Which ancient principles can be found in American government today

From Greece--the principles of democracy have been brought into the US government from Greece. Greek democracy was limited as it was in the founding of the US. Only elite, men were allowed the rights of citizens in both governments.  

From the Byzantine Empire--the principles of law and order came from Justinian's Code. The law code set high level law principles with each law corresponding to a punishment. The codes also set judicial principles used by the US when setting up their judicial branch of government.  

From Rome--representative government was used where members of the empire were elected or chosen to represent larger populations. In Rome, this ensured the reaches of the empire were heard and in the US representation has been used to ensure the voices of states and the people are heard in at the federal level.
