Bartleby is a combination of post - the Liberty Pole - as body, and woman - the Liberty Lady - as soul. Google half-dimes from 1853, or better yet go to Greatseal.com and look at the versions of the Liberty Lady/Pole that competed with Eye for pride of place on the Great Seal. As a past incarnation of Liberty, the symbol comes back to haunt the current symbols of the Great Seal of the United States, engaged in imprinting themselves as copies on stationary, seals, stamps, coins and statuary. Turkey and Nippers are American Eagles, one the original, the second a newer realization in 1841. Ginger Nut is the cake of stars (cake of nuts) above the American Eagle's head. The I - the narrator - is the Eye that floats in his "snug" office above the Pyramid's - the lower office's - top. Take out a dollar bill. Match the characters, then read the story again. The story becomes even more funny, and the pathos of poor Lady Liberty and her vanishing act finally makes it touching as well.
