Fifty Thousand Years

According to the Chronology of the Psychotechnic Series prepared by Sandra Miesel, the Third Dark Ages begin in 3200 and "The Chapter Ends" is set post-4000. Miesel's interstitial note introducing "The Chapter Ends" reads:

"By the uncertain dawn of the fifth millennium, Earth's farflung children had all but forgotten her." (Starship, p. 252)

However, "The Chapter Ends" itself says:

"'The Sirius Sector has been an isolated, primi - ah - quiet region since the First Empire fell, fifty thousand years ago.'" (p. 263)

The time scale and also the references both to a fallen First Empire and to Sirian Sector planets inhabited by peasants place this work more in the milieu of Anderson's "Flight to Forever." Again, the reference to Sol City as the capital of the First Empire (p. 272) prima facie links this work to Anderson's "The Star Plunderer," although that pulp short story was instead shoehorned into the author's later Technic History.

The political units in the Psychotechnic History are Unions (Solar and Stellar), not Empires. We are told enough about the First Empire to know that it is not the Stellar Union remembered under a different name.

What links "The Chapter Ends" to the Psychotechnic History? References to psychotechnicians, an Integrator and a trained nervous system. Also, in The Peregrine, humanity is expanding towards the Sagittarii. In "The Chapter Ends," the bulk of humanity has migrated to the Galactic Center and one, visiting Earth, says:

"'This part of space means nothing to us any more; it's almost a desert. You haven't seen starlight till you've been by Sagittarius.'" (p. 262)

A concluding note on an unfamiliar word:

"...he went with the Nomads through that abatis of woods." (The Peregrine, Chapter XX, p. 178)

Near The End Of The Rebel Worlds: The Milky Way And A Buckethead

The Rebel Worlds.

Dominic Flandry looks out from a spaceship:

"Twice he identified slivers of blackness crossing the constellations and the Milky Way; nearby warcraft."
-CHAPTER FIFTEEN, p. 504.

The captured ruka links with Cave Discoverer's noga and krippo to form the miserable entity who self-designates "Woe." Heesh was first mentioned in the opening paragraphs of the novel. See here. This noga and krippo were already accustomed to linking with another foreign ruka to form Raft Farer who was also mentioned at the beginning.

Before leaving Dido, Flandry and Kathryn were enclosed by:

"Steamy heat and jungle abatis..."
-CHAPTER THIRTEEN, p. 488. (Scroll down.)

Flandry thinks of Hugh McCormac as a "...bucketheaded mass murderer..." (CHAPTER TWELVE, p. 485) and Manse Everard uses the phrase, "...a blind buckethead..." in Time Patrol, p. 61. Technic History-Time Patrol parallels are always pleasing and have been noted before.  

Pterosaurs

SM Stirling, The Sky People (New York, 2006).

On Venus, pterosaurs (see image) - not pterodactyls - attack the Vepaja. How many sf writers present dinosaurs surviving into the present? For example, James Blish wrote The Night Shapes. Poul Anderson has characters encountering dinosaurs but that is because they have time traveled, in "Wildcat" and "The Nest."

Marc keeps noticing oddities about the Englishman but does not draw conclusions from them. The reader has been informed that the supposed Englishman is in fact a French spy. Was the author right to inform us of this or should he instead have left us to draw conclusions from the oddities? Or is he preparing us for some other surprise? I am unwise to speculate while still reading.

Words That I Either Have Not Encountered Before Or At Least Was Unsure Of Their Meanings
tumpline (p. 138)
abatis (p. 180)
Ainu (p. 185)

A Clever Invented Word
Venus grows sham bamboo, thus shamboo.

Literature In Alternative History
Marc has often reread At The Earth's Core and A Princess Of Mars (p. 180). So have some of us but the point here is that many more people would do so if it turned out that ERB's fictional Solar System was closer to the truth.

I noticed some perhaps unintended parallels between Anderson's Aeneas and ERB's Barsoom. See here.
