How does “you must first enable the government to control the governed; and in the next place oblige it to control itself” reflect the principle of checks and balances?

What was the biggest difference between government in ancient athens and in ancient rome? rome was a direct democracy, and athens was not. athens allowed all citizens to vote, while rome was a republic. athens allowed women and slaves to vote, but rome did not. rome had a bicameral assembly, and athens did not.
