I got a rejection back from the The New Yorker for my little bit of wacky alternate history, "Custodes". The editor wrote me a note again, said "an interesting play of anachronisms, thanks for the original story."
The story supposes Archimedes invented the electric motor, so by the time of the Roman Empire of the first century they have subways and television. Therefore, the persecution of the Christians is televised as reality television ("Custodes" = "Cops").
I especially like the piece of business when the family gets the first color television on their block. The "Rainbow Teleceptor" is delivered by the department store that uses the logo of the Emperor and Stag, "Caesar and Roebuck".
