I'm thinking this is because of the campaign of Alexander. Like Massilia has greek shrines/temples, Cyrene was part of the Macedon Empire under the rule of Alexander himself. After all this is after Alexander's death, hence Ptolemaic egypt, the Selucid Empire and the Greek Cities. My friend told me that it also transverts to Greek rule (presumably if you haven't modded the game or if you are playing as the Greeks) and it's amazing how well they stuck to the reality of it.
