The Lost Planet

A Circus Of Hells.

Rax asks Djana:

"'Where is the lost planet? What is its nature?'"

-CHAPTER THREE, p. 216.

An evocative phrase like "the lost planet" might have different connotations for different readers. In fact, googling brings up multiple references. In the 1950s, I saw some episodes of a TV series and read perhaps the first two juvenile novels connected with this series. See here. I am finding the Wikipedia accounts slightly inconsistent. I like the idea of Space Agent From The Lost Planet as the last of six Lost Planet books and the first of three Space Agent books. Similar crossover titles are Tarzan At The Earth's Core and She And Allan.

This has taken us a long way from Poul Anderson's characters, Rax and Djana, but that is the nature of literary connotations. Possibly Anderson intended the phrase, "lost planet," to have just a literal meaning with no other implications but that is not necessarily how it works in the minds of his readers.

Needless to say, Anderson's "lost planet," Wayland, is entirely his own creation and in no way derivative from anyone else's ideas.
