SYMBOLS???

I have done much more research and I have found that there are symbols in the painting. What are they? And what do they stand for?

The painting is full of symbolism, drawn from both American and ancient Roman symbols of the Roman Republic. Stuart painted Washington from life, showing him standing up, dressed in a black velvet suit with an outstretched hand held up in an oratorical manner (which could be characterized as "commanding and stern yet open and inclusive"). In the background behind Washington is a row of two Doric columns, with another row to the left. Wrapped around and between the columns are red tasseled drapes. Washington’s suit is plain and simple, and the sword that he holds on his left side is a dress sword and not a battle sword (symbolizing a democratic form of government, rather than a monarchy or military dictatorship). In the sky, storm clouds appear on the left while a rainbow appears on the right, signifying the American Revolutionary War giving way to the peace and prosperity of the new United States after the 1783 Treaty of Paris. The medallion at the top of the chair shows the red, white, and blue colors of the flag. On and under the tablecloth-draped table to the left are two books: Federalist—probably a reference to the Federalist Papers—and Journal of Congress—the Congressional Record. Another five books are under the table: the three to the right are General Orders, American Revolution, and Constitutional Bylaws—symbolizing Washington's leadership as commander-in-chief of the Continental Army and president of the Constitutional Convention. The pen and paper on the table signify the rule of law. The leg of the table is shaped like a fasces, an ancient Roman symbol of power and authority. On the far left of the table is a silver inkwell, emblazed with George Washington's coat of arms (see Syng inkstand). A white quill rests upon silver dogs, ancient symbols of loyalty. Behind the table is a large black hat. Washington’s unusually clenched facial expression comes from his famous false teeth.
