He imagined a town called A. Around the communal fire they're shaping arrowheads and carving tributes o the god of the hunt. One day some guys with spears come over the ridge, perform all kinds of meanness, take over, and the new guys rename the town B. Whereupon they hang around the communal fire sharpening arrowheads and carving tributes to the god of the hunt. Some climatic tragedy occurs -- not carving the correct tributary figurines probably -- and the people of B move farther south, where word is there's good fishing, at least according to those who wander to B just before being cooked for dinner. Another tribe of unlucky souls stops for the night in the emptied village, looks around at the natural defenses provided by the landscape, and decides to stay awhile. It's a while lot better than their last digs -- what with the lack of roving tigers and such -- plus it comes with all the original fixtures. they call the place C, after their elder, who has learned that pretending to talk to spirits is a fun gag that gets you stuff. Time passes. More invasions, more recaptures, D, E, F, and G. H stands as it is for a while. That ridge provides some protection from the spring floods, and if you keep a sentry up there you can see the enemy coming for miles. Who wouldn't want to park themselves in that real estate? The citizens of H leave behind cool totems eventually toppled by the people of I, whose lack of aesthetic sense if made up for by military acumen. J, K, L, adventures in thatched roofing, some guys with funny religions from the eastern plains, long-haired freaks from colder climes, the town is burned to the ground and rebuilt by still more fugitives. This is the march of history. And conquest and false hope. M falls to plague, N to natural disaster -- same climatic tragedy as before, apparently it's cyclical. Mineral wealth makes it happen for the O people, and the P people are renowned for their basket weaving. No one ever -- ever -- mentions Q. The dictator names the city after himself; his name starts with the letter R. When the socialists come to power they spend a lot of time painting over his face, which is everywhere. They don't last. Nobody lasts because there's always somebody else. They all thought they owned it because they named it and that was their undoing. They should have kept the place nameless. They should have been glad for their good fortune, and left it at that. X, Y, Z.
