The Capitol Cornerstone

Found it!  The cornerstone laid by George Washington for the Capitol building.  Washington refused to allow the new government to become a monarchy and went to great lengths to make sure he was true to the vision set forth by the framers of the Constitution.  The Presidency would wield the power of the government with the legislative and judiciary branches, through a system of checks and balances, so that tyranny would not hold sway.  Of the people, by the people, for the people.  Freedom reigns!

It speaks to the character of Washington that he demurred to service to the Constitution of the fledgling republic rather than assert his military success and accede to a throne of his creation.
