Im not making the connections the top comment is. Her SPQR books are nice alternative history from a real historian. At a guess the parent comment is referring to some cultural aspects based on earlier roman and not our current judeo-christian values in the west. An emphasis on biological advancements, moralality that serves status hierarchy and empire, “polycule” style relationships in military and socioeconomic units, a different view on “sanctity of life.” Off the top of my head.
