the text is in English) focus on a power that the man explores and slowly comes to know. The power was once on Earth and is essentially unknowable: it would view man and his accomplishments as we would view ants and an anthill. The dreamer usually refers to the power as “The King”, but twice early on uses the synonym “Kaiwan” and one other time “The Unspeakable One”. The writer absorbs pieces of knowledge through periods of intense dreaming, but interspersed are periods when he is denied dreams. Eventually he visits a city, Carcosa, which opens up his senses even more: it is a place of beauty and contentment, although challenging to his perceptions.
excerpts:
But where, who, or what is Hali? In his reading the texts, either by design or uncertainty, are obscure and even contradictory. In his dreams contradictions were also rife but he felt that Hali was the Lake itself, and the shepherds who tended sheep on it, and the twin suns that sank beneath, and the God that all venerated." "The reader imagines that this is the first race to own dominion over this planet and that it will be the last. That is wrong thinking but each must come to this conclusion on his own account — it is something one has to see for oneself, not be told. He knows his opinion would be derided or else provoke anger so he does not try to persuade.
This is the litany of the peoples of Earth. Before the first, there was blackness, and there was fire. The Earth cooled and life arose, struggling against the unremembering emptiness.
First were the five-winged eldermost of Earth, faces of the Yith. In the time of the elders, the archives came from the stars. The Yith raised up the Shoggoth to serve them in the archives, and the work of that aeon was to restore and order the archives on Earth.
Second were the Shoggoth, who rebelled against their makers. The Yith fled forward, and the Earth belonged to the Shoggoth for an aeon…
Sixth are humans, the wildest of races, who share the world in three parts. The people of the rock, the K’n-yan, build first and most beautifully, but grow cruel and frightened and become the Mad Ones Under the Earth. The people of the air spread far and breed freely, and build the foundation for those who will supplant them. The people of the water are born in shadow on the land, but what they make beneath the waves will live in glory till the dying sun burns away their last shelter.
Seventh will be the Ck’chk’ck, born from the least infestation of the houses of man, faces of the Yith. The work of that aeon will be to read the Earth’s memories, to analyze and annotate, and to make poetry of the Yith’s own understanding…
Thirteenth will be the Evening People. The Yith will walk openly among them, raising them from their race’s infancy with the best knowledge of all peoples. The work of that aeon will be copying the archives, stone to stone, and building the ships that will carry the archives, and the Evening, to distant stars. After they leave, the Earth will burn and the sun fade to ashes.
After the last race leaves, there will be fire and unremembering emptiness. Where the stories of Earth will survive, none have told us.
The last line of the book:
Some would be disconcerted by the structure of this treatise, but it is for us to walk on the Earth in Carcosa: that is the Third Act. That passage may or may not be written.
