I love this kind of book that chronicles the end and rebirth of a civilization and this topic has clearly well inspired this "golden sphere" in which Erle Cox built a meaningful account before René Barjavel (the latter decline Moreover in my esteem with his remake of "ancient times", yet not bad). Erle Cox assumed that a brilliant civilization existed in the past and that representatives were saved for future time in order to revive it. Yes, but this famous civilization has built its power on a eugenics excessive and suppression of the weak. We can see where the author takes us in dealing with the removal of inferior races or genetic selection. Written before the war, this theme nagging scientific circles and the author took the opportunity to plant her banderillas in the body. Under the seductive outside improving physical qualities and elimination of diseases by natural selection, and with a most charming appearance with the beautiful Hyéranie, the lost civilization between open conflict with humanistic choice of some leaders of the Earth after the First World War. The debate raised by Erle Cox are well chosen in this novel that reads in one sitting. It would be pure anticipation if there were not also a powerful love story, not only between Dundas, the main protagonist, and Hyéranie but also with a young woman who also likes Dundas. The place of history and its tragic end shows that love stories can preserve the world scientific temptations. If hell is paved with good intentions, the ideal proposed by Hyéranie civilization in its golden sphere like the worst sections of Paris-Roubaix!
A novel devouring but whose formal presentation has some flaws in this edition as spelling mistakes quite annoying towards the end of the book. The haze gain in Earth editions improvement on this point.
