will have to check the authors name when i get home , it does refer to some events that are in the Emperor books i.e when he demands the pirates increase the bounty on his head appears to be true , but doesn't the Emperor books have Marius being killed in Rome by Sulla when he actually died of old age ? (been a few years since i read the Emperor series)
as Mike says a lot of the "history" of that day was propaganda , Ramesses II being a prime example , he almost makes Caesar look modest :-)
