The American Progress was painted in 1872 by John Gast and it provides an image of the Westward Expansion. It shows how progress was brought progressively to the savage and unknown Western lands. Actually the East is represented on the right side of the image as the area with bright blues skies, as a contraposition to the dark West. The woman in the middle is called 'Progress', and she carries a book which represents the intellectual developments.
