Comparing Fictional Universes

See Social Developments In The Technic History and compare:

"...they lived in primitive fashion for lack of machinery; freight costs from Earth were enormous."
-Poul Anderson, The Avatar, V, p. 40.

Also, the description of the city of Eopolis on the colonized planet, Demeter, recalls cities on Hermes and Avalon in the Technic History.

In Eopolis:

the sun, Phoebus, sets behind the dome of the Capitol on Anvil Hill at the end of Pioneer Avenue;

the Europa River flows into Apollo Bay and the Hephaestian Sea;

nearby farms of Terrestrial crops are green against native blue mariflora and raincatch;

native winged species cruise in the cloudless azure sky;

cool air bears wild scents;

Hidden Mountain Road, where the Brodersens live, is gold in the evening, with gardens of mixed ecologies.
