This novel is actually a collected series of connected stories set about 1300 years after “one person was nailed to a tree” for being nice to people. Sorry, couldn’t resist.
But this does not mean this series of stories is humour. Actually it is quite serious, but the premise is that the Byzantium Empire never fell apart. The Empire is alive and thriving and so this is an alternate history work which, I believe, Turtledove is known for.
The stories themselves were published from 1985 through 1987 in various magazines.
Now I will be the first to admit that my “knowledge” of Byzantium history is shaky at best and non-existent for the most part, but that didn’t stop me from enjoying the stories at all. But, I suppose, if you knew a great deal about Byzantium (and Turtledove has a PH.D. in Byzantium history) then you may get more out of it.
Anyhow, this series of stories centers around one man, Basil Argyros, a Roman who, as the stories progress, rises through the ranks of Byzantiums as he discovers, or rather uncovers, certain major developments in the developing fictional world.
He acts as a spy and travels to distant parts of the world to investigate strange happenings, some which appear to be magic. Discoveries touched upon are the telescope, small pox vaccine, gunpowder, the printing press and even distilled spirits. Quite a list and that is not all.
Woven into these discoveries is the story of Argyros himself, and he gets himself into and out of many scrapes. The last three stories have him up against a delightful nemesis; beautiful, crafty and deadly. Of course they have several memorable encounters, but I won’t spoil that fun for you.
Worth while read for sure, but my huge lack of historical knowledge probably left me out in the cold and I may have missed a lot of how Turtledove changed the “real” history of our world.
Collected in the “Isaac Asimov presents” hardback series, I think you can still find this one kicking around. If you do, it is worth picking up.
