What a thing it must have been, during the rise of the empires of man, to not know what lay beyond the horizon. To be able to walk as far as your feet could take you and stand on a mountain ridge looking over unknown plains, knowing there was most certainly something there beyond where the land rose to meet the sky, it was just a matter of going to see it. Theories had been cast, stories may have even come back from those who had kept walking, but nothing was certain, and everything was possible. You didn’t need a rocket to explore the unknown, you just needed the desire to not turn around.
At the same time, it’s also a wonder that some wanted to possess it all when they could barely imagine the extent of it. The Mongols, Alexander the Great, the emperors of ancient Rome… Is it vision or madness to strive to find the edge of the universe simply so you could call it your own?
