Never-Reprinted Classic from Astounding SF!
Kleon of ancient Greece, who slept through the ages in a remote cavern, and Sam Ward, a contemporary American who unintentionally joined him in that sleep, wake in the future to meet Beltan, Oglarch of Hispan.
Escaping Beltan's nightmarish dystopia, the three determine to seek a culture of freedom and peace, only to fall into the hands of a regimented future state—the City of the Rocket Horde. Sentenced to die before their quest is begun, the trio must pool their knowledge if they are to survive to continue their quest.
First time in book form for the first two stories in the immortal "Past," "Present" and "Future" saga from the pages of the legendary 1930s Astounding Science Fiction.
